Write the mathematical sentence or a grammatical sentence as a mathematical one. Mount Mo is 5323 feet tall. Dawn climbed it in 5 days. She climbed 821 feet on the last day. How many feet did she climb in the first four days?

Respuesta :

Let the number of feet climed in the first four days be x.

Since she climbed 821 feet on the last day, the following sum gives the total feet climed:

[tex]821+x[/tex]

Equate this sum to 5323:

[tex]821+x=5323[/tex]

Next solve for x in the equation:

[tex]undefined[/tex]
