To find: number of baskets Cliff, Lyle and Kyle shoot
Answer to Problem 9P
Cliff shoot
Explanation of Solution
Given information: “Lyle shot three times as many baskets as Cliff”, “Kyle shot 12 more baskets than Cliff” and “Lyle and Kyle shot the same number of baskets”
Concept Involved:
Assign variable for the unknown that we need to find.
Use the keywords in the statement to rewrite the statement to meaningful math equation.
“is” means =
“more than” means +
“three times” means 3×
Solve the equation by getting the variable in one side of the equation and undoing whatever is done to it by performing reverse operation.
Calculation: Assign variable for the unknown that we need to find
Let x represents number of baskets Cliff shoot
Write an expression to represent number of baskets Lyle shoot using the sentence “Lyle shot three times as many baskets as Cliff”
Write an expression to represent number of baskets Kyle shoot using the sentence “Kyle shot 12 more baskets than Cliff”
Replace the keywords to get an equation representing the sentence given “Lyle and Kyle shot the same number of baskets”
In the process of getting x in one side of the equation subtract x on both sides
Combine like terms on both sides
Divide 2 on both sides of the equation
Simplify fraction on both sides of the equation
Substitute 6 for x in the expression
Substitute 6 for x in the expression
Conclusion:
Cliff shoot
