If you add 5x to 2x+2 you will get 7x+2. You would set this equation equal to 80, so it would be 7x+2=80. When you solve this you will get 11.1428571429, which can be rounded to 11, 11.1, or 11.14, whichever you prefer.
Step-by-step explanation:
put it in least to greatest and then put your fingers on the opposite side of the numbers and count down at the same time
Answer:
Flour
12/4 * 1 3/4 = 9/4 cups = 2 1/4 cups
Sugar
12/4 * 1 = 3 cups
Milk
12/4 * 1/3 = 1 cup
26/4=6.50
6.45=6.45
6and 2/5=6.40
50/8=6.25
so it should be
least- greatest
50/8, 6 & 2/5, 6.45, 26/4
Let x = cost of one cheese pizza.
Let y = cost of one pepperoni pizza.
Set up a system of equations.
6x + 7y = 153.50
2x + 2y = 47.00.
Multiply the second equation by -3
6x + 7y = 153.50
-6x - 6y = -141.00.
Add the equations together
y = $12.00.
Plug 12 into one of our original equations.
2x + 2(12) = 47.
Simplify the left side.
2x + 24 = 47.
Subtract 24 from each side.
2x = 23.
Divide each side by 2
x = $11.50
In conclusion, one pepperoni pizza costs $12.00
