Answer:

Assuming you wanted to find that mystery number:

It would be 5.75.

Step-by-step explanation:

5 = 4x - 18

Add 18 to both sides of the equation:

5 + 18 = 4x - 18 + 18

23 = 4x - 18 + 18

23 = 4x

Divide each side by 4:

(23/4) = (4x/4)

23/4 = x

5.75 = x

x = 5.75

I think the mathematical equation for this sentence is

<em>(Step 1)</em>

4x-18=5                    Add 18 to both sides to get the numbers on the same

 +18  | +18              Side of the equals sign.

----------------------      

4x =23

<em>(Step 2)</em>

4x =23  / 4           Divide equation by four

x=5.75                     The answer is X=5.75

Hope I was able to help :)

Answer all 3 for brainliest
fiasKO [112]

Answer:

7.) 53.38

8.) 18.84

9.) 87.92

Step-by-step explanation:

7.)

For the first question, we can see that the diameter is given. So, we will want to divide that diameter by 2 to get the radius. 17 ÷ 2 = 8.5.

The formula for finding the circumference is 2 × π × 8.5

2 × 3.14(π) = 6.28.

6.28 × 8.5 = 53.38

8.)

For the second question, we can see that the radius is now given to us which is 3ft.

The formula for finding the circumference is 2 × π × 3

2 × 3.14(π) = 6.28.

6.28 × 3 = 18.84

9.)

For the third question the raduis is also given to us, which is 14 in.

The formula for finding the circumference is 2 × π × 14.

2 × 3.14(π) = 6.28.

6.28 × 14 = 87.92
