Question

1. janeens mother is 47. she is 26 years older than janeen. which equation can be used to find janeens age? a. ( j + 26 = 47 ) b. ( 26j = 47 ) c. ( j - 26 = 47 ) d. ( 47j = 26 ) 10. quentin bought 6 new tennis balls. if he now has a total of 18 tennis balls, how many did he start with? f. 9 g. 12 h. 21 i. 24

Explanation:

Question 9

Let \( j \) be Janeen's age. Her mother is 26 years older than her and her mother's age is 47. So Janeen's age plus 26 equals her mother's age. So the equation is \( j + 26 = 47 \).

Step 1: Define the variable

Let \( x \) be the number of tennis balls Quentin started with.

Step 2: Set up the equation

He bought 6 new ones and now has 18. So the equation is \( x + 6 = 18 \).

Step 3: Solve for \( x \)

Subtract 6 from both sides: \( x = 18 - 6 \)
\( x = 12 \)

Answer:

A. \( j + 26 = 47 \)
