Answer:
x = 18
Step-by-step explanation:
Given:
Finding x for which 3b = 5a:
- 3(4x - 7) = 5(2x + 3)
- 12x - 21 = 10x + 15
- 12x - 10x = 15 + 21
- 2x = 36
- x = 36/2
- x = 18
Answer:
4:7
Edit: I just saw the multiple choice options, in this case the right answer is:
<h2>
8:14</h2>
but they're both equal
Step-by-step explanation:
The ratio you are looking for is
freestyle laps : (freestyle + butterfly) laps
so:
8 : (6+8)
8:14
Divide by 2 to simplify
4:7
