Question

on the last day of her summer tennis camp, linda helps her instructor sort through a basket of tennis balls to throw out the old ones. linda ends up throwing away 13 of the balls. she returns the remaining 42 balls to the basket. which equation can you use to find the total number of tennis balls t linda checks? \\(\frac{t}{13} = 42\\) \\(t - 13 = 42\\) \\(t + 13 = 42\\) \\(13t = 42\\) solve this equation for t to to find the total number of tennis balls linda checks. \\(\square\\) tennis balls submit

Explanation:

Step1: Identify the correct equation

The total number of tennis balls is \( t \). She throws away 13, so the remaining is \( t - 13 \). The remaining is 42, so the equation is \( t - 13 = 42 \).

Step2: Solve the equation for \( t \)

To solve \( t - 13 = 42 \), add 13 to both sides:
\( t - 13 + 13 = 42 + 13 \)
\( t = 55 \)

Answer:

The correct equation is \( t - 13 = 42 \), and the total number of tennis balls is \( \boldsymbol{55} \).
