use 2 mathematical properties to change 9(8j + 2 + j) into one expression ( show work)

Original equation: 9(8j + 2 +j)

1st use Distributive property:

Multiply 9 by each term in the parenthesis:

72j + 18 + 9j

2nd use Addition Property to combine like terms:

81j +18

c. (0.6,-1.4)

step-by-step explanation:

hope this

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
