question 12
solve for x
3x + 5 = 20
○ x = 4
○ x = 5
○ x = 6.33
○ x = 8.33
question 13
if the diameter of a circle is 20, what is the area of the circle?

Explanation:

Step1: Subtract 5 from both sides

Given the equation \(3x + 5 = 20\), we subtract 5 from both sides to isolate the term with \(x\). So, \(3x + 5 - 5 = 20 - 5\), which simplifies to \(3x = 15\).

Step2: Divide by 3

Now, we divide both sides of the equation \(3x = 15\) by 3 to solve for \(x\). That is, \(\frac{3x}{3}=\frac{15}{3}\), which gives \(x = 5\).

Answer:

B. \(x = 5\)
