What is 1/4(x+16)-x equal too
schepotkina [342]
<span>1/4(x + 16) - x =

First, distribute the 1/4.

= 1/4x + 1/4 * 16 - x

= 1/4x + 4 - x

= 1/4x + 4 - 4/4x

= 1/4x - 4/4x + 4

= -3/4x + 4

= -\dfrac{3}{4}x + 4</span>

Help and explanation.
Natasha_Volkova [10]

Answer:

Andrew

Step-by-step explanation:

Abby:

Since red cards are negative, a red 9 would represent the number -9. And because black cards are positive, a black 6 would represent the number 6. To get the sum, we add the two numbers together:

-9 + 6

That gives us a total of -3.

Ashley:

We can do the same thing as before. A black seven would represent 7 and a red 8 would represent -8. Next we again add them together:

7 + (-8)

That gives us a total of -1.

Andrew:

The red 4 is -4, while the black 4 is 4:

-4 + 4

That gives us a total of 0.

Anna:

Anna has a red 8 which represents -8 and another red, a three, which would represent -3. We can add the two to get:

-8 + (-3)

That gives us a total of -11.

In all, Andrew has the highest sum of 0, which means he won the game.
