First one is 64
second one is 64
third one is 64
so your last one is it because 32 * 32 is way higher than 64
100 = 30 + 10 + 10x
100 = 40 + 10x
-40 -40
60 = 10x
--- ----
10 10
6 = x
The equation is: 100 = 30 + 10 + 10x
The price of one cap is: $6
Answer:
x=−6 and y=7
Step-by-step explanation:
Step: Solve8x+5y=−13for x:
8x+5y=−13
8x+5y+−5y=−13+−5y(Add -5y to both sides)
