Paige used 1 1/2 cups of flour and 1/4 of butter to make 12 muffins. How much flour and butter would Paige need for 18 muffins?
maks197457 [2]

Answer:

3/4 cup

Step-by-step explanation:

12 divided by 2 is 6

18 - 12 = 6

we are going to need half of 1 1/2 cup of flour

1 cup = 1/2

1/2 cup = 1/4

1/2 and 1/4 cup = 3/4 cup

If f(x)= 5x + 40, what is f(x) when x = -5?
kap26 [50]

Answer:

f(x) = 15

Step-by-step explanation:

"If f(x)= 5x + 40, what is f(x) when x = -5?"

Substitute x for -5:

f(x) = 5x + 40

f(x) = 5(-5) + 40

f(x) = -25 + 40

f(x) = 15
