Answer:
these are supplementary
and x = 50
Step-by-step explanation:
one straight line = 180 degrees
there are only two angles making up this 180 degree line, so by definition they are supplementary
76 + 2x + 4 = 180
80 + 2x = 180
2x = 100
x = 50
3/6 (r-7) =1 The answer is r=7

Answer:
There are 28 more dogs than cats at the animal shelter.
Step-by-step explanation:
If the ratio of dogs to cats at an animal shelter is 3:1, that means there are 3 dogs for every 1 cat.
The way I think about it is I try multiplying every number by 3 and 1, kind of like process of elimination.
After using every number from 1-13, I finally got to 14. Now, 3 x 14 = 42 and 1 x 14 = 14. Add 42 + 14 and you will get 56.
So there are 42 dogs and 14 cats at the animal shelter.
However, it is asking for how many more dogs than cats there are, so you have to subtract 42 - 14 and the answer is 28 more dogs than cats.
