Question

consider the following formula used to estimate height, h, of a seedling after w weeks since planting:
$h=(\frac{1}{5})w+(\frac{8}{5}) which of the following represents the formula that could be used to find the number of weeks since planting using height, h, of the seedling? \\A. w=5h-\frac{8}{5} \\B. w= 5h-8\\C. w= \frac{h}{5} -8\\D. w=\frac{h}{5} -\frac{8}{5}$

Answer 1

Answer:

Option B. $w=5h-8$

Step-by-step explanation:

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

$w=5h-8$
