Answer:
Option H
Step-by-step explanation:
Perimeter of rectangle= 2(length) +2(width)
100= 2(5a -22) +2[½(a +1)]
Expand:
100= 2(5a) +2(-22) +a +1
100= 10a -44 +a +1
Simplify:
100= 11a -43
+43 on both sides:
11a= 100 +43
11a= 143
Divide both sides by 11:
a= 143 ÷11
a= 13
Thus, option H is correct.

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.
