Sure. So we have -9x, and then we can distribute the negative, just as we would do with a number. That gives us -9x-17-7x. We can combine the -9x and -7x to get -16x. Therefore, our answer is -16x-17. Hope this helped!

Answer:

7 miles / hour

Step-by-step explanation:

t (time) = 1/2 hour

r (rate) = ?

Formula

r = d/t

Solution

The easiest way to do this is to change the fractions to decimals.

t = 1/2 = 0.5 hours

r = 3.5 / 0.5

r = 7 miles per hour.

lora16 [44]
In order to answer this question let's suppose,
Joe is x miles from the beginning and y miles from the end. These assumptions are necessary to answer further:

Now,
x=2y
x+y=30
plugging in x=2y in the above equation
2y+y=30
3y=30
y=10

Hence, according to our calculations, Joe has to hike 10 miles further
