I'll give it a " shot "

Define units for the additional practice time and the time spent working on shooting skills.

hours and hours

Then enter a variable for the additional practice time. . . (additional to the 18 hours)

x -- this is the expression for Additional Practice Time.

. . .and use this variable to write an expression for the time spent working on shooting skills.

\(\frac34\)(x + 18) -- this is the expression for Time Spent Shooting.

Question 1

For Additional Practice Time, we are given 51

So Time Spent Shooting = \(\frac34\)(51 + 18) , which = 51.75

Question 2

For Time Spent Shooting, we are given 55.5

Additional Practice Time = x and \(\frac34\)(x + 18) = 55.5

\(\frac34\)(x + 18) = 55.5 Multiply both sides of this equation by 4/3

x + 18 = 74 Subtract 18 from both sides

x = 56 = Additional Practice Time

Question 3

For Additional Practice Time, we are given 46

So Time Spent Shooting = ..... (Can you finish it??)
