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

Answer:

Option b $w=5h-8$

Step-by-step 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

$h=\frac{1}{5}w+\frac{8}{5}$  

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

$w=5h-8$
