Solve the system. y= 22 – 10x + 15 y=-10

Yuliya22 [10]

I will try to solve your system of equations.

y=22;−10x+15y=−10

Step: Solvey=22for y:

Step: Substitute22foryin−10x+15y=−10:

−10x+15y=−10

−10x+(15)(22)=−10

−10x+330=−10(Simplify both sides of the equation)

−10x+330+−330=−10+−330(Add -330 to both sides)

−10x=−340

−10x

−10

−340

−10

(Divide both sides by -10)

x=34

y=22 and x=34Answer:

Which expression is equivalent to 5(x + 7)?

larisa86 [58]

You need to multiply both numbers inside the parentheses by 5:

5 times x = 5x
5 times 7 = 35

So your answer is B. 5x + 35

Q Searchmatics Gr 7)I need 4 cups of flours and 2 cups of sugar to make a cake. How many cups of sugar do I need if Ihave 12 cup

Ede4ka [16]

You will need 6 cups of sugar.

Step - by - Step Explanation

What to find? The number of cups of sugar needed to make a cake with 12 cups of flour.

Given:

Cups of flours = 4

Cups of sugar = 2

Cups of flour =12

Let x be the number of cups of sugar needed to make a cake with 12 cups of flour.

Using proportion;

4 cups of flour = 2 cups of sugar

12 cups of flour = x

Cross - multiply

4x = 24

Divide both-side of the equation by 4

$\frac{\cancel{4}x}{\cancel{4}}=\frac{24}{4}$

x =6

Hence, you will need 6 cups of sugar.
