Gary exercises 1.75 hours on mondays, wednesdays, and saturdays. how many weeks will it take gary to exercise a total of 21 hours?

For this case, the first thing we must do is define variables.

We have then:

x: number of days

y: total hours

The equation modeling the problem is given by:

Substituting for y = 21 hours we have:

From here, we clear the value of x:

It takes Gary 12 days to train 21 hours.

We know that Gary trains 3 days a week.

Therefore, the number of weeks is given by:

it will take Gary 4 weeks to exercise a total of 21 hours

the correct answer is 5 6 and 7

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
