How long will it take you to ski a distance of 24 miles at a speed of 6 miles per 30 minutes? *

120 minutes or 2 hours

Step-by-step explanation:

one way to solve it would be to get the distance traveled each 1 mile

6 miles = 30 minutes

6 6

1 miles * 24 = 5 minutes * 24

24 miles = 120 minutes or 2 hours

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
