Q. On the last day of her summer tennis camp, Kathleen helps her instructor sort through a basket of tennis balls to throw out the old ones. Kathleen ends up throwing away 15 of the balls. She returns the remaining 57 balls to the basket.Which equation can you use to find the total number of tennis balls t Kathleen checks?Choices:(A) 15t=57(B) t+15=57(C) t−15=57(D) 15t=57Solve this equation for t to to find the total number of tennis balls Kathleen checks.____ tennis balls
Define total number of balls: Let's define the total number of tennis balls that Kathleen checks as t. Since Kathleen throws away 15 balls and is left with 57 balls, we can express the relationship between the total number of balls and the remaining balls with the equation t−15=57. This is because the total number of balls minus the 15 balls thrown away should equal the 57 balls that are left.
Solve equation for total: Now, we need to solve the equation t−15=57 for t to find the total number of tennis balls Kathleen checks. To do this, we add 15 to both sides of the equation to isolate t on one side.t−15+15=57+15t=72
Check solution: We should check our solution to ensure there are no math errors. If we substitute t with 72 in the equation t−15=57, we get:72−15=5757=57This is a true statement, so our solution is correct.
