Writing and Solving One Step Equations

5.  After dropping 5ºF, the temperature was 37ºF.  Which choice models this situation?

• d - 37 = 5
• d + 5 = 37
• d - 5 = 37
• d + 37 = 5

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

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

Which choice models this situation?

Last week, Tina worked 35 hours in 5 days. She worked the same number of hours each day. How many hours did she work each day?

• h - 5 = 35

• h + 5 = 35

• 5h = 35

• h/5 = 35

Sally bought three candy bars for a total of $18.00. How much did each candy bar cost? Write an equation to solve this problem. Use c as your variable.

• 18c=6
• c + 6= 18
• c +18 = 6
• 3c=18

Write an equation that models the following statement:

17 less than h equals 42

• 17-h=42

• h-17=42

• h+17=42

• 17+h=42

Which choice describes the step needed to isolate the variable? (Tap outside of the gray box to see the equation.)

• Divide both sides by 11
• Multiply both sides by 11.
• Add 11 to both sides.
• Subtract 11 to both sides.

Find the value of the variable: k - 2.14 = 85

• 82.86

• 2.99

• 87.14

Charlie has some candy. He shares ten pieces with Betsy and is left with 24 pieces. Which equation should I use to solve this problem?

• x +10 = 24

• x - 10 = 24

• 10x = 24

• x + 24 = 10

The _________ must be alone or isolated on one side of the equation.

• constant

• coefficient

• exponent

• variable

For which equation is x = 5 a solution?

• 2 + x = 3

• 3x = 15

• x - 7 = 12
