Answer:
75 minutes
Step-by-step explanation:
Make an equation
4 pies to 15 minutes = 20 pies to x minutes
4 / 15 = 20 / x
Now cross multiply
4x = 15 × 20
And multiply 15 and 20
4x = 300
Then divide both sides by 4
x = 75
So your answer is 75 minutes
Answer:
6.4
Step-by-step explanation:
Well the radius of the whole pizza is 8
So the total area is 64π
And 64 / 10 = 6.4
Only the first one works
y = 3(-1)-2 = -5
y = -(0) -6 = -6 not -2
This is a substitution problem...
