When Lakeesha solved the equation from problem 6-54, she reasoned this way: "Since groups of equals 3 groups of , then I know that each group of must equal ."

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

120 seems like the most sensible answer.

step-by-step explanation:

if there is only one topping on all caramel apples and there's 120 of them. then all apples should/will be covered in sprinkles. make sense?

thats not a system of equations, that is a solution
