Answer:
3/5=12/20
12/16=6/8
Step-by-step explanation:
If you are trying to figure out how much it will cost:
8 x 4 = 32
Cost of gas = $32
The first answer is going to be 15.42 (so b) and the second is going to be 10.67 (so a)
I think i am doing this right i am not sure. First you need to add up all the sides (100+38+22+15) it would equal 175 then you need to subtract it from 360 and get the missing value (x) then the answer would be 185
