Answer:x=20
Step-by-step explanation:
2(3x+1) = 6x+2
since xy and yz are the parts of a midpoint they are equal to eachother
so 6x+2=5x+22
if you subtract 5x from both sides you get x+2 = 22 then you subtract 2 from both sides so you have x=20

Answer:
profit%=35%
Let cp be x
profit =$280
To find cost price of a refrigerator use formula
profit%=profit/cost price *100
35%=$280/x*100
35%=$28000/x
35*x=$28000
x=$28000/35
x=$800
now to find the selling price of a refrigerator use formula
selling price=cost price +profit
=$800+$280
=$1080
Step-by-step explanation:
therefore the cost price of a refrigerator is $800 and selling price is $1080
