Front

What is a literal equation?

Back

A literal equation is an equation that contains two or more variables. It is often solved for one variable in terms of the others.

Front

How do you isolate a variable in a literal equation?

Back

To isolate a variable, you perform inverse operations to both sides of the equation until the variable is alone on one side.

What is the formula for volume of a rectangular prism?

Back

The formula is V = lwh, where V is volume, l is length, w is width, and h is height.

Front

Solve for l in the equation V = lwh.

Back

l = \frac{V}{wh}.

Front

What does it mean to solve for a variable?

Back

To solve for a variable means to express that variable in terms of the other variables in the equation.

Front

What is the equation for a line in slope-intercept form?

Back

The equation is y = mx + b, where m is the slope and b is the y-intercept.

Front

Solve for m in the equation y = mx + b.

Back

m = \frac{y - b}{x}.

Front

What is the process to solve the equation dx + e = f for x?

Back

Rearrange the equation to isolate x: x = \frac{f - e}{d}.

Front

How do you solve for x in the equation xm = np?

Back

x = \frac{np}{m}.

Front

What is the formula for area of a rectangle?

Back

The formula is A = lw, where A is area, l is length, and w is width.
