Answer: Associative Property

Step-by-step explanation:

This is a binary operation in which rearranging the parenthesis in an expression has no effect on the answer.

Answer:

Associative Property

Step-by-step explanation:

The associative property is a property of some binary operations, which means that rearranging the parentheses in an expression will not change the result.

Answer:

The hypotenuse is 15. Please give Brainilest

Step-by-step explanation:

Since it is a right triangle, it probably follows the Pythagorean theorem

basically saying two legs squared equal hypotenuse squared

[tex]a^2+b^2=c^2[/tex]

In this case, if you know your Pythagorean theorem triples, then the

answer will be 9,12,15

If you don't let me explain

[tex]9^2 = 81\\12^2 = 144\\15^2=225\\\\a^2+b^2=c^2\\9^2+12^2=15^2\\81+144=225\\[/tex]

This is correct

If you don't know how I got this, learn the first five or six Pythagorean theorem triples, and these will be a piece of cake for you. Remember this only works for right triangle though.

Answer:

[tex]y=-2x+2[/tex]

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when x=0).

1) Determine the slope (m)

[tex]m=\displaystyle\frac{y_2-y_1}{x_2-x_1}[/tex] where two points that fall on the line are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the given points (4, -6) and (0, 2):

[tex]m=\displaystyle\frac{-6-2}{4-0}\\\\m=\displaystyle\frac{-8}{4}\\\\m=-2[/tex]

Therefore, the slope of the line is -2. Plug this into [tex]y=mx+b[/tex]:

[tex]y=-2x+b[/tex]

2) Determine the y-intercept (b)

The y-intercept occurs when x=0. We are given that (0,2) falls on the line, so therefore, 2 is the y-intercept. Plug this into [tex]y=-2x+b[/tex]:

[tex]y=-2x+2[/tex]

I hope this helps!

Answer:

y = - 2x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m =

with (x₁, y₁ ) = (4, - 6) and (x₂, y₂ ) = (0, 2 )

m =  =  =  = - 2

The line crosses the x- axis at (0, 2 ) ⇒ c = 2

y = - 2x + 2 ← equation of line

Answer:

Step-by-step explanation:

4 3/5 + 5 1/2= (10 1/10)

Step 1: Find the common multiple between the numbers, and simplify-

4 3/5=4 6/10 5 1/2= 5 5/10

Step 2: Convert to improper fractions-

4 6/10 as an improper fraction is 46/10 and 5 5/10 as an improper fraction is 55/10 (Formula for mixed numbers to improper fractions is denominator multiplied by whole number plus numerator)

Step 3: Add numerator of improper fractions, then add back denominator-

46+55=10 1 numerator:101 denominator:10 101/10

Step 4: Convert into mixed number-

101/10= 10 1/10

ANSWER: 10 1/10

Answer:

10.1

Step-by-step explanation:

Conversion a mixed number 4 3/

5

to a improper fraction: 4 3/5 = 4 3/

5

= 4 · 5 + 3/

5

= 20 + 3/

5

= 23/

5

To find a new numerator:

a) Multiply the whole number 4 by the denominator 5. Whole number 4 equally 4 * 5/

5

= 20/

5

b) Add the answer from previous step 20 to the numerator 3. New numerator is 20 + 3 = 23

c) Write a previous answer (new numerator 23) over the denominator 5.

Four and three fifths is twenty-three fifths

Conversion a mixed number 5 1/

2

to a improper fraction: 5 1/2 = 5 1/

2

= 5 · 2 + 1/

2

= 10 + 1/

2

= 11/

2

To find a new numerator:

a) Multiply the whole number 5 by the denominator 2. Whole number 5 equally 5 * 2/

2

= 10/

2

b) Add the answer from previous step 10 to the numerator 1. New numerator is 10 + 1 = 11

c) Write a previous answer (new numerator 11) over the denominator 2.

Five and one half is eleven halfs

Add: 23/

5

+ 11/

2

= 23 · 2/

5 · 2

+ 11 · 5/

2 · 5

= 46/

10

+ 55/

10

= 46 + 55/

10

= 10.1

Answer:

y = 5

Step-by-step explanation:

Ok so you need to move y to its own spot so either on the right or left of the equation. BUT i recommend leaving it and instead moving -10 to the other side. REMEMBER when you move a number to the other side of the equation you change its value so instead of -10 it will become +10. so you will get 10-5=y so 5=y, if you want the y to be on the other side flip them around -y=-5(since you switched them you need to make them minus, or plus if the number was originally negative) SINCE you have minuses on both sides you can cancel them out and you will be left with y=5.

Why you need to reorder:

you need to reorder to find Y there is no way you can find Y without reordering. When you are reordering remember that Y has to be by itself in one side of the equation.

Answer: 64 friends were called on Sunday, 4^3

Step-by-step explanation:

The number of friends that were called on Sunday are; 64 friends.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

On Friday, the number of friends Sharon called 4 friends

On Saturday, the number of each of those 4 friends called 4 different friends.

Therefore, the number of friends on Saturday = 4 × 4

= 16

The number of friends called on, Sunday = 16 × 4

= 64

Hence, the number of friends called on Sunday is; 64.

Answer:

for plan B if he rides for 100 miles he will pay 60$

for plan A if he rides for 100 miles he will pay 60$

Step-by-step explanation:

the reason is that B. 100x0.60=60

and A (100x0.10)+50=60

Answer:

100 miles

Step-by-step explanation:

If Alonzo drives 0 miles, then the first plan would cost him 50 dollars and the second plan would cost him nothing.

If Alonzo drives 10 miles, then the first plan would cost him 51 dollars and the second plan would cost him 6 dollars.

From these statements, we can observe that the second plan is increasing at a rate 6 times the first one and will overtake it at one point.

Our solution is the point of intersection between these two functions - where they cost the same.

To find this, equate

0.1x + 50 = 0.6x

where x is the number of miles Alonzo drives,

multiply the equation with 10 to get,

x + 500 = 6x

subtract x,

5x = 500

and divide 5,

x = 100.

So at 100 miles, both plan 1 and 2 will cost 60$. This is our answer. Good Luck!

Answer:

The initial value is 4

Step-by-step explanation:

the linear equation is 2/1 or 2. the equation is y = 2x + 4. In other words every time it rise 2 the line move the right 1. We just have to retrace our steps and since 3 - 3 = 0 we have to retrace it 3 times and 6 times on the y axis which gets us 4.

Answer:

There are 20,000 Beatles in the total population

Step-by-step explanation:

59 Beatles out of the 2,000 are marked (2.95% or 59/2000)

-----------------------------------------

1 / 0.0295 = 33.8983051

That means that the total population is 33.89 times larger than the 590 marked beatles.

33.8983051 x 590 = 20,0000 Beatles total

Answer:

Approximately 20,000 beetles

Step-by-step explanation:

The answer is approximately 20,000 beetles because Joe found 590 beetles and marked them. When he found the other 2,000 beetles, 59 of them were marked. 59 is 10% of 590. Since Joe found 2,000 beetles that must be 10% of some number. To find that number, you must multiply 2,000 by 10. So 2,000 x 10 is 20,000, so there is approximately 20,000 beetles
