Answer:The inequality is
x greater than or equal to(>/=) 14
Step-by-step explanation:
Let x represent the possible cost of the full pizza. Tara eats 3 of the 10 slices and pays $4.20 for her share. This means that the amount of pizza that Tara ate is 3/10×x = 3x/10
Assuming that Tara has paid at least her fair share, therefore
3x/10 = 4.20
3x = 4.20 ×10 = 42
x = 42/3 = 14
This means that the total cost of the pizza is at least $14. The inequality
how much the pizza could have cost becomes
x greater than or equal to(>/=) 14
I don’t think you need to continue any further but there you go
Answer:
x = 2 y= 1
Step-by-step explanation:
Solve the system by elimination by stacking the equations lining up the variables.
x + 3y = 5
-x - y = -3
Next, add each of the like terms.
x + 3y = 5
+ -x - y = -3
-----------------------
0x + 2y = 2
y = 1
Then substitute y = 1 into one of the equations.
x + 3(1) = 5
x + 3 = 5
x = 2
A) to work out area of a circular pan you use 3.14 x R^2 so the area would be 3.14x(6)^2, which gives us 113.04in^2. The rectangular pan has area 8x11 which is 88in^2.
B) to work out volume you multiple the areas by the depth. So the circular one is 226.09in^3 and the rectangular one is 176in^3.
C) this means that the circular pan has a larger volume
Hope this helped and sorry if anything is wrong :)
