Step-by-step explanation:
<u>Step 1: Define Equation</u>
4x - 8 = 16
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 8 to both sides: 4x = 24
- Divide 4 on both sides: x = 6
<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>: 4(6) - 8 = 16
- Multiply: 24 - 8 = 16
- Subtract: 16 = 16
Here we see that 16 does indeed equal 16.
∴ x = 6 is the solution to the equation.
There are 20 groups of fish
2)) answer is 73
4)) answer is 5(x + 2)
The experimental probability is how many times it landed on heads over the amount of times it was flipped.
The coin landed on heads 32 times out of 50 flips which is 32/50 which equals 0.64, which is 64%
The answer is D.
