Answer:omg x is 7 y is 8 and part c is shut up
Step-by-step explanation:
15 inches of wire costs 0.75......0.75/15 = 0.05 per inch
for 11 inches......0.05 * 11 = $ 0.55 <===
F = k x
15 = k *10
k = 1.5
check:
24 = 1.5 x
x = 16 sureenough
so 1.5 oz/inch
= 1/1.5 inches/oz = 2/3 = 0.6666.... in/oz
Answer = 4 CDs
20% of 20 = 4
60% of 20 = 12
4 + 12 = 16
20 - 16 = 4
