Complete each equation with a number that makes it true. 8=40 8+=40 21=7 21−=7 21=7

8*5 = 40   8+32 = 40   21/3 = 7   21-14 = 7   21/3 = 7

Step-by-step explanation:

40/8 = 5

8 + x = 40    40-8 = x = 32

21x = 7  x = 7/21 = 1/3

21 - x = 7   21 - 7 = x = 14

21x = 7  x = 7/21 = 1/3

blank one is 5

blank two is 32

blank three is 3

blank four is 14

blank five is 3

$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
