10 gallons= 208
1 gallon: 208 ÷10= 20.8
(when you divide by 10, the decimal place jumps front 1 place!)
hope this helps!
When the X term is one, and doesn't have a leading coefficient, then you can factor it using the box and diamond method. look up videos on Khan Academy of the box and diamond method for solving trinomials. For number 9, you have a difference of squares. That means you can factor to just 2 terms. (x+4)(x-4) this works because 16 has an easy square root, and the sign in between is a negative(difference)
F(x)=-2x+8
This is because f(x) is the same as writing y so therefore you have to change the equation to 4x+2y=16 so you have Y=-2x+8

<u>12 cups oil </u>= <u> 1</u><u>8 cups oil</u><u> </u>
x 72 cups popcorn
Use cross multiplication and division to solve for x.
12 cups oil x 72 cups popcorn = 864
864/18 cups oil = 48 cups of popcorn
