Question

Which of the following expressions has a value of 3? Select all that apply. -6 ÷ -2 4 - (-1) (-1)(-3) (-2) - 1 15 ÷ -5 4 + 1

Answer 1

The expressions -6 ÷ -2, (-1)(-3), and 4 + 1 all have a value of 3.

Step-by-step explanation:

The expressions -6 ÷ -2, (-1)(-3), and 4 + 1 all have a value of 3.

To calculate the value of -6 ÷ -2, we divide -6 by -2. A negative divided by a negative is positive, so -6 ÷ -2 = 3.

To calculate the value of (-1)(-3), we multiply -1 and -3. Two negatives multiplied together result in a positive, so (-1)(-3) = 3.

To calculate the value of 4 + 1, we add 4 and 1. 4 + 1 equals 5, not 3.

Answer 2

-6 ÷ -2 and (-1)(-3)

Step-by-step explanation:

we need to find the expression that gives the value of 3

-6 ÷ -2 ,
`(-6)/(-2) =3` is 3 because negative and negative is positive

4 - (-1),
`4 - (-1)=4+1=5` which is not equal to 3

(-1)(-3),
`(-1)(-3)=3` negative times negative is positive

(-2) - 1,
`(-2) - 1=-3` which is not equal to 3

15 ÷ -5 ,
`(15)/(-5) =-3`, not equal to 3

4 + 1,
`4+1= 5`

-6 ÷ -2 and (-1)(-3) gives us the value of 3
