The answer is (20,0). We can determine the sum of two vector points by adding x1 to x2 and y1 to y2. This is like adding integers, the only difference is the answer is in vector form. In here, we have (x,y). x = 7+13 and y = 5+(-5). that is why we have the (20,0) as the answer.
5.5/12 = x/60
One hour/ 12 minutes = 5
5.5•5=27.5

By a 6th grader-----------------------------------------------------------------------------------------------find # that is a common multiple of 2 and 7 - the denominators ( 14 )
then do:
denominator stays same - if improper fraction change to mixed #
1 times 7 = 7 + 3 times 2 = 6
2 times 7 = 14 7 times 2 = 14
6 + 7 over 14 is 13 over
14
if possible and needed - change to simplest form
Answer:
The BEST value would be 70 brushes.
Step-by-step explanation:
First, get all the values per brush for all brushes listed.
20 / 11.80 = $1.70
35 / 17.15 = $2.04
50 / 27.50 = $1.81
70 / 45.50 = $1.53
80 / 36.00 = $2.22
So, as you can see we have the values for what a single brush would cost from each selection. 70 brushes would be the BEST value.
