A=12
120% of a =80% of b
120%a = 80%b
120a/100 = 80b/100
Divide through by 100
120a = 80b
Divide through by 80
120a/80 = b
But a=12
120x 12/80 = b
18 = b
b = 18
a+b = 12 + 18 = 30
I believe it's A I really hope that's right
Answer:
One Solution: 3
Step-by-step explanation:
5x - 9 = -24 + 10x
Subtract 5x from both sides. -9 = -24 + 5x
Add 24 to both sides. 15 = 5x
Dived 15/5. 3 = x
Answer:
$7
because theres 4 quarters in a mile so one mile would equal to $2 bc
0.50 x 4 = $2
and you have to go 2 miles so
$2 + $2 = $4
then you add the the cost of the taxi so
$4+ $3
= $7
