Question

An equation is shown below:

−2(4x − 1) − 7 = 5

Which statement shows a correct next step in solving the equation?

A)The equation can become −2(4x − 1) = −2 by applying the distributive property.
B)The equation can become −2(4x − 1) = 12 by applying the addition property of equality.
C)The equation can become −2(4x − 1) = 12 by applying the commutative property of addition
D)The equation can become −2(4x − 1) = −2 by applying the subtraction property of equality.

Answer 1

Try the easiest step in isolating x and simplifying the equation. By adding 7 to both sides of the equation, it gets rid of -7 on the left side of the equation. What property is that called?

Answer 2

distributive?

Answer 8

Sarah decides to take her six year old son to the circus. The price for the child's ticket is 4.75 dollars less than the price for the adult's ticket. If you represent the price for the child's ticket using the variable "x," how would you write the algebraic expression for the adult's ticket price?

4.75x
x + 4.75
x over 4.75
x4.75

Answer 9

Let's say that the adult's circus ticket is the variable y. The child's circus ticket is represented by x. But the adult's ticket costs $4.75 more. What do you need to do with the child's ticket to receive the price of the adult's?
