Mikayla is training for a half-marathon. at the beginning of her training, she is able to run 2 miles without stopping. her goal is to increase her distance by three quarters of a mile each week. a) write an equation to represent the number of miles mikayla is able to run after each week. define your variables.

Alright, lets get started.

At the beginning of her training, she is able to run 2 miles without stopping means 2 will be in the addition when we will write the equation for her running miles.

Her goal is to increase her distance by three quarters of a mile each week.

Means in first week, she will add the distance = miles

Suppose she runs x weeks, so shee will add distance =

So, suppose she runs total number of miles = d, then

Where d is total numer of miles she runs

x is number of weeks    :   Answer

Hope it will help :)

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

answer: 4 (:
