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 first step to solve... $5\left|x-2\right|=20$  

• Get absolute value alone by subtracting 5 from both sides

• Get absolute value alone by dividing by 5 on both sides

• Split into two equations

• Distribute the 5 into the absolute value

Solve for the variable F in the following equation: $C=\frac{5}{9}\left(F-32\right)$  (This is the formula converting temperature from Fahrenheit to Celsius.)

•  $F=59​(C+32)$  
  

•  $F=\frac{9}{5}\left(C+32\right)$  
  

•  $F=\frac{9}{5}C+32$  

•  $F=59​C+32$
