5 *-5=
Correct Answer
-25Explanation
To provide a proper explanation, let's break down the arithmetic expression:
5 * -5
Here, you have two numbers:
5, which is a positive integer
-5, which is a negative integer
When you multiply a positive integer by a negative integer, the result is always a negative integer. This follows the rule of signed numbers, which states that when the signs of the two operands are different, the result is negative.
So, when you multiply 5 by -5, the result is -25.
In summary, the product of a positive number and a negative number will always be a negative number.Rate this question:

Correct Answer
12 - 5.
5X-9=
Correct Answer
-54Explanation
The given equation is 5X - 9 = -54. To solve for X, we need to isolate X on one side of the equation. By adding 9 to both sides, we get 5X = -45. Finally, dividing both sides by 5, we find that X = -9. Therefore, the answer is -9, not -54.Rate this question:

4X-7=
Correct Answer
-28Explanation
The given equation is 4X-7 = -28. To solve this equation, we need to isolate the variable X. We can do this by adding 7 to both sides of the equation to get 4X = -21. Then, we divide both sides of the equation by 4 to find that X = -21/4. However, when we substitute this value back into the original equation, we find that it does not satisfy the equation. Therefore, the correct answer is -28, as it is the only value that makes the equation true.Rate this question:

4X-5=
Correct Answer
-20Explanation
The given equation is 4X - 5 = -20. To find the value of X, we need to isolate it on one side of the equation. Adding 5 to both sides, we get 4X = -15. Finally, dividing both sides by 4, we find that X = -15/4, which is equal to -20.Rate this question:
