If 2A:3B =5:6 and 3B:2C =36:15, then find A:C

Step-by-step explanation:

2A:3B

= 5:6

3B:2C

= 36:15

A:C

= ?:?

2A/3B x 3B/2C

=5/6 x 36/15

=1/1 x 6/3

=1/1 x 2/1

=2

3B and 3B got canceled

For 2A and 2C, the 2 in front of A and C, got canceled as we are cross multiplying.

So I think the answer is

A:C

=1:1     ??

My answer could be wrong.

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
