Mrs. Fields bought a sapling from a tree farm nursery and observed a linear growth of the sapling over a period of 6 months. She found the height of the sapling, H centimeters, and the time, t months is related by the linear equation H=2(4+3t)

Question

a) write an equation for t in terms of h

C) find h when t=6

D) how many months until the height of the sapling is 29 centimeters?

Answer 1

a) h = 8 + 6t
6t = h-8
t = (h-8)/6

c) when t = 6
h = 8 + 6(6) = ....

d) when h = 29

29 = 8 + 6t
21 = 6t
t = 21/6 = 3.5

it would take 3.5 months
