Answer:

The circumference is 14 and the area of this circle would be close to 153.94.

Step-by-step explanation:

The circumference of a circle is the measure of it from one side to another. In this case it is 14.

The radius on the other hand is half of the circumference and only extends from the middle of the circle out. Half of 14 is 7.

In order to find the area, you will need the formula.

A = $\pi r^2$

Plug in the numbers:

A = $\pi$ ( $7^2$ )

You solve and get approximately 153.94

Solve for x. -0.65 + 0.45x = 5.4

Answer:

x = 13.444 ... (repeating decimal) or;

x = 13 4/9

Step-by-step explanation:

-0.65 + 0.45x = 5.4

First we will add 0.65 to each 'side' of the equation.

0.65 + (-0.65) + 0.45x = 0.65 + 5.4

0.65 + (-0.65) = 0

0.65 + 5.4 = 6.05

Input the numbers, and now the equation looks like this:

0 + 0.45x = 6.05

Remove the zero:

0.45x = 6.05

Divide each 'side' by 0.45.

0.45x ÷ 0.45 = 6.05 ÷ 0.45

0.45x ÷ 0.45 = 1x = x

6.05 ÷ 0.45 = 13.444 ... repeating decimal

Input the numbers, and now the equation looks like this:

x = 13.444 ... repeating decimal

We can also write this as:

x = 13 4/9 in fraction form
