Step-by-step explanation:
<u>Question 43</u>
- Let cheese pizza be c and mushroom pizza be m
- 3c + 4m = 12.50
- 3c + 2m = 8.50
Subtract Equation 2 from Equation 1.
- 3c + 4m - 3c - 2m = 12.50 - 8.50
- 2m = 4.00
- m = $2.00
- <u>(2) $2.00</u>
Answer:
600
Step-by-step explanation:
set x as the number
x0.10 = 60
x = 60/0.10
x = 600
The first one has a negative. You shouldn't have a negative isolated variable,
-x = 5y -1, Multiply everything by -1,
x = -5y + 1,
For the second one, you isolate the x,
x + 2y = 13, subtract 2y from both sides,
x = 13 - 2y.<span />
