WEEK 2 Sessions 2 Literal Equations Quiz

What is a literal equation?

• An equation with only one variable

• An equation with more than one variable

• An equation with no variables

• An equation with only constants

What is the first step in solving a literal equation?

• Add variables to both sides

• Simplify each side by combining like terms

• Multiply both sides by zero

• Subtract constants from both sides

Which operation is used to isolate the indicated variable in a literal equation?

• Only addition

• Only subtraction

• Inverse operations

• Only multiplication

In the example given, what is the final expression for x in the equation 3x + 4y = 7?

• x = (7 + 4y) / 3

• x = (7 - 4y) / 3

• x = (7 - 4y) * 3

• x = 7 - 4y

In the example given, what is the final expression for F in the equation C = 5/9(F - 32)?

• F = 9/5C - 32

• F = 5/9C + 32

• F = 9/5C + 32

• F = 5/9C - 32

Boyle's Law involves the pressure and volume of gas in a container. It can be represented by the formula $ P_1V_1 = P_2V_2 $. When the formula is solved for $ P_2 $, the result is

• $ P_1V_1V_2 $

• $ p_1 = Fr + p_2 $

• $ p_2 = p_1 - Fr $

• $ r = F(p_2 - p_1) $

• $ a + 1 $

• $ 2a + 1 $

Solve the equation for h in terms of V, r, and π using the formula for the volume of a cone V = (1/3)πr²h.

• h = 3V/(πr²)

• h = V/(3πr²)

• h = Vπr²/3

• h = 3πr²/V
