Answer:
$19.50
Step-by-step explanation:
First, we find the number of gallons in 100 cups.
1 gallon = 16 cups
100 cups * (1 gallon)/(16 cups) = 6.25 gallons
100 cups is the same as 6.25 gallons.
Now we multiply the number of gallons by the cost per gallon.
6.25 gallons * 3.12 $/gallon = $19.50
Opinions because they are never wrong its just what you think not anyone else
Answer:
3x^2-4x+9 remainder -20/x+2
Step-by-step explanation:
Answer:
f(2) = 12
f(x) = 7, x = -3, 1
Step-by-step explanation:
<u>a)</u>
plug in x as 2
f(x) = 2^2 + 2(2) + 4
f(x) = 4 + 4 + 4
f(x) = 12
<u>b)</u>
replace f(x) with 7
7 = x^2 + 2x + 4
x^2 + 2x - 3 (move 7 to other side)
Factor
ac: -3x^2
b: 2x
split b into 3x, -x
(x^2 -x) + (3x - 3)
↓ ↓
x(x-1) + 3(x-1)
Factor: (x-1)(x+3) = 0
Solve using Zero Product Property:
x - 1 = 0, x + 3 = 0
x = 1, x = -3
