If popcorn is p and water is w the equation can be written as
3p + w = 9.25
because there was 3 boxes of popcorn and one water (hence the coefficients) and the total is 9.25
then plug in 1.75 for w the price of water:
3p+ 1.75 = 9.25
you can move stuff around algebraically now (subtract 1.75 on both sides and divide by three on both aides) to get the cost of one box of popcorn (p).
The answer is 2.50
Answer:
jack (with the lower case j) is 11 years old
Step-by-step explanation:
(x - 5) + (3x - 5) = 34
x - 5 + 3x - 5 = 34
4x = 34 + 10
4x = 44
x = 11
So, jack = 11 years old.
Jack = 33 years old.

Explanation:
_________________________________________________________
Let "x" represent the numerical value of [the man's age].
500 - 3x = 200 ; Solve for "x" ;
Subtract "500" from each side of the equation:
500 - 3x - 500 = 200 - 500 ;
to get:
- 3x = -300 ;
Now, divide each side of the equation by "-3" ; to isolate "x" on one side of the equation; & to solve for "x" ;
- 3x / -3 = -300 / -3 ;
x = 100 .

The answer is: " 100 " .

<span>|3x| = 12 actually represents two equations: 3x = 12 and -3x = 12.
Thus, the solutions are {-4, 4).</span>
