Question

consider the following formula used to estimate the height, h, of a seedling after w weeks since planting: h=(1/5)w +(8/5)

Answer 1

Option b
`w=5h-8`

Explanation:

The complete question is

Consider the following formula used to estimate the height, h, of a seeding after w weeks since planting

h=(1/5)w + (8/5)

which of the following represents the formula that could be used to find the number of weeks since planting using the height, h, of the seeding? Select one answer.

(a) w = 5h - (8/5)

(b) w = 5h - 8

(c) w = (h/5) - 8

(d) w = h/5 - 8/5

we have

`h=(1)/(5)w+(8)/(5)`

Solve for w

That means ----> Isolate the variable w

Multiply by 5 both sides to remove the fraction

`5h=w+8`

subtract 8 both sides

`5h-8=w+8-8`

`5h-8=w`

Rewrite

`w=5h-8`
