A, because $1.68 per mile is your rate, and since you don't know how many miles you will be going, you represent it with x. The initial fee of $2.15 is added to $1.68x so you can get your total cost. If you went 8 miles, your equation would be $1.68(8)+$2.15, however since there isnt a specific number of miles, we will use x.

The initial fee is the base, so that will not change.

Without knowing how many miles you're going you need x to substitute them, so the equation would be (using slope intercept form)

y= 1.68x + 2.15

A square has an area of 64 m². What is the length of each side?
anygoal [31]

Answer:

8m

Step-by-step explanation:

The area of a square is length*width.

We can square root the area to get the length of each side. Since the shape is a <em>square</em>, the lengths are the same.

\sqrt{64}=8

One side is <u>8m</u>.

The equation 3x + 2 = 29 is modeled below.
DanielleElmas [232]

Answer:

Subtract 2 from both sides.

Step-by-step explanation:

Remember to do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

> Also, note the equal sign, what you do to one side, you do to the other side of the equation.

First step is to subtract 2 from both sides of the equation:

3x + 2 (-2) = 29 (-2)

3x = 29 - 2

3x = 27

The second step is to divide 3 from both sides of the equation:

(3x)/3 = (27)/3

x = 27/3

x = 9
