Consider the following formula used to estimate the height, h, of a seedling 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 seedling?A. w = 5h - (8/5) B. w = 5h - 8C. w = h/5 - 8D. w = h/5 - 8/5
Accepted Solution
A:
[tex]\bf h=\cfrac{1}{5}w+\cfrac{8}{5}\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{5}}{5(h)=5\left( \cfrac{1}{5}w+\cfrac{8}{5} \right)}\implies 5h=w+8\implies 5h-8=w[/tex]
