Answer:

  k = -1

Step-by-step explanation:

Subtract 10 and simplify. We choose this value so the constants on the right add up to give 0.

  3 -10 = 3 + 7k + 7 -10

 -7 = 7k

Divide by 7.

  -7/7 = 7k/7

  -1 = k

Anne picked out 3 board games from her cabinet to take to a game night with her friends. She still has more than 10 board games
Tresset [83]

Answer:

x - 3 > 10

There were more than

13

board games in Anne's cabinet to start.

Step-by-step explanation:

The variable x represents how many board games were in Anne's cabinet to start. Since she has already picked out 3 board games to bring, the expression x–3 represents how many board games are still in the cabinet.

And, since Anne has more than 10 board games still in her cabinet, x–3 must be greater than 10.

This inequality shows the relationship.

x–3>10

Now, solve for x.

x–3

> 10

x–3+3

> 10+3 Add 3 to both sides

x

> 13 Simplify

So, there were more than 13 board games in Anne's cabinet to start.
