Answer:

Choices C and D

Step-by-step explanation:

The most simplest way is just to solve each one and see which two have the same answer as the first expression.

But you could also see that both of the \frac{4}{7} are going to cancel each other out so you are left with -\frac{8}{9} +\frac{9}{8}  which is also choice C.

For choice D I distributed the negative one to the insides of the parenthesis that left me with -\frac{4}{7}-\frac{8}{9}+\frac{4}{7} +\frac{9}{8}  which is the same expression as the first one.

elena-14-01-66 [18.8K]

Solution:

The gas can is filled at the rate of 320 cubic inches per minute.

The can is 10 inches long, 8 inches wide, and 12 inches high.

So volume of the can=10 in*8 in *12 in

\text{Volume of can }=960  \ in^3\\

Time required to fill the can=\frac{960}{320}=3  \ minutes\\

Hence Time required to fill the can =3 minutes.

a line with the slope of -2 passes through the point (1,7) what is the closest point on the line above (1,7) which has a whole n
deff fn [24]
The closest point above on this line is (0,9)

You can find this by using the rise over run method. Since the slope is -2, we can move to the next whole number point by observing the fraction 2/-1.

Rise = 2
Run = -1

If you start on the point (1,7) and rise two, it will bring you to (1,9), then you have to move back one space (or run) to (0,9).
