Respuesta :

Answer is A

12+x

____. =0.70

24+x

Answer:

A

Step-by-step explanation:

Currently, Andy has a winning record of 50%.

12 /24  = 0.50

To determine a winning record of 70%: add x matches to 12, x matches to 24, and set equal to 0.70.

12 + x /24 + x  = 0.70

x = 16

Therefore, Andy would need to win 16 matches in a row.
