For this case, the first thing we must do is define variables.
We have then:
x: cost of each bag of popcorn
y: cost of each drink
writing the system of equations we have:
9x + 9y = 117
x + 3y = 23
Solving the system of equations we have:
x = 8 $
y = 5 $
Answer:
a system of equations that can be used to find the price of one bag of popcorn and the price of one drink is:
9x + 9y = 117
x + 3y = 23
The price of a bag of popcorn is $ 8.
Answer:
14.5
Step-by-step explanation:
6 (1/4 + 5/2) - 2
6 (.25 + 2.5) - 2
(1.5 + 15) - 2
16.5 - 2
14.5
Answer:
false
Step-by-step explanation:
Answer:
v = -6
Step-by-step explanation:
1. Add the opposite (turn each subtraction sign into an addition sign and change the number in front of the addition sign to a negative or positive depending on what it was originally).
2. Subtract 4v from both sides of the equation.
3. Subtract 36 from both sides of the equation.
4. Divide both sides of the equation by 9.
5. You will be left with v = -6.
Zero
There is no solution for these equations as there is no even one point of intersection between them
