<u>Answer:</u>
- There are 39 cats and 83 dogs.
<u>Step-by-step explanation:</u>
<u>We know that:</u>
- D + C = 122
- D = 5 + 2C
- C = Number of cats
- D = Number of dogs
<u>Work:</u>
- D + C = 122
- => 5 + 2C + C = 122
- => 5 + 3C = 122
- => 3C = 122 - 5
- => 3C = 117
- => C = 117/3
- =>

- => D + C = 122
- => D + 39 = 122
- => D = 122 - 39
- =>

Hence, <u>there are 39 cats and 83 dogs.</u>
Hoped this helped.

Answer:
d + c = 122
d - 5 = 2c
so same as saying
2d + 2c = 244
we plug in for 2c
2d + d - 5 = 244
2d + d = 249
3d = 249
d = 249 / 3
d = 83
since d - 5 = 2c
83 - 5 = 2c
78 = 2c
c = 39
there are 39 cats and 83 dogs
39 + 83 = 122

Answer:
26
Step-by-step explanation:
Okay so first, let's write out an equation:
36.26/49 = x/100
Then, multiply both sides by 100 to get the x isolated.
x = 74
100-74 = 26
So the percent decrease is 26
The equation would be 8 times the amount of pounds bought equals the amount paid.
