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

Answer:
63 sandwiches
Step-by-step explanation:
Pete and his friend Danny volunteered to bring sandwiches for lunch at a homeless shelter
They brought 7 loaves of bread
Each loaves have 18 slices
They used 2 slices each to make the sandwich
The first step is to calculate the total number of slices
Sinces 7 loaves of bread are used and each of them contain 18 slices then, the total number of slices can be calculated as follows
= 7 ×18
= 126 slices
Therefore since 2 slices of bread is used to make one sandwich then, the number of sandwiches that was made can be calculated as follows
= 126/2
= 63
Hence 63 sandwiches were made for the shelter
We are given to lines XY and VW. Now we need to determine the expression that correctly states that these lines are congruent. One possibility to prove that they're congruent is if they are two separate lines and:
XA is congruent to VB,
AY is congruent to BW
XA + AY = XY
VB + BW = VW
Then we can conclude that if the statements above are true, XY and VW must be congruent to each other.
Another possibility is that they are two sides of an isosceles rectangle XYVW and are opposite sides of the rectangle. <span />
