Step-by-step explanation:
<u>Step 1: Define equation</u>
5x + 2 = 20
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 2 on both sides: 5x = 18
- Divide 5 on both sides: x = 18/5
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 5(18/5) + 2 = 20
- Multiply: 18 + 2 = 20
- Add: 20 = 20
Here we see that 20 does indeed equal 20.
∴ x = 18/5 is a solution to the equation.
A 2/5 of the students because because 8 out of the 20 students have speaking parts
Im pretty sure its D :) sorry if im wrong!!
F(w) = tw

Answer:
The answer is 15.24in.2
Step-by-step explanation:
I did the math and multiplied random numbers between 15 and 15.50 and eventually I got 239.425 by multiplying 15.24 with 3.14 and 2. The correct answer is actually 15.25 but on the test I guess they rounded it. Plz give brainliest.
