# find the value of r so that the line that passes through (r,-5) and (3, 13) has a slope of 8. a. (-18/5) b. (3/4) c. 6 d. -141

Answer: Slope = Change in y/ Change in x.

8 = (13 - -5) / (3 - r)

8 = 18/(3 -r)

3 - r = 18/8

3 - r = 9/4

3  - 9/4 = r

3 - 2 and 1/4 = r

3/4 = r

r = 3/4   B.

Jules ran 2/3 miles. Miles ran 5/8 more than Jules. How many miles did Miles run?

2/3 is equivalent to 16/24
and 5/8 is equivalent to 15/24 miles
15/24+16/24= 31/24

31/24 simplifies to 1 6/24
Which simplifies down to 1 1/6

Miles ran 1 and 1/6 miles
Miles ran 15/24 . Have a good day and ask questions! :)

What two whole numbers is √29 between?
3 and 4

4 and 5

5 and 6

6 and 7

5and 6

Step-by-step explanation:

5² = 25

6² = 36

Therefore 29 is between 25 and 36.

This shows that sqrt of 29 is between 5 and 6

5 and 6

Step-by-step explanation:

Consider perfect square numbers either side of 29

25 < 29 < 36, thus

< < , that is

5 < < 6
