Answer:

5

Step-by-step explanation:

2x + 3y = 12

2x - 2y = 2 // subtract second equation from first

5y = 10

y = 2

x = (2 + 2y) / 2 = y + 1 = 3

x + y = 5

Answer:

B

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

let h be the hypotenuse, then

h² = 6² + 18² = 36 + 324 = 360 ( take the square root of both sides )

h = [tex]\sqrt{360}[/tex]

   = [tex]\sqrt{36(10)}[/tex]

   = [tex]\sqrt{36}[/tex] × [tex]\sqrt{10}[/tex]

   = 6[tex]\sqrt{10}[/tex] → B

Answer:

3 hours

Step-by-step explanation:

Max cleans the house in 12 hours

Max in 1 hour cleans: 1/12 part of the house

Maggie cleans the house in 4 hours

Maggie in 1 hour cleans: 1/4 part of the house

In 1 hour they together do: 1/12 + 1/4 = 1+3/12 = 4/12 = 1/3 work

1 hour===1/3 work

X hours== 1 work

X/3 = 1

X = 3 hours.

Hence, they together complete the work in 3 hours.

And so, the sister is correct.

Hope it helps.

Answer:

Graph E

You're welcome.

As a little tip that's helped me personally when I was taking algebra, making equations for word problems feels a lot easier when you "translate" equations you make into words to make sure that you're using the right equation.

Let's boil down what the question tells us. 5/6 of the price tag of a bike from Store B is the price of a bike from Store A, which is $150.60. Let's use the variable 'b' to represent the price of Store B's bike.

[tex]\frac{5}{6}[/tex] * b = 150.60

Try "translating" the equation above. "5/6 of the price of a Store B bike is equal to 150.60." That seems about right, doesn't it? Let's isolate 'b' so we can get an official answer.

Multiply both sides by 6 to get rid of the denominator:

[tex]\frac{5b}{6}[/tex] * 6 = 150.60 * 6

5b = 903.6

Divide both sides by 5 to get rid of b's coefficient:

[tex]\frac{5b}{5}[/tex] = [tex]\frac{903.6}{5}[/tex]

b = 180.72

The price of a bike from Store B is $180.72

Answer:

≈119.3

Step-by-step explanation:

The area for circumference is as follows:

[tex]C = 2\pi r\\or\\C = d\pi[/tex]

The above equations mean the same thing, because the diameter is just 2 times the radius.

Anyhow, we insert this value into the equation...

[tex]C = 2\pi(19)\\C = 38(3.14)\\C = 119.32\\[/tex]

Answer:

2926 cm²

Step-by-step explanation:

The area of a rectangle is 325 cm^2. What is the area of a rectangle in cm^2 with sides 3 times as large?

Step 1

A rectangle has both Length and Width

Let us assume the Length = Width

The area of a rectangle is 325 cm²

Area = Length × Width

325 cm² = L²

L = √325 cm²

L = 18.027756377 cm

Approximately = 18.03 cm = Widtdh

Step 2

What is the area of a rectangle in cm² with sides 3 times as large?

From Step 1

L = 18.03cm

3 times as large = 18.03 cm × 3

= 54.09 cm

The Area for this rectangle

= A = L²

A =( 54.09 cm)²

A= 2925.7281 cm²

Approximately = 2926 cm²

[tex]\frac{x+xy}{y}[/tex]

Step-by-step explanation:

Given

[tex]\frac{x}{y}[/tex] + x

Multiply x by [tex]\frac{y}{y}[/tex] to create a common denominator

= [tex]\frac{x}{y}[/tex] + x × [tex]\frac{y}{y}[/tex]

= [tex]\frac{x}{y}[/tex] + [tex]\frac{xy}{y}[/tex]

= [tex]\frac{x+xy}{y}[/tex]

Using diagonals from a common vertex, the maximum number of triangles that will be formed is 5 triangles.

The given polygon is irregular heptagon (7 unequal sides).

The given polygon is irregular and the maximum number of triangles that will be Formed is explained as follows;

Alternatively, we can use the following formula;

number of triangles formed = 7 - 2 = 5 triangles

Thus, using diagonals from a common vertex, the maximum number of triangles that will be formed is 5 triangles.

Answer:

Step-by-step explanation:

Let the line to be found be Line 2

Given:

Line 1 :

y = 4x + 6

Since y = mx + b

We can substitute and find that the slope of Line 1 is 4

Therefore slope of Line 2 = (4)

Line 2:

Point - (1,6)

Slope - 4

Therefore: 6 = (4)(1) + b

So equating it we get : b = 2

Answer:

Two solutions: X = -5 and X = -0.5

Step-by-step explanation:

4x^2 + 22x + 10 = 0 // divide by 2

2x^2 + 11x + 5 = 0

delta = 11^2 - 4 * 2 * 5 = 121 - 40 = 81

sqrt(delta) = 9

x1 = (-11 - 9) / 4 = -5

x2 = (-11 + 9) / 4 = -0.5

Answer:

a) 0

Step-by-step explanation:

the equation of the slope (m) for a line from two points is given as (y2-y1)/(x2-x1)

we are given the points (3,-2) and (9,-2)

we can label the points:

x1=3

y1=-2

x2=9

y2=-2

now substitute into the equation:

m=(-2--2)/(9-3)

simplify

m=(-2+2)/6

m=0/6

m=0

the slope of the line is 0, which is option a

Hope this helps!
