V=(hπr^2)/3, π≈3.14, h=7, r=2
V≈29.3 cm^2
Answer:
y=2/3x-3
Step-by-step explanation:
using y=mx+c
since the intercept is negative,it affects the positive sign
Bill = 4b + 2.
Ron = 8b - 5.
Bill + Ron = (4b + 2) + (8b - 5).
= 4b + 8b + 2 - 5.
= 12b - 3.
That's the expression for the total number of blocks used by both Bill and Ron.
