- D.
261
Correct Answer
A. -225Explanation
The given question requires adding 243 and 18. When adding a positive number to a negative number, we subtract the smaller absolute value from the larger absolute value and keep the sign of the number with the larger absolute value. In this case, the absolute value of -243 is larger than 18, so we subtract 18 from 243 and keep the negative sign, resulting in -225.Rate this question:

-188
- D.
188
Correct Answer
D. 188Explanation
When adding a positive number and a negative number, the result will have the sign of the larger number. In this case, 196 is positive and -8 is negative. Since 196 is larger in magnitude, the result will be positive. Therefore, the correct answer is 188.Rate this question:

- D.
-3
Correct Answer
D. -3Explanation
When x = 1 and y = 2, we can substitute these values into the expression x - 2y + 2x - y. Simplifying the expression, we get 1 - 4 + 2 - 2 = -3. Therefore, the correct answer is -3.Rate this question:

(-13t + 8z) + (-24t - 9z)
- A.
-37t + z
- B.
-37t - z
- C.
-14t -z
- D.
-14t + z
Correct Answer
B. -37t - zExplanation
The given expression is (-13t + 8z) + (-24t - 9z). To simplify this expression, we can combine like terms. The t terms are -13t and -24t, which can be combined to give -37t. Similarly, the z terms are 8z and -9z, which can be combined to give -z. Therefore, the simplified expression is -37t - z.Rate this question:
