WITCHER [35]

Answer:

The answer to your question is 7 times

Step-by-step explanation:

Data

Percent of accuracy = 35%

Times she is at bat = 20

Times she hit the ball = ?

Process

1.- Use proportions to solve this problem

20 times will be the 100%  because is the total number of times she is at bat.

                     20 times ------------------ 100%

                       x            ------------------   35%

                       x = (35 x 20) / 100

                       x = 700 / 100

                       x = 7

2.- Conclusion

From 20 times she is at bat, she will hit the ball 7 times.

What inverse operation would you use to verify the following equation? 102/3 = 34
Yakvenalex [24]
You would just change the division to multiplication and because three cancels out the 3 that 102 is divided by it would take the 3 away from the left side. then you would also multiply 3 on the other side to make them equal then the equation would be 102 = (34)3
