Which algebraic expression represents

"six less than a number"?

• $\frac{6}{k}$

• $\frac{k}{6}$

• $6-k$

• $k-6$

Translate this phrase into an algebraic expression.
2 times the difference of m and 11

•  $2\left(m+11\right)$  

•  $2\left(m-11\right)$  
  

•  $2\left(\frac{m}{11}\right)$  
  

•  $2m-11$  

A holiday meal cost $12.50 a person plus a delivery fee of $30. Which equation represents the amount a holiday meal costs(y), including delivery, for x people?

• y = 12.50 + 30x

• y = 12.50 + 30

• y = 30 + 12.50x

• 12.50x = 30

Evaluate -2x + -3y if x = 10 and y = -6

• 18

• 12

• -38

• -2

• 8

• 10

• 9

• 11

What is the first step when solving this equation:

r - 18 = 27

• Subtract 18 from both sides of the equal sign

• Add 18 to both sides of the equal sign

• Multiply both sides of the equal sign by 18

• Divide both sides of the equal sign by 18

 $16=\frac{k}{11}$  
The variable, k, is being divided by 11.  Of the choices, how could you show your work to solve for k?

• Divide both sides by 11

• Add 11 to both sides.

• Multiply both sides by 11.

• Subtract 11 to both sides.

 $\frac{x}{-11}+8=6$  

  

•  $x=-22$  

•  $x=1$  

•  $x=11$  

•  $x=22$  

 $14x-10=4$  

•  $x=-8$  

•  $x=10$  

•  $x=1$  

•  $x=-14$  

2x - 3 + 4x = 27
