$5x + 15 = 2x + 3 \\ 5x + 15 + 3 = 2x \\ 5x + 18 = 2x \\ 18 = 2x - 5x \\ - 3x = 18 \\ x = \frac{18}{ - 3} \\ \\ x = - 6$

Choose the best description for the real number 34 over 3.

dybincka [34]

Hello!

First of all let's eliminate the answers that do not make sense. For A. numbers are NOT irrational because they are a fraction. Numbers are also not irrational because they are a repeating number. C and D are both correct as fractions and terminating decimals are both rational numbers.

34/3≈11.33333333

By using a certain formula you can convert repeating decimals to a fraction. But most people know that .3333333 is 1/3. This gives us 11 1/3 as our answer. So what does it match? It is not a terminating decimal. It repeats but can be written as a fraction. Therefore our answer is C) Rational, because it is a fraction.

I hope this helps!

Donna can fold 400 shirts in an hour. At this rate, how many seconds will she take to fold 120 shirts?

borishaifa [10]

400 shirts in 1 hour, 60 seconds in 1 minute, 60 minutes in 1 hours, so 3600 seconds in an hour.

400/3600 = 120/x

400x= 432,000

x=1080 seconds
