(x+2/5)7=63/10
then divide both sides by 7
x+2/5=63/70
subtract 2/5 from both sides
and x= 1/2
*x=original number

Multiply both sides of the equation by 12

<span>14100000 written in scientific notation would be 1.41 x 10^7 because you have to make the number be between 1 and 10, so you would put your decimal between the 1 and 4, then you would count the number of zeros in standard form, then you would solve and your answer would be 1.41 x 10^7</span>
The answer to the equation is 5 7/15
