or n + 10
it shows 10 more than a number
Answer:
The answer would be 8.3*10^7.
Step-by-step explanation:
This is because the beginning factor in scientific notation (in this case it is 8.3) must be no less than one, and no more than ten. Once we figured that out, we simply count the number of decimal points from 3 to the final 0. Try it yourself. You will discover that the resulting answer is 7 decimal movements. Now, since we are using scientific notation, we will want to multiply by ten to the power of the number of decimal movements (in this case it is 7.) And that's all! The answer is 8.3*10^7. I hope this helped (:
The best approach would be to subtract 6 from both sides of the equation for the first equation
5x = y + 6
5x - 6 = y
Therefore the y is isolated so you can substitute that into the second equation
2x - 3(5x -6) = 4
