Joshua runs each day after school to train for his cross country team. He ran three miles the first week, six the second week, and nine the third week. If this pattern continues, how many miles will he be running during the fifteenth week of school?

He will be running 45 miles in the during the fifteenth week of school.

Step-by-step explanation:

Given: Joshua runs each day after school to train for his cross country team.

He ran 3 miles in first week, 6 miles in second week, 9 miles in third weeki.e. sequence will be  3, 6, 9 ,(multiple of 3.)

The number of miles he will be running during the fifteenth week of school = 15 x 3

=45

Hence, he will be running 45 miles in the during the fifteenth week of school.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
