Perpendicular = Negative Reciprocal
-3 --> -1/3 ---> 1/3
Therefore it is C
Answer:
60$ on books with 15$ for music, subtraction
Step-by-step explanation:
So 1 would be 5r+20 and then the second one would be
First you need to get all variables on one side. You do that by multiplying the reciprocal of the fraction to everything.
N(5/1) x 1/5(5/1)=2/15(5/1)
5n=2/15 x 5/1
Then solve the multiplication problem
5n= 10/15
Then you should reduce the fraction
5n=2/3
Then divide both sides by 5
5n/5=N
2/3 divided by 5 =2/15
N=2/15
The first one is A and the second is either B or D I can’t decide
