To solve the equation x + 41 = 56, we need to isolate the variable x. To do this, we subtract 41 from both sides of the equation. This gives us x = 15. Therefore, the correct answer is X = 15.

The given equation is "a + 9 = 20". To find the value of 'a', we need to subtract 9 from both sides of the equation. This will give us "a = 20 - 9", which simplifies to "a = 11". Therefore, the correct answer is 11.

To solve for p, we need to evaluate the expression 888 + 99. Adding these two numbers gives us 987. Therefore, the value of p is 987.

To solve this expression, we can follow the order of operations (PEMDAS/BODMAS). First, we multiply 13 by -4, which gives us -52. Then, we subtract -3 from -52. Subtracting a negative number is the same as adding its positive counterpart, so -52 - (-3) becomes -52 + 3, which equals -49. Therefore, the correct answer is -49.

In the equation b - 6 = -9, we need to find the value of b. To isolate b, we can add 6 to both sides of the equation. This will give us b = -3. Therefore, the value of b is -3.

The expression 7 + (-5) x 3 can be solved using the order of operations, which states that multiplication should be done before addition. First, we multiply -5 by 3, which equals -15. Then, we add 7 to -15, resulting in -8. Therefore, the correct answer is -8.

The given inequality is x + 7

To solve this equation, we need to add 3 and -2. When we add a positive number and a negative number, we subtract the smaller number from the larger one and give the result the sign of the larger number. In this case, 3 is larger than 2, so we subtract 2 from 3, resulting in 1. Since the larger number is positive, the result is also positive. Therefore, the value of y is 1.

The dependent variable in this question is 5. This is because the value of X is determined by the value of a, and in this case, a is given as 5. Therefore, the value of X is 5 times 5, which equals 25.

The given question is asking for the value that, when divided by -8, gives a result of 40. To find this value, we can multiply 40 by -8, which equals -320. Therefore, the correct answer is -320.
