Karen makes $5 per hour babysitting and $12 per hour giving music lessons. One weekend, she worked a total of 18 hours and made $139. How many hours did she spend babysitting?

• 4 hours

• 7 hours

• 11 hours

• 18 hours

When graphing the below inequality, which type of line would you use?

• solid

• dotted

• shaded

• unshaded

What inequality does the number line graph represent?

• -x + 3 ≥ 1

• -5x + 3 > -7

• x + 1 < 3

• 5x + 3 ≥ 13

What is the next step to solve this equation? 3x - 5 = 7

• Add 5 to both sides of the equation

• Add 3x to both sides of the equation

• Subtract 5 from both sides of the equation

• Subtract 7 from both sides of the equation

Does the sign need to flip when solving? -4y ≥ 28

• YES

• NO

20 ≥ x + 13

• x ≤ 7

• x ≥ 7

• x ≤ 33

• x ≥ 33

What inequality does the number line graph represent?

• x ≤ 4

• x ≥ -4

• x < -4

• x < 4
