To model Gracie's running, write an equation where she runs 23 miles in the first half and a total of 50 miles by the end of the semester. The correct equation is: $x-23=50$ .

STEP 1

Assumptions
1. Gracie runs a total of 23 miles during the first half of the semester.
2. The total miles run by the end of the semester is 50 miles.
3. We need to find the number of miles run in the second half of the semester.
4. We will denote the number of miles run in the second half of the semester as $x$ .
5. The equation will represent the sum of the miles run in the first half and the second half of the semester to equal the grand total.

STEP 2

Let's denote the number of miles Gracie runs in the second half of the semester as $x$ .

STEP 3

We know that the total miles run by Gracie at the end of the semester is 50 miles.

STEP 4

We also know that Gracie runs 23 miles during the first half of the semester.

STEP 5

To find the total miles run by the end of the semester, we add the miles run in the first half to the miles run in the second half.

STEP 6

Write the equation that represents the total miles run by the end of the semester.
$23 + x = 50$

STEP 7

This equation shows that when we add the miles run in the first half of the semester (23 miles) to the miles run in the second half of the semester ( $x$ ), we get the grand total (50 miles).

STEP 8

Therefore, the correct equation to model this situation is:
$23 + x = 50$
The correct answer is A: $23+x=50$ .

STEP 2

Let's denote the number of miles Gracie runs in the second half of the semester as x x x.

STEP 3

We know that the total miles run by Gracie at the end of the semester is 50 miles.

STEP 4

We also know that Gracie runs 23 miles during the first half of the semester.

STEP 5

To find the total miles run by the end of the semester, we add the miles run in the first half to the miles run in the second half.

STEP 6

Write the equation that represents the total miles run by the end of the semester.23+x=5023 + x = 5023+x=50

STEP 7

This equation shows that when we add the miles run in the first half of the semester (23 miles) to the miles run in the second half of the semester (x x x), we get the grand total (50 miles).

STEP 8

Therefore, the correct equation to model this situation is:23+x=5023 + x = 5023+x=50The correct answer is A: 23+x=50 23+x=50 23+x=50.
