### Solve for x in this equation: x + 41 = 56

• A.

X = 10

• B.

X = 12

• C.

X = 15

• D.

X = 20

C. X = 15
Explanation
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.

### 3 + (-2) = y.   What is the value for y?

• A.

1

• B.

-1

• C.

2

• D.

-2

A. 1
Explanation
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.

### 7 + (-5) x 3 = ..

• A.

22

• B.

6

• C.

36

• D.

-8

D. -8
Explanation
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.

### 13 x (-4) - (-3) = ...

• A.

-52

• B.

61

• C.

-49

• D.

49

C. -49
Explanation
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.

• 5.

### 40 : (-8) = ...

• A.

320

• B.

-5

• C.

8

• D.

5

C. 8
Explanation
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.

Rate this question:

• 6.

### Solve for p. p=888+99

• A.

90

• B.

11

• C.

987

• D.

900

C. 987
Explanation
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.

• A.

X<1

• B.

• C.

X>1

• D.

X>2

A. X<1
Explanation
The given inequality is x + 7 < 8. To solve this inequality, we subtract 7 from both sides of the inequality to isolate the variable x. This gives us x < 1, which means that the value of x is less than 1.

• 8.

### What's the dependent variable? X=5a

• A.

X

• B.

A

• C.

5

• D.

Not given

C. 5
Explanation
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.

Rate this question:

• 9.

### A + 9 = 20

• A.

9

• B.

10

• C.

20

• D.

11

D. 11
Explanation
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.

Rate this question:

• 10.

### What is the value of 'b' in the equation? b - 6 = -9

• A.

2

• B.

-3

• C.

3

• D.

-15

B. -3
Explanation
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.
