Answer:
Step-by-step explanation:
The area of a rectangle is given by 
, where 
is the length of the rectangle and 
is the width of the rectangle. Therefore, the area of a 20 x 15 rectangle is equal to 
.
Since one bag of fertilizer covers 30 square feet, the farmer needs 
bags of fertilizer.
A rate is a special ratio in which the two terms are in different units. A rate is a little bit different than the ratio, it is a special ratio. For this case, the rate would have units of miles per minutes. We calculate as follows:
rate = 36 miles / 45 min = 0.8 miles per min
distance traveled = 0.8 miles per min ( 60 min ) = 48 miles
Answer:
16/25
This is because you have to make it into a percent which is 64% then you have to do 64/100 and simplify it.
It's not too difficult!! your absolute value expression is already isolated, so now you have to set it up like this:
5v + 3 > -9
and
5v + 3 < 9 (opposite of original, flip inequality symbol)
this is because absolute value only tells you how many units away a number/expression is from 0 on a number line. it could go to the left, or the right--negative, or positive. so you have to allow for both equations
from there, just solve them like normal inequalities
5v + 3 > -9 ... subtract 3
5v > -12 ... divide by 5
v > - 12/5
5v + 3 < 9 ... subtract 3
5v < 6 ... divide by 5
v < 6/5
so, v must be greater than -12/5, and less than 6/5
