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 1.3 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}{1.3} = 42\\) \\(t - 1.3 = 42\\) \\(t + 1.3 = 42\\) \\(1.3t = 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

Linda throws away 13 balls, so the remaining balls are total balls \( t \) minus 13, which equals 42. So the equation is \( t - 13 = 42 \).

Step2: Solve the equation for \( t \)

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

Answer:

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