Set up the system of equations:


We'll use elimination to solve this system of equations.
Take the coefficients for y in both problems. Multiply one of them by -1:

Since this coefficient is taken from the first problem, we'll multiply the entire second problem by this negative coefficient:

Take the coefficient for y in the second problem and multiply the entire first problem by that coefficient:

Your system should now look like this:


Combine these two equations to cancel out y:

Divide both sides by 5 to get x by itself:
A fairy soda costs $1.50.Because we know the value of one of the variables, we can plug it into one of the equations:


Subtract 12 from both sides:

Divide both sides by 5 to get y by itself:
A fairy hotdog costs $3.75.
Answer:
$125
Step-by-step explanation:
Since there are 12 months in a year, divide the total bill by the total number of months.
1500/12 = $125
Multiply both sides by 4
subtract 24r from both sides
simplify r - 24r to -23r
divide both sides by -23
two negatives make a positive
simplify 14/5/23 to 14/5 x 23
simplify 5 x 23 to 115
switch sides
Answer: r = 14/115.

Answer:
The height of the pan is 2 inches.
Step-by-step explanation:
Given : Paul bags of raisin bars in a pan shaped like a rectangle or prism the volume of the pan is 252 in.³ the length of the pants 12 inches and it's with is
inches.
To find : What is the height of the pan ?
Solution :
The volume of a rectangle or prism is

Where, l=12 inches is the length
inches is the width
V=252 in.³ is the volume
h is the height
Substitute the value,




Therefore, the height of the pan is 2 inches.
