It took Joan 10 hours to walk a 30-mile trail. How long did it take her to walk 9 miles at the same speed?

3 hours

Step-by-step explanation:

1. We first take how much miles she goes and the hours and divide.

30 miles/10 hours= 3 miles/ per 1 hour

2. Now we take that and set up an equation to cross multiply

9/x=3/1

In 3 hours she would have gone 9 miles

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

answer: answer is c!

ok i got to organize the

3/15 and 12/55

3*

aha

3*4 equals 12 but not

a: no

b:

8/24 12/35

no

gautie

it's c

5/18 = 25/90

5*5=25

18*5 = 90

hope that you!

one more happy customer!
