Elena wants to add (2.3×105)+(3.6×106) and writes (2.3×105)+(3.6×106)=5.9×106. Find Elena's mistake and fix it. The correct answer (in scientific notation) should be:

Question doesn’t make sense

Step-by-step explanation:

The way this question should be written to be correct scientific notation is 2.3x10^5 + 3.6x10^6 which would equal 3.83x10^6

The correct answer is 623.1 . Elena wrote the wrong numbers and put (5.9 x 10^6) .

Step-by-step explanation:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
