solve for R

pV = nRT

• R= pV/nT

• R= p/n + V/T

• R= pV - nT

• R= (pV-n)/T

Solve for y

x = 3y - 24

• y = (x + 24)/3

• y = x/3 + 24

• y = 3x + 24

• y = 3(x + 24)

Solve for y

-4x + 2y = -6

• y = -2x + 3

• y = 2x + 3

• y = 2x - 3

• y = -2x - 3

What's a way to define absolute value?

• The value of a number
• The opposite of a number
• The distance of a number from zero
• The multiplicative inverse of a number

What is the reason that absolute value is always written as a positive?

• Absolute value is talking about numbers so it must be positive.
• Absolute value does not always have to be positive.
• Absolute value is like a clock it has only positive numbers.
• Absolute value is talking about distance, distance is always measured by positive numbers.

Solve the absolute value equation. 

• x=7

• x=-7; x=7

• x=-7
