How many yards are equal to 252 inches?

Back

To convert inches to yards, divide by 36 (since 1 yard = 36 inches). 252 inches ÷ 36 = 7 yards.

What inequality represents 'Twice the difference of a number and 10 is less than 30'?

Back

The correct inequality is 2(x - 10) < 30.

Front

How do you calculate the slope of a line given two points?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1). For points (12, 16) and (8, 12), m = (12 - 16) / (8 - 12) = 1.

Front

What is the definition of a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed. It can be written in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of y with respect to x. It indicates how steep the line is.

Front

What is the formula for converting Celsius to Fahrenheit?

Back

The formula is F = (C × 9/5) + 32.

Front

What is the difference between an equation and an inequality?

Back
