<span>Let Rico's speed be S
Then Luis' is: 3S
</span>We then get: seventy-two over s equals seventy-two over three s plus four 
216=72+12s  Multiplying by LCD, 3S
216-72=12s
<span>144 = 12S
</span><span>S, or Rico's speed would be 144 over 12 or 12mph</span>

Solve for each of the following proportions:<br> a. 5/x=30/42<br> b. x/8=-12/32
andreev551 [17]

Answer:

A. x = 7

B. x = -3

Step-by-step explanation:

A.  5/x = 30/42

5/x = 5/7

5 = 5/7 x

5= 5x/7

5 x 7 = 5x

35 = 5x

35/5 = x

7 = x

x = 7

B.  x/8 = -12/32

x/8 = -3/8

x = - 3/8 x 8

x = -  24/8

x = -3

Hope this helps you have a gr8 day :3
