1.
X + 325 = 369
Correct Answer
B. 44
Explanation
To find the value of X, we need to isolate it on one side of the equation. Subtracting 325 from both sides of the equation, we get X = 369 - 325. Simplifying this, we find X = 44. Therefore, the correct answer is 44.
2.
Y = 3x + 28 (x = 3) What is Y
Correct Answer
A. 37
Explanation
By substituting x = 3 into the equation Y = 3x + 28, we can find the value of Y. Plugging in x = 3, we get Y = 3(3) + 28, which simplifies to Y = 9 + 28. Combining like terms, Y = 37. Therefore, the value of Y is 37.
3.
X + 2x = 9 what is x
Correct Answer
B. 3
Explanation
The given equation is x + 2x = 9. To solve for x, we combine like terms on the left side of the equation, which gives us 3x = 9. To isolate x, we divide both sides of the equation by 3, resulting in x = 3. Therefore, the correct answer is 3.
4.
Y = 3x / 2 what is X
Correct Answer
D. 2y / 3
Explanation
The correct answer is 2y / 3 because to find the value of X, we need to isolate it on one side of the equation. We can do this by multiplying both sides of the equation by 2/3. This will cancel out the 3 in the numerator of the equation, leaving us with X = 2y / 3.
5.
What is 23x + 63 if x is 21
Correct Answer
B. 546
Explanation
The given question is asking for the value of 23 multiplied by x, which is 21, and then added to 63. So, we have 23 * 21 + 63. Evaluating this expression gives us 483 + 63, which equals 546.
6.
What is X in 9x + 3 = 21
Correct Answer
A. 2
Explanation
In the equation 9x + 3 = 21, the goal is to find the value of X. To isolate X, we need to move the constant term (3) to the other side of the equation. By subtracting 3 from both sides, we get 9x = 18. To solve for X, we divide both sides by 9, resulting in X = 2. Therefore, the correct answer is 2.
7.
What is x + x = 56 if (x is the same number)
Correct Answer
C. 28
Explanation
The equation is asking for the value of x when it is added to itself and equals 56. To find the answer, we need to determine what number when added to itself equals 56. The correct answer is 28 because 28 + 28 = 56.
8.
What is 2 * 2 * 6x if X = 21
Correct Answer
E. 504
Explanation
The given equation is 2 * 2 * 6x. To find the value of this expression when x = 21, we substitute x with 21. Therefore, the expression becomes 2 * 2 * 6 * 21. Simplifying this, we get 4 * 126, which equals 504.
9.
What is 3x / y if x = 56 and y = 2
Correct Answer
E. 84
Explanation
The given expression is 3x / y. Substituting x = 56 and y = 2 into the expression, we get 3 * 56 / 2 = 168 / 2 = 84. Therefore, the correct answer is 84.
10.
What is X and Y, if x + y = 96
Correct Answer
E. X = 46, Y = 50
Explanation
The correct answer is X = 46, Y = 50. This is because when you add 46 and 50 together, you get a sum of 96.
