Answer:

x =  \frac{3}{2}

Step-by-step explanation:

first distribute

\frac{36x - 9}{2x}  = 15

next multiply both sides by 2x

36x - 9 = 15(2x) \\ 36x - 9 = 30x

simplify

- 9 =  - 6x

divide both sides by -6

\frac{ - 9}{ - 6}  = x \\   \frac{3}{2}  = x

two cyclists leave towns 74 miles apart at the same time and travel towards each other. one cyclist travels 3 mi/h faster than t
gizmo_the_mogwai [7]

The rates of each cyclist are 17mi/h and 20mi/h

What is rate?

Rate is a ratio that compares two different quantities which have different units.

In this comparison, one unit is taken to be a standard unit in which the other is compared with.

Analysis:

Let the speeds of both cyclists be x,  x+3

distance travelled by x cyclist = 2x

distance travelled by (x+3) cyclist = 2(x+3)

Total distance = 2x + 2(x+3) = 74 miles

2x +2x +6 = 74

4x + 6 = 74

4x = 74 - 6

4x = 68

x = 68/4 = 17mi/h

The other cyclist speed is x +3 = 17 +3 = 20mi/h
