Answer:

-8

Step-by-step explanation:

Answer:

x = -8

Step-by-step explanation:

[tex]\frac{3}{4}x+10=4[/tex]

[tex]\frac{3}{4} x-10[/tex] [tex]-10[/tex]        Subtract 10 from both sides

[tex]\frac{3}{4}x=[/tex]       [tex]-6[/tex]        

[tex]\frac{3}{4}(-8)[/tex]  [tex]=-6[/tex]        Substitute x for [tex](-8)[/tex] then Multiply [tex](-8)[/tex] by [tex]\frac{3}{4}[/tex]

[tex]-\frac{24}{4}[/tex]     [tex]=-6[/tex]        Simplify [tex]-\frac{24}{4}[/tex]

     [tex]-6=-6[/tex]      

Answer:

Step-by-step explanation:

To solve this, we first need the area of the square, then subtract from it the area of the circle. Since our instructions tell us to round to the nearest hundredth, we will use 3.1415 for pi. First the square:

A = s * s so

A = 15 * 15 and

A = 225; next the circle:

A = 3.1415 * 7.5*7.5 (the area of a circle is pi times the radius squared. The radius is half of the diameter which is 15, so r = 7.5) so

A = 176.709

Subtracting the area of the circle from the area of the square:

225 - 176.709 = 48.29 ft squared.

Answer:

The​ odds, in the most simplified​ form, are 7 to 3 against a randomly selected​ 18- to​ 34-year-old having cursed at his or her computer.

Step-by-step explanation:

Given

[tex]p = 30\%[/tex] ---- proportion that cursed their computer

Required

Odds against the selected

Using the complement formula, the proportion that the selected has not cursed at their computer is:

[tex]p' = 1 - p[/tex]

[tex]p' = 1 - 30\%[/tex]

[tex]p' = 70\%[/tex]

So, the odds against the selected is:

[tex]Odds = p' : p[/tex]

[tex]Odds = 70\% : 30\%[/tex]

Divide by 10%

[tex]Odds = 7: 3[/tex]

Answer:

810 AUD

Step-by-step explanation:

t is time in months: you have to substitute with the number of months given from the question.

C=65t + 30 ==> substitute t with 12 since the question provided you the number of months.

--> C = 65(12) + 30 = 780 + 30 = 810

Answer:

53 gallons of fuel

Step-by-step explanation:

Step 1: Set up a fraction given the data (Let "x" represent the distance in miles.)

[tex]\frac{10}{250} = \frac{x}{1325}[/tex]

Step 2: Divide the given values (The given values are 10 over 250. We are doing this because we need to know the difference between those two figures.) (Trick: For this case, all you need to do is cancel both zeros and the answer is 0.04 once divided)

[tex]\frac{10}{250}\\\\10 \div 250\\\\= 0.04[/tex]

Step 3: Multiply the result to the last value (Since we've found the difference between them by division, we will have to do the opposite operation in order to find the answer.)

[tex]1325 \times 0.04\\\\= 53[/tex]

Therefore, 53 is the amount of gallons of fuel needed.

Step-by-step explanation:

OCB=CBO(base angle of isosceles triangle are equal)

now,

OCB+CBO+BOC=180°(sum of angles of triangles)

BOC=180-62

BOC=118°

again,

x=BOC/2{inscribed angle is half of central angle standing on Same base}

x=118/2

x=59°

Answer:

B

-15 < 99 and | -9 | < | 15 |

Step-by-step explanation:

Those lines " | " refer to absolute value, meaning it is the distance from 0. You can easily get this just by cutting off a negative sign.

So we do know -9 is greater than -15 obviously, and the absolute value of -9 is 9, because -9 is 9 units from 0.

-15 is 15 units away, so when using absolute value, -15 is greater than -9.

Btw, you can only give one brainliest, you don't get the option to give two on brainly.

Just saying.

Idc if I get it honestly.

Answer:

4x(3x^2 + 1)(x – 5) glad to help!!!!

Answer:

Step-by-step explanation:

The length of the ladder is the length of the hypotenuse of the right triangle formed. Since the height up the building is based on the distance the ladder is from the base of the building, and that distance is x, then the height up the building is x + 7. So what we have is a right triangle with one leg measuring x, the other leg measuring x + 7, and the hypotenuse measuring 13. Set up using Pythagorean's Theorem:

[tex]13^2=(x+7)^2+x^2[/tex] and do some simplifying. The left side is easy since 13-squared is 169; the right side not so much. We first have to expand that set of parenthesis by multiplying x + 7 by itself twice to get a second degree polynomial:

[tex](x+7)(x+7)=x^2+14x+49[/tex] and now we have:

[tex]169=x^2+14x+49+x^2[/tex] which simplifies down a bit to

[tex]169=2x^2+14x+49[/tex]

The only way to solve this for x, the height up the side of the building, is to factor. In order to do that, everything has to be on one side of the equals sign, setting the whole messy thing equal to 0:

[tex]2x^2+14x+49-169=0[/tex] and

[tex]2x^2+14x-120=0[/tex]. Begin by factoring out a 2:

[tex]2(x^2+7x-60)=0[/tex] and then factor the remaining quadratic using whatever method you are currently using in class to solve for x. Doing this will give that

x = -12 and 5. Since a side length will never be negative, we determine that x = 5 which is the distance between the bases of the buildings, and the height up the building where the ladder hits it is 12.

Answer:

x= 0

Step-by-step explanation:

6x-4=2(3x-2)

or,6x-4=6x-4

or,x=o

There are infinite solution of the expression.

We have to given that,

An expression to solve,

6x - 4 = 2 (3x - 2)

Now, We can simplify as,

6x - 4 = 2 (3x - 2)

Apply distributive property,

6x - 4 = 6x - 4

Combine like terms,

6x - 6x = 4 - 4

0 = 0

Hence, There are infinite solution of the expression.

I took the MAP Test.

Answer:

The value for x is -2 and the value for y is -10 .

Step-by-step explanation:

Firstly , let's write the equations

solving equation 1 to get the values of x

          or ,    -2x+3=7          

      or,  -2x+3-3 =7-3 (subtracting -3 on both sides )

       or ,  -2x=4

        or,  -2x/2  =   4/2  (dividing  by two on both sides )

         or ,  -x =2

           or  x = -2

now let's substitute the values of x  in the equation 2

           3x+1 =5+y (writing second equation as it is )

           or, 3x+1-1=5+y-1 (subtracting  -1 on both sides )

            or , 3x = 4+y  

              or , 3 × -2 = 4+y  (substituting the values of x from equation 1 )

                or ,  -6  =  4 +y

                   or ,  -6-4 = 4+y-4 ( subtracting -4 on both sides  )

                     or ,    -10 = y

      Therefore the values of x and y is -2 and  -10 respectively .

                Hope it helped you .  If you find the answer useful  please rate brainliest , If not Thanks anyway .

hi hlo wat is ur help tell me quick

Answer:

Step-by-step explanation:

log 3y = log(y)^3 (exponent)

or

= log(y)*log(y)*log(y)  (multiples)

The logarithmic expression y = log(3y) can be written as sum or difference of common logarithms as log(3y) = log(3) + log(y).

        [tex]$\log_{b}({b^x})=x[/tex]           {where [b] is logarithmic base}

Given is the following logarithmic expression as -

y = log(3y)

We have the following logarithmic expression -

y = log(3y)

Using the identity of logarithm -

log(AB) = log(A) + log(B)

log(3y) = log(3) + log(y)

Therefore, the logarithmic expression y = log(3y) can be written as sum or difference of common logarithms as log(3y) = log(3) + log(y).

Answer:

x=6

Step-by-step explanation:

Hi there!

1) Determine the perimeter of the square

We're given that the perimeters of the square and the rectangle are equal. Therefore, after finding the perimeter of the square, we will also know the perimeter of the rectangle.

Find the side length of the square using the area formula:

[tex]A=l^2[/tex] where l is the side length

Plug in the given area 121 in.²

[tex]121=l^2[/tex]

Take the square root of both sides

[tex]\sqrt{121} = \sqrt{l^2} \\11=l[/tex]

Therefore, the side length of the square is 11 inches. Plug this into the perimeter formula:

[tex]P=4l[/tex] where l is the side length

[tex]P=4(11)\\P=44[/tex]

Therefore, the perimeter of the square is 44 inches. The perimeter of the rectangle is also 44 inches.

2) Determine the value of x

Use the formula for the perimeter of a rectangle:

[tex]P=2(l+w)[/tex] where l is the length and w is the width

Plug in 3x and x-2 as the length and width

[tex]P=2(3x+(x-2))\\P=2(3x+x-2)\\P=2(4x-2)[/tex]

Plug in the perimeter 44 in.

[tex]44=2(4x-2)[/tex]

Expand the parentheses

[tex]44=8x-4[/tex]

Add 4 to both sides to isolate 8x

[tex]44+4=8x-4+4\\48=8x[/tex]

Divide both sides by 8 to isolate x

[tex]\frac{48}{8}=\frac{8x}{8} \\6=x[/tex]

Therefore, the value of x is 6.

Answer:

16 cans per minute

Step-by-step explanation:

Its simple 80 divided by 5 is 16 so ever minute 16 cans are packed.

The ratio of the cans to minutes is 80 : 5 or 16 : 1, and the machine can pack 16 cans per minute if a machine can pack 80 cans in 5 minutes.

It is defined as the comparison between two quantities that how many times the one number acquires the other number. The ratio can be presented in the fraction form or the sign: between the numbers.

A machine can pack 80 cans in 5 minutes.

let's denote the number of cans with X and

Time with T

So we have to find the value of X : T

X = 80 and

T = 5 minutes

X : T = 80 : 5  or

X : T = 16 : 1   (divide by 5 on both sides)

It means the machine can pack 16 cans per minute.

Thus, the ratio of the cans to minutes is 16 : 1, and the machine can pack 16 cans per minute if a machine can pack 80 cans in 5 minutes.
