Justin jogged for four days in a row. He jogged 2 miles the first day. On the second day, he jogged 75% of the distance he jogged the first day. On the third day, he jogged 1.5 miles more than the distance he jogged the first day. If Justin jogged a total distance of 9.25 miles, how many miles did he jog on the fourth day?

2.75 miles jogged on the fourth day

Step-by-step explanation:

Justin jogged 2 miles on the first day.

On the second day he jogged 75% of 2 miles. To find 75% of 2 miles we need to divide by 100 and multiply by 75.

2 / 100 = 0.02 x 75 = 1.5 miles jogged on the second day. (3.5 miles jogged in total so far)

On the third day he jogged 1.5 miles more than the last day:

1.5 + 1.5 = 3 (6.5 miles jogged so far)

9.25 total miles were jogged, meaning that we will need to subtract 6.5 from 9.25 to get the

9.25 - 6.5 = 2.75 miles jogged on the fourth day

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
