• Multiply the term outside the parenthesis with each term inside the parenthesis

• Non of the above

what is the second operation you use while solving the following equation? $4\left(x-3\right)=20$  

• multiplication

• addition

• opening bracits

• division

what is the purpose of using the distributive property while solving equations?

A group of friends buys 5 waffles and some cookies that costs $2.5 per piece. The total cost is 97.5 .Let x represent the price of one waffle. choose an equation to represent this situation.

• 5 (x+2.5) = 97.5

• x (5+2.5) = 97.5

• 5 (x+97.5) = 2.5

A quarter of the sum of a number and 40 is equivalent to 17. Which equation matches the statement ?

• 4n (n+40) =17

• 1/4 (n+17) =40

• 1/4 (n+40) =17

solve the following equation:  $-4\left(x-5\right)=18$  

• x= -9.5

• x= 8.5

• x= -1.80

• none of the above

solve the equation: -4 (6-d) =4

• d= -7

• d= -5

• d= 5+6

solve the equation: 2/5 (x-23.50) =13.80

• x=-11

• x=11

• x=5

solve the equation: 11 (6.40+4.80+f) =128.15

• f= -0.45

• f= 0.45

• f= 0.54

choose the equation that represents this value of x: x=7.5

• -8 (0.5x-3) =3

• 11 (x+3) =4

• 18 (4+x) =207
