I think you doubled them
ratio of dogs to cats=3:2
30 animals total
3+2=5 units
30=5unit
divide by 5
6=1unit
dogs=3 unit
6=1unit
times 3
18=3unit=dogs
18 dogs
Answer: a) 15 1/2 hours
Step-by-step explanation :
1/2 ×2=1. 1×4=4 1 1/2 ×1= 1 1/2 2×2=4. 2 1/2 ×2= 5
Add all answers and you have 15 1/2 hours.
36 ÷ 9 = 4
So.. 1% is 4 people
23 + 47 = 70%
70 × 4 = 280
Hope this helped :)
Let the number of yards she trimmed be t
She trimmed 5 more yards than she cut and she mad $415, so
20t+15(t-5)=415
We first distribute the second number so this equals
20t+15t-75=415
Then we add 75 to both sides, getting
20t+15t=490
This means that
35t=490
And we divide both sides by 35 to get
t=14
So, she trimmed 14 yards
