Answer:
Let the no. Of cheese pizzas be x
Let the no. Of pepperoni pizzas be y
x + y = 45 (No. Of pizzas)
x = 45 - y
6x + 8.5y = 365 (cost of pizzas)
6(45-y) + 8.5y = 365
270 - 6y + 8.5y = 365
2.5y = 365 - 270
2.5y = 95
y = 95/2.5
y = 38
x = 7
Therefore 7 cheese pizzas were sold and 38 pepperoni pizzas were sold

The area of a triangle is half the product of the base and the height.
Since multiplication is commutative, the following expressions are equivalent:
So, option D is correct
Answer:
Below
Step-by-step explanation:
Let's say that each square on the grid represents 1 cm
First find the area of the two triangles
For the larger one: A = bh/2
A = 3 x 3 / 2
= 4.5 cm^2
For the smaller one : A = bh/2
A = 2 x 2 / 2
= 2 cm^2
For the rectangle : A = lw
A = 4 x 5
= 20 cm^2
Add them all up to get the area
4.5 + 2 + 20 = 26.5 cm^2
Hope this helps!
*Hint: When you have two y's, they could equal each other in order to solve for the x value.
|x^2 -3x + 1| = - (x - 1)
x^2 -3x + 1 = -x + 1
x^2 - 2x + 1 = 1
x^2 - 2x = 0
x (x - 2)
x = 2 and x = 0
Once both of them are plugged in, only x = 2 works so that's the value for x. Now we just plug it in order to solve for y.
y = x - 1
y = 2 - 1
y = 1
(2, 1)
The answer would be C.
