consider the following formula used to estimate height, h, of a seedling after w weeks since planting:
[tex]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}[/tex]

Answer:

Option B. [tex]w=5h-8[/tex]

Step-by-step explanation:

we have

[tex]h=(\frac{1}{5})w+(\frac{8}{5})[/tex]

Solve for w

That means ----> isolate the variable w

Multiply by 5 both sides to remove the fraction

[tex]5h=w+8[/tex]

subtract 8 both sides

[tex]5h-8=w+8-8[/tex]

[tex]5h-8=w[/tex]

Rewrite

[tex]w=5h-8[/tex]
