Answer:
A plain pizza is $10.50 and a pepperoni pizza is $12.50
Step-by-step explanation:
Create a system of equations where x is the price of a pepperoni pizza and y is the price of a plain pizza:
3x + 2y = 58.5
2x + 4y = 67
Solve by elimination by multiplying the top equation by -2:
-6x - 4y = -117
2x + 4y = 67
Add these together and solve for x:
-4x = -50
x = 12.5
So, a pepperoni pizza is $12.50. Plug in 12.5 as x into one of the equations, and solve for y:
2x + 4y = 67
2(12.5) + 4y = 67
25 + 4y = 67
4y = 42
y = 10.5
So, a plain pizza is $10.50.
A plain pizza is $10.50 and a pepperoni pizza is $12.50

Answer:
220 meter
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Area of square = 275 square meters
Side length (a) = 55 meters
We can calculate the perimeter of square by using following formula,
Perimeter of square = 4a
By putting the value, we get
Perimeter of square = 4 × 55 mt
= 220 meter
Hence, the perimeter of the square is 220 meter.
The surface area would be 17.6ft2
Explanation:
2 x 1 x 1/2 = 1
2 x 1 x 1/2 = 1
3 x 1 = 3
3 x 2 = 6
3 x 2.2 = 6.6
6.6 + 6 + 3 + 1 + 1 = 17.6
