B. 1/4(n - 64)
Multiplying n and -64 by 1/4 leaves you with 1/4n - 16, the original equation.
Answer:
y+mx+b
Step-by-step explanation:
10 cheese pizzas
use simple ratio, 3:2 (3 pepperoni for every 2 cheese)
to make the ratio bigger, we substitute the "3" pepperoni for "15" pepperoni. then take the new amount, 15/3 original, you get 5. then multiply the 2 original cheese pizzas by that 5, and you get 10 cheese pizza's.
hope that helps
we have
Solve for c--------> that means that clear variable c
so
Divide by 
both sides
Adds 
both sides
Multiply by 
both sides
![a[(R/5)+0.3]=c](https://tex.z-dn.net/?f=a%5B%28R%2F5%29%2B0.3%5D%3Dc)
so
![c=a[(R/5)+0.3]](https://tex.z-dn.net/?f=c%3Da%5B%28R%2F5%29%2B0.3%5D)
therefore
<u>the answer is</u>
