Answer:
4
Step-by-step explanation:
We can find the greatest common factor by listing the factors of both numbers.
Factors of 12 : 1, 2, 3, 4, 6, 12
Factors of 20 : 1, 2, 4, 5, 10, 20
The common factors are : 1, 2, 4
The greatest common factor is 4

Answer:
y = 5
Step-by-step explanation:
3y - 2 = 13
We are solving for y, so we want to isolate it.
Add 2 to both sides.
3y = 15
Continue isolating y by dividing both sides by 3.
y = 5
Check your answer by plugging it back into the original equation.
3y - 2 = 13
3(5) - 2 = 13
Multiply.
15 - 2 = 13
Subtract.
13 = 13
Your answer is correct.

A) 3 centerpieces per hour because 15/5 = 3
b) 14 hours, because 3 goes into 42 14 times exactly.
