It took 35 minutes for 45 people to pass through customs at the airport. if it takes the same amount of time for each person, how long will it take for the whole plane of 135 people to pass through customs?

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

answer: -0.5 would be the most likley outcome
