Answer:
HAPPY BURFDAY
Step-by-step explanation:
Equation 1 for tickets sold:
$35x + $25y = $10,250
Equation 2 for quantity (number #) of tickets sold:
x + y = 350
Use substitution method:
y = 350 - x
35x + 25 (350 - x) = $10,250
35x + $8750 - 25x = $10,250
10x + $8750 = $10,250
- $8,750 -$8,750
10x = 1,500
x = 150
y = 350 - 150
y = 200
Check the answers:
$35 (150) + $25 (200) =
$5,250 + $5,000 = $10,250
First we can either add 19 and 11, or we can do this another way.
19 + 11 = 30 To find how much thirty tens are, just add a 0 on the end of 30: 300
The other longer way to do it is: add a 0 to 19: 190, then add a 0 to 11: 110
110 + 190 = 300
There is your answer!

Answer:
Steve should order the round pizza to get more crust.
Step-by-step explanation:
They are essentially asking which pizza has a larger perimeter, because we can assume that the crust is of equal thickness on either pizza. To find the side length of the square pizza we find the square root of the area, 
=7 and to get the perimeter from the side length we multiply by 4, 
. To get the perimeter of the round pizza we first find the radius from the area. The formula for area of a circle is π*r^2 so we divide the area by π to get 49, and the square root of 49 gives us a radius of 7. To get perimeter of a circle, also called circumference, you multiply the diameter times π and the diameter is twice the radius. We multiply 7 by 2 to get the diameter, 14 and then multiply by pi to get the circumference which is approximately 43.982. 43.982 is larger than 28 so Steve should order the round pizza.
