Calculate (20) / (-4) + (-2) x (-10) - (-2) x (7):

Calculate (20) / (-4) + (-2) x (-10) - (-2) x (7):

• A. 19
• B. -29
• C. 29
• D. 9

Answer: (C)

To evaluate the expression step-by-step: First, handle the division and multiplication as they take precedence over addition and subtraction. Begin with the division: (20) / (-4) = -5 Next, perform the multiplications: (-2) x (-10) = 20 (-2) x (7) = -14 Now, substitute these results back into the expression: -5 + 20 - (-14) The expression simplifies to: -5 + 20 + 14 Next, perform the addition: -5 + 20 = 15 15 + 14 = 29 Thus, the entire expression evaluates to 29. This thorough breakdown showcases how each operation is executed according to the order of operations, confirming that the answer of 29 is indeed correct.

To evaluate the expression step-by-step:

First, handle the division and multiplication as they take precedence over addition and subtraction. Begin with the division:

(20) / (-4) = -5

Next, perform the multiplications:

(-2) x (-10) = 20

(-2) x (7) = -14

Now, substitute these results back into the expression:

-5 + 20 - (-14)

The expression simplifies to:

-5 + 20 + 14

Next, perform the addition:

-5 + 20 = 15

15 + 14 = 29

Thus, the entire expression evaluates to 29. This thorough breakdown showcases how each operation is executed according to the order of operations, confirming that the answer of 29 is indeed correct.
