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
Answer:
y=22 and x=34Answer:
Step-by-step explanation:
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

You will need 6 cups of sugar.
Step - by - Step Explanation
What to find? <em>The number of cups of sugar needed to make a cake with 12 cups of flour.</em>
<em />
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

x =6
Hence, you will need 6 cups of sugar.
