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.
now, the so-called standard form, is moving the variables to the left-hand-side, sort them in descending order according to their exponents, and usually alphabetically some, so the "x" is left of the "y" and so on
-x+y=-4
Answer:
-1/3
Step-by-step explanation:
y=mx+b where m=slope and b=y-intercept.
