Answers

Answer:

2. 19.47 in

3. 153.86 square centimeters

Step-by-step explanation:

2. The circumference of a circle is π times the diameter, so in this case it is 6.2 * 3.14 = 19.47 in (rounding to nearest hunderdth).

3. The area of a circle is π/4 times the diameter squared, so in this case it is 14^2 * 3.14 / 4 = 153.86 square centimeters.

solve for x in the following question 2x - 3 = 1

Answers

Answer:

x = 2

Step-by-step explanation:

2x-3 = 1

use addition property of equality (add 3 to each side to keep balance)

2x = 4

use division property of equality (divide both sides by 2)

4/2 = 2

so,

x = 2

Please mark me brainliest, and I really hope you have a great day!

Solve for X: 2x - 3 = 1
2x - 3 + 3 = 1 + 3
2x = 4
2x/2 = 4/2
X = 2

So, in conclusion, X is equal to 2.
