HELP PLEASE!!! Maia walks 12 miles. Then she walks 1/4 of that distance. select ALL of the expressions that represent the total distance she walks.

Answers

Answer:

1, 2, and 3

Step-by-step explanation:

The expressions that represent the total distance she walked are 12 + 0.5 × 12, 12(1 + 0.5), and 12×1.25.

What is a fraction?

A fraction is a part of the whole represented by a/b, where a and b are any integers.

Given that, Maia walks 12 miles and then 1/4 of 12 miles.

The total distance is:

12 + 1/4 of 12

= 12 + 1/4×12

= 12 + 0.5 × 12

=12(1 + 0.5)

= 12×1.25

= 15

Hence, the expressions that represent the total distance she walked are 12 + 0.5 × 12, 12(1 + 0.5), and 12×1.25.
