It takes jill 2 hours to run 14.5 miles. At this rate how far could she run in 3 hours?
grin007 [14]

Answer:

She can travel 21.75 miles in 3 hours.

Step-by-step explanation:

Firstly, you have to find out how many miles can Jill travel in 1 hour. So you divide it by 2 :

2hr = 14.5miles

1hr \:  = 14.5 \div 2 \\ 1hr = 7.25miles

We have found out that she can travel 7.25 miles per hour. Next wr have to multiply it by 3 as the question says how far she run in 3 hours :

1hr = 7.25miles

3hr = 7.25 \times 3 \\ 3hr = 21.75miles

Which inequality has –12 in its solution set? A B C D x + 6 less-than negative 8 x + 4 greater-than-or-equal-to negative 6 x min
Vlad1618 [11]

Answer:

<u>The correct answer is D.  x + 5≤ - 4</u>

Step-by-step explanation:

Let's review which inequality has - 12 in its solution set, this way:

A. x + 6 less-than negative 8

-12 + 6 < - 8

-6 < - 8 Not correct

B. x + 4 greater-than-or-equal-to negative 6

- 12 + 4 ≥ - 6

- 8  ≥ - 6 Not correct

C. x minus 3 greater-than negative 10

- 12 - 3 > - 10

<u>- 15 > - 10 Not correct</u>

D. x + 5 less-than-or-equal-to negative 4

- 12 + 5 ≤ - 4

- 7 ≤ - 4 This is correct

<u>The correct answer is D.  x + 5≤ - 4</u>
