3) Solve the following equations by starting with the indicated step. Remember that as long as we do the same operation to both sides of the equation it will stay balanced and result in the same answer. 2x + 4 = 6X-8 Subtract 4 from both sides Add 10 to both sides Divide both sides by 2 More Tools a) Which first step was the easiest one for you to start with? Justify your answer with a complete sentence.​ [not physics algebra 1 ].

e/c, where e is its total energy

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
