The mass of the Earth is about 6,000,000,000,000,000,000,000,000 kg. The mass of a human brain is about 1400 grams SHOW ALL WORK (a) What is the mass of the Earth written in scientific notation?
(b) What is the mess of a human brain in scientific notation?
(c) in comparing the measurements in Parts (a) and (b), what else must be done before a comparison is made

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
