Each piece of cake costs $.56 ($.55875)
I divided 8.94 by 16 to find how much one piece costs.
1. 3y=27
2. x-4=3
3. p+8=17
4. 1/2q=14
Tricky one because they're asking for C not x.
2x + 2x + 6x = 180
10x = 180
x = 18
C = 2x = 36
Last one
You have to divide 128 by 8 and you will get 16. So the answer is 16
Answer:
B
Step-by-step explanation:
Combine like term.
Hers 7x and (-5x) are like terms
7x + 4x² - 5x = 7x - 5x + 4x²
= 2x + 4x²
