Answer:
v = 66/7
Step-by-step explanation:
Step 1: Write equation
-7v + 3 = -63
Step 2: Solve for <em>v</em>
<u>Subtract 3 on both sides:</u> -7v = -66
<u>Divide both sides by -7:</u> v = 66/7
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
-7(66/7) + 3 = -63
-66 + 3 = -63
-63 = -63

Answer:
$37.5
Step-by-step explanation:
we can look at this problem using rates:
50=$25
25=$12.5
so we can add $12.5 to $25 because 50+25=75 so our answer, 12.5+25=37.5
$37.5
All you would need to to is do 13+23= 33 to get the total amount of people who dropped out, then do 72 ( the number in the beginning and subtract 33 from it because those are the people who dropped out so 72-33=39. 39 people finished the race.
