What is the solution to the inequality x - 14 < -8?

Back

x < 6

Front

If a number is missing in an equation and the answer is 2, what could the equation be?

Back

x = 2

Front

In similar figures, if one side is x and the corresponding side is 5, what is the value of x if the ratio is maintained?

Back

x = 5

Front

How do you set up an equation to find the hours of labor if the total bill is $458, with $98 for parts and $45 per hour for labor?

Back

98 + 45x = 458

Front

What does it mean for two figures to be similar?

What is the formula for finding the total cost when parts and labor are involved?

Back

Total Cost = Cost of Parts + (Hourly Rate × Number of Hours)

Front

What does it mean to find a missing value in an equation?

Back

Finding a missing value means solving for a variable in an equation to determine its value.

Front

What is the relationship between similar figures?

Back

The corresponding angles of similar figures are equal, and the lengths of corresponding sides are proportional.

Front

How do you solve the equation 98 + 45x = 458 for x?

Back

Subtract 98 from both sides to get 45x = 360, then divide by 45 to find x = 8.
