Answer: 2

Work: Okay, this is simple, but needed to be taken one step at a time. First, you need to get x by itself, so you add the nine on both sides, canceling on the side it's currently on. So, the new equation is -3x = -6. To get the x by itself even more, we divide -3 on both sides, and again, cancelling it on the side it's currently on. So, the answer is x = 2. I hope this helps, and stay safe! :)

Which fraction is equivalent to 2/5? <br> A. 4/10 <br> B. 2/10 <br> C. 1/2 <br> D. 4/6

Lelechka [254]

Hey there James!

So, just remember, 2/5 is almost half of 1.

When it is almost half of 1, this means that it would have to be 2.5/5

This would mean that 4/10 would be your answer, because it is almost half of 1 also.

Hope this helps.

An algebra book weighs 6 oz less

Mashcka [7]

Answer:

Algebra book weighs 24 oz

Grammar book weighs 15 oz

Step-by-step explanation:

algebra = x and grammar = y

x = 2y-6

5x = 8y

5(2y-6) = 8y

10y - 30 = 8y

2y - 30 = 0

2y = 30

y = 15

x = 2(15)-6

x = 30-6

x = 24
