Answer:

x = -2

Step-by-step explanation:

3(5x + 2) = 2(3x - 6)

Expand the brackets.

15x + 6 = 6x - 12

Isolate the unknown variable x.

15x - 6x = -12 - 6

Evaluate.

It takes 1 1/3 hours to set up 1/3 of an hour to run and 2/3 of an hour to verify the results. How many hours will it take to co

liraira [26]

Answer: It will take $\frac{7}{3}$ of an hour to complete the test.

Step-by-step explanation:

We need to convert the mixed number $1\ \frac{1}{3}$ to an improper fraction:

$1\ \frac{1}{3}=\frac{(1*3)+1}{3}= \frac{4}{3}$

Now, we need to make the following add the fractions in order to calculate how many hours will it take to complete the test. Then, we get:

$\frac{4}{3}+\frac{1}{3}+\frac{2}{3}=\frac{4+1+2}{3}=\frac{7}{3}$

Therefore, it will take $\frac{7}{3}$ of an hour to complete the test.
