Answer:
120 slices
Step-by-step explanation:
We are given that each slice is 1 over 10 of a pizza, so there are 10 slices per pizza (because the denominator represents the total amount of pieces). Since there are 12 pizzas, 12 x 10 = a total of 120 slices.
Answer:
1
Step-by-step explanation:
We can find the slope by using
m= (y2-y1)/(x2-x1)
= (6-1)/(6-1)
= 5/5
= 1
You can solve this by substitution.
x+y=10
x-y=4
===== add the equations
2x=14
x=7
Then plug in x into one of the equations
7+y=10
y=3
so x^2=7*7=49
y^2=3*3=9
Hope that helps!

try to combine fractions in numerator and denomenator
numerator: 
make common denom
multiply left one by

denomenator
make common denom
multiply left one by
