Question

The goal for the three girls was to run a total of 7 miles today. Create a equation using x, to represent the number of miles still remaining that the girls need to run together to meet their goal.

Answer 1

The equation to represent the number of miles still remaining that the girls need to run together to meet their goal can be written as x = 7 - (miles run by girl 1) - (miles run by girl 2) - (miles run by girl 3).

Step-by-step explanation:

The equation to represent the number of miles still remaining that the girls need to run together to meet their goal can be written as:

x = 7 - (miles run by girl 1) - (miles run by girl 2) - (miles run by girl 3)

Here, x represents the number of miles still remaining to reach the goal of 7 miles. You need to subtract the total miles run by each girl from 7 to find the remaining miles. For example, if girl 1 ran 2 miles, girl 2 ran 3 miles, and girl 3 ran 1 mile, the equation would be:

x = 7 - 2 - 3 - 1

Calculating this, we get:

x = 7 - 2 - 3 - 1 = 1 mile
