Let's solve each question step by step.
Question 1: X - 23 = 56 To find X, we can add 23 to both sides of the equation:
X - 23 + 23 = 56 + 23
X = 79
Correct Response: 79
Question 2: 15 + x = 31 To find x, we can subtract 15 from both sides of the equation:
15 + x - 15 = 31 - 15
x = 16
Correct Response: 16
Question 3: 2x = 56 To find x, we can divide both sides by 2:
2x / 2 = 56 / 2
x = 28
Correct Response: 28
Question 4: What do you do to solve this equation for A? x^2 = 30 To solve for x, we take the square root of both sides.
This option isn’t presented, but we know that taking the square root is the correct operation. However, it doesn’t appear we have a response option to select.
If we assume the original question might have provided options, the process would typically involve taking the square root: x = ±√30.
Correct Response: (This question seems to be missing the correct responses relevant to square roots.)
Question 5: Solve for X x^3 = 12 To find x, we take the cube root of both sides:
x = 12^(1/3) ≈ 2.29.
However, rounding would give us about 2. However, the option choices do not include this.
If we were to try and find an option that could match closely, we see the only somewhat related number to cube calculations would be x = 9, but that isn't accurate.
If you were looking for a numerical estimate based on close whole numbers, the cube root of 12 lies between 2 and 3, likely indicating options may have notation issues.
Correct Response: None of the given options accurately correspond to x^3 = 12.
