Question

15. Aime, Seamus and Shane were discussing how long it took them to complete their

Answer 1

Answer:

C(2) + (C- 45) + C

Step-by-step explanation:

Let's use these variables to represent Aime, Seamus, and Shane in our expression:

A = Aime

C = Seamus

S = Shane

We know that Aime spent twice as long as Seamus did while doing homework. Therefore we would add this to our expression:

C(2)

We multiply Seamus' time by 2 because Aime spent twice as long doing school. That means we have to multiply.

Now, to represent Shane's time spent doing school, we would need to make the equation look like this:

C(2) + (C - 45)

We subtract 45 from C (Seamus' time spent doing HW) because Shane spent 45 minutes less than Seamus did doing HW.

Finally, we just need to represent Seamus' time:

C(2) + (C - 45) + C

We add Seamus' time at the end of the expression since we are trying to figure out the total amount of time Aime, Shane, and Seamus spent doing HW.

I hope this helps!

Answer 2

Answer:

x + 2x + (x - 45)

Step-by-step explanation:

seamus is x

aime is twice seamus so multiply x by 2

shane did it 45 less than seamus so subtract by 45
