The decimal number used to represent 5 out of 100 missed on her test is 0.95.
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.
Answer:
r = 11
Step-by-step explanation:
mDG and mGM must add up to mDM
Step 1: Set up equation
mDG + mGM = mDM
r + 5 + 3r - 14 = 35
Step 2: Solve for <em>r</em>
<u>Combine like terms:</u> 4r - 9 = 35
<u>Add 9 to both sides:</u> 4r = 44
<u>Divide both sides by 4:</u> r = 11
