To determine this you could think of it in a couple ways.
1. If it takes 1/10 of a bag of fertilizer to put around 1 tree, he can fertilize 10 trees with 1 bag because there are 10 groups of 1/10 in a bag. Take 10 x 40 because there are 40 bags and get 400 trees to be fertilized.
2. You can divide 40 by 1/10 as the other strategy.
This is the same as 40 x 10/1.
Also equaling 400 trees that can be fertilized.
Get yo as.s up and go finish your test, I know it’s hard but you got this believe in yourself bestie :) love ya
Answer:
<h3>a = 3gh+9h</h3>
Step-by-step explanation:
![3+g = \frac{a}{3h} \\\\Cross\:Multiply\\\\3h(3+g) = a\\9h +3gh = a\\\\a = 3gh+9h](https://tex.z-dn.net/?f=3%2Bg%20%3D%20%5Cfrac%7Ba%7D%7B3h%7D%20%5C%5C%5C%5CCross%5C%3AMultiply%5C%5C%5C%5C3h%283%2Bg%29%20%3D%20a%5C%5C9h%20%2B3gh%20%3D%20a%5C%5C%5C%5Ca%20%3D%203gh%2B9h)
