Which of the following equations can be use to find the one "TRUE" solution for  $2\left|2x+12\right|=14x-6$  ?

• 2x+12 = 7x-3

Major League Soccer (MLS) rules state that soccer balls are to be inflated to an average of 12.5 PSI (Pounds per Square Inch). Prior to each game, the referees check the three game balls. If the game balls are inflated to 1 PSI more or less of the desired weight, they are approved for use in the game. Which absolute value equation best represents the least and the most that a MLS soccer ball weighs?

• |x-1| = 12.5

• |x-12.5| = 1

• |x+1| = 12.5

• |x+12.5| = 1

At the Longhorn Video Game Design company, the average starting salary for a new designer is $42, 500. The actual salary could differ by $3,200. Which absolute value equation is used to determine the highest and the lowest salary for a new designer at Longhorn Video Game Design?

• |x-3,200| = 42, 500

• |x+3,200| = 42, 500

• |x-42,500| = 3,200

• |x+42,500| = 3,200

You have money in your wallet but you don't know the exact amount. When a friend asks you, you say that you have 50 dollars give or take 15. Write an absolute value equation to model this situation.

• |x-50| = 15

• |x+15| = 50

• |50+x| = 15

• None

The U.S. Mint produces quarters that weigh about 5.67 grams each. After the quarters are produced, a machine weighs them. If the quarter varies by 0.04 gram than the desired weight, the quarter is rejected. Write an absolute value equation to model this situation.

• |x-5.67| = 0.04

• |x-5.67| = -0.04

• |x+5.67| = 0.04

• None

• -6 < x < -2

• x< -6 or x > -2

• x < 2 or x > 6
