4,680 I do it like this 50 percent is 3600 then 10 percent is 720 and 5 percent is 360 add then you get 4,680
650 -136=514
514 divided by 25 = 20.56
So it would be 21
This will give you a little extra chairs but they have to be equal in each row
Answer:
Step-by-step explanation:
6x-21>3
Add 21 to both sides
6x>24
Divide 6 on both sides
X>4
14x+11>-17
Subtract 11 from both sides
14x>-28
Divide 14 on both sides
X<-2
3/4 - 3/5
common denominator is 20
15/20 - 12/20 = 3/20
3/20 is your answer
multiply the opposite denominator with current numerator to get your new numerator number
hope this helps
