Answer:
Step-by-step explanation:
erasers=e
pencils=p
3e+5p=7.55 ...(1)
6e+12p=17.40
divide by 2
3e+6p=8.70 ...(2)
(2)-(1) gives
p=8.70-7.55=1.15
from (1)
3e+5(1.15)=7.55
3e+5.75=7.55
3e=7.55-5.75
3e=1.80
e=1.80/3=0.60
cost of 1 eraser=$0.60
cost of 1 pencil =$1.15
All real numbers because it’s a function that has no limit

Answer:
153 cubic feet
Step-by-step explanation:
V = kha .........where h is height and a area and V is volume
92 = k * 12 * 23
k = 92/(12*23) =1/3
if k, constant is 1/3
volume =1/3 * 17 * 27
=153 cubic feet
