Running An athlete runs an equal distance 4 days a week. The other 3 days of the week, he runs a total of 13 miles. Write an equation to represent the total number of
miles run in a week R and the number of miles x run each of the 4 days. If the athlete ran 45 miles last week, how far did he run each of the first 4 days?
Which equation represents the total number of miles run in a week R and the number of miles x run each of the 4 days?
OA 4=R+13x
OB. R=4x+13
OC. 4=Rx+13
OD. R=4+13x
He ran miles each of the first 4 days.
