Question

1. which expression has a value of -15? 6.3d show work for each choice a. -2(5) - (-5) c. (20 ÷ -2) - 5 b. -3 + 4(4) d. (-10 ÷ -5) - (-13)

Explanation:

Step1: Evaluate Option A

First multiply, then simplify subtraction:

$$\begin{align*} -2(5) - (-5) &= -10 + 5 \\ &= -5 \end{align*}$$

Step2: Evaluate Option B

First multiply, then add:

$$\begin{align*} -3 + 4(4) &= -3 + 16 \\ &= 13 \end{align*}$$

Step3: Evaluate Option C

First divide, then subtract:

$$\begin{align*} (20 \div -2) - 5 &= -10 - 5 \\ &= -15 \end{align*}$$

Step4: Evaluate Option D

First divide, then simplify subtraction:

$$\begin{align*} (-10 \div -5) - (-13) &= 2 + 13 \\ &= 15 \end{align*}$$

Answer:

C. $(20 \div -2) - 5$
