Geometry math question no guessing and show work you

Here for AB to be parallel to CD, alternate interior angles must be equal,

2x+40=3x+10

3x-2x=40-10

x=30

so if x =30 , it will make AB parallel to CD

Option D , x=30 is correct

$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
