Explanation

To solve for X, subtract 8 from both sides of the equation:

3X + 8 - 8 = 20 - 8

3X = 12

Next, divide both sides by 3:

3X / 3 = 12 / 3

X = 4

So, the value of X is 4!

Explanation

The area of a circle is given by the formula:

A = πr^2

where A is the area and r is the radius.

Given the area is 98.56 cm^2, we can set up the equation:

98.56 = πr^2

Now, divide both sides by π (approximately 3.14):

r^2 = 98.56 / 3.14

r^2 = 31.36

r = √31.36

r ≈ 5.6

Now that we have the radius, we can find the circumference using the formula:

C = 2πr

C ≈ 2 × 3.14 × 5.6

C ≈ 35.2

So, the circumference is approximately 35.2 cm.

Explanation

Profit = Selling Price - Cost Price

= 60,000 - 57,000

= 3,000

To find the profit percentage, divide the profit by the cost price and multiply by 100:

Profit Percentage = (Profit ÷ Cost Price) × 100

= (3,000 ÷ 57,000) × 100

= 5.26%
