Question

denice buys a pack of 79 highlighters. she gives 9 to her teacher and shares the remaining highlighters equally between herself and 4 friends.
must be an equation
an equation shows two equal expressions on either side of an equal sign.
(7(-9) ÷ 5 = 14)

Explanation:

Step1: Find remaining highlighters

Total highlighters: 79. Given to teacher: 9. Remaining: \( 79 - 9 \).

Step2: Determine number of people

Denice + 4 friends: \( 1 + 4 = 5 \) people.

Step3: Set up equation

Let \( x \) be each person's share. Total shared: \( 5x \). Remaining = shared, so \( 5x + 9 = 79 \) (or \( (79 - 9) \div 5 = x \), solving gives \( x = 14 \)). Correct equation: \( (79 - 9) \div 5 = 14 \) (or \( 5x + 9 = 79 \), solving \( x = 14 \)).

Answer:

The correct equation is \( (79 - 9) \div 5 = 14 \) (or \( 5x + 9 = 79 \) with \( x = 14 \)). The given \( (7(-9)\div5 = 14) \) is incorrect; the correct one uses 79, not 7, and subtraction, not multiplication of -9.
