A number plus half of the number, minus 20 is the same as one-fourth of the original number. What is the number?

16

Step-by-step explanation:

Let the number = x

x + x/2 - 20 = 1/4 x

3/2 x - 20 = 1/4x             Multiply by 4

3*2 x - 80 = x

6x - 80 = x

6x - x - 80 = 0

5x - 80 = 0

5x = 80

x = 16

Check

16 + 8 - 20 = 1/4 * 16

24 - 20 = 4

4 = 4

it should be a and d. lmk if i'm wrong xd

exa:

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
