Use the distributive property to rewrite each algebraic expression: do not solve, just rewrite.

1) 8(x + 7) =

2) 5(x - 10) =

3) 6(11 + x) =

factor each expression. (pull a common factor from each number)

completed example: 27 + 12 = 3(9 + 4) → (3 is the shared factor for 27 and 12)

4) 12 + 36 =

5) 16 + 20 =

solve each expression using the distributive property.

6) 4 x 82

7) 12 x 44

8) mrs. s bought 9 folders and 9 notebooks. the cost of each folder was $2.50. each notebook cost $4. first, write an expression for the problem then find the total cost.

expression =

total cost =

Use the distributive property to rewrite each algebraic expression: Do not solve, just rewrite.

1) 8(x + 7) = 8x + 56

2) 5(x - 10) = 5x - 50

3) 6(11 + x) = 66 + 6x

Factor each expression. (Pull a common factor from each number) 

COMPLETED EXAMPLE: 27 + 12 = 3(9 + 4) → (3 is the shared factor for 27 and 12)

4) 12 + 36 = 12 (1 + 3)

5) 16 + 20 = 4 (4 + 5)

Solve each expression using the distributive property.

6) 4 x 82 = 4 (80 + 2) = 320 + 8 = 328 

7) 12 x 44 = 12 (40 + 4)  = 480 + 48 = 528

8) Mrs. S bought 9 folders and 9 notebooks. The cost of each folder was $2.50. Each notebook cost $4. First, write an expression for the problem then find the total cost.

Expression = 9f + 9n = 9($2.50) + 9($4)

Total cost =9($2.50) + 9($4) = $22.5 + $36 = $58.5

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
