Summer Solving Inequalities and Equations

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides
• Subtract 11 from both sides
• Add 11 to both sides
• Divide 3 on both sides.

Figure out what n equals in this equation:
6n + 4 = -26

• n=-6
• n= -5
• n= 8
• n= -4

-8x = -96

• x = -12
• x = 12
• x = 13
• x = 14

Solve: -7(z - 6) = -70

• 16
• -16
• 8
• -1/2

Solve: 3(x-4) = -3

• 3
• -3
• 5
• -5

Your cell phone bill is $21.20.  The company charges $0.25 per call. Let c = number of calls.  Write an equation to find how many calls you made.

• 0.25c = 21.20
• c - 0.25 = 21.20
• c + 0.25 = 21.20
• 0.25 ÷ c = 21.20

Rachel and Sharon are splitting up their Pokemon cards.  Rachel has 4 fewer than 3 times as many as Sharon.  Together they have 100 cards.  Which equation could be used to solve for how many cards Sharon had originally?

• n + (3n - 4) = 100
• n - (3n - 4) = 100
• n + (4 - 3n) = 100
• 4 - 3n = 100

A limo driver needs to make more than $450 in one day.  He charges a rental fee of $375 and $0.85 per mile.  What inequality represents the number of miles, x, he would have to drive to reach his goal?

• 0.85x + 375 > 450
• 0.85x + 375 < 450
• 0.85 + 375x > 450
• 0.85 + 375x < 450
