A.) Both services will cost the same if it is for a 3 hours service.
B.) 16+9X=20+7X.
=>9x-7x=20-16.
=>2x=4.
=>x=4/2.
=>x= 2.
Based on your question, the answer would be 168i
Y= 3x+12 all over 2.
Depending on what your x value is. The value of y will change. If x is 0, y is 6. If x is 1 y is 7.1
<u>Answer:</u>
7th Place
<u>Step-by-step explanation:</u>
Seeing as how the number of runners in front of Paula is
the number of runners behind her,
Assign the number of people behind Paula to a variable:
# of people behind Paula = b, which means
# of people ahead of Paula =
b
Use the variable to make an equation:
b (people behind Paula) +
b (people ahead of Paula) + 1 (Paula) = 25
b +
b + 1 = 25
Solve for b:
b +
b + 1 = 25
b +
b = 24
b = 24
b = 18
If there are 18 people behind Paula, there are
* 18 people in front of her, which is 6; This puts Paula in 7th place.
