The mass of a freight train is 9.98 • 10^6 kilograms. the mass of an aircraft carrier is 7.3 • 10^7 kilograms. approximately how many more kilograms is the mass of an aircraft carrier than the mass of freight train? show your work and write your answer in scientific notation.

Train: 9.98 x 10^6 = 9,980,000 kilograms

Aircraft carrier: 7.3 x 10^7 = 73,000,000 kilograms

Subtract:

73,000,000 - 9,980,000 = 63,020,000 kilograms.

Written in scientific notation: 6.3 x 10^7

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

the line of
