Nathan participated in a 5k race. He walked 1/4 of the way , jogged 3/5 of the way , and run 3/20 of the way

4.25 km (See Below)

Step-by-step explanation:

The question is:

How many kilometers did Nathan walk and jog?

Solution:

He walked 1/4th of 5 kilometer race

He jogged 3/5th of 5 kilometers race

Rest, he ran.

We need total km he ran and jog. That is (1/4) + (3/5)th:

So, we find 17/20th of 5, which is:

So, Nathan walked and jogged 4.25 km of the race.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

you can't solve x because it is 2 linear equation and you only have one equation
