Carol Is 5 Times As Old As Her Brother She Will Be Three Times As Old As Her Brother In Two Years How Old Is Carol Now

carol is 5 times as old as her brother she will be three times as old as her brother in two years how old is carol now

  Let x be the age of Carol
y be the brothers age
x=5y ---equation 1
x+2=3(y+2) ---equation 2
substitute equation 1 to 2
5y+2=3y+6
5y-3y=6-2
2y=4
y=2
substitute to equation 1
x=5y
x=5(2)
x=10
therefore Carol is 10yrs old

A container of gas is initially at 0.500 atm and 25 ˚C. What will the pressure be at 125 ˚C? Solution po hehe Thankyouu   Hello! A container of gas is initially at 0.500 atm and 25 ˚C. What will the pressure be at 125 ˚C ? We have the following information: P1 (initial pressure) = 0.500 atm T1 (initial temperature) = 25ºC (in Kelvin) TK = TºC + 273.15 → TK = 25 + 273.15 → T1 (initial temperature) = 298.15 K P2 (final pressure) = ? (in atm) T2 (final temperature) = 125 ºC (in Kelvin) TK = TºC + 273.15 → TK = 125 + 273.15 → T2 (final temperature) = 398.15 K   According to the Law of Charles and Gay-Lussac in the study of gases, we have an isochoric (or isovolumetric) transformation when its volume remains constant or equal, then we will have the following formula:   Answer: The pressure is approximately 0.668 atm ________________________________   I Hope this helps, greetings ...
