Since they are consecutive, we can define the two unknowns with ease.
The left page (has a smaller value) can be defined as X, and the right page can be defined as X+1.
So,
X + (X+1) = 293
2x+1 = 293
2x = 292
x = 146
So, as we defined before, the smaller page number is equal to x. Therefore, the smaller page number is 146, and the larger page number is 147.
Answer:
Since while finding a percent change i.e. to find the percent increase or decrease in the quantity the old value or we can say the original value plays a vital role.
<em>" Because Percentage Change is all about comparing old to new values "</em>
If we do not know the original value then there is no means of comparing the new quantity, the new quantity is to be measured with respect to the old quantity.Hence, the original quantity is to be kept in the denominator.
1) First: work out the difference (increase) between the two numbers you are comparing.
2) Increase = New Number - Original Number.
3) Then: divide the increase by the original number and multiply the answer by 100.
4) % increase = Increase ÷ Original Number × 100.
It would be 11 + 12 = 23 atomic mass units.
(electrons have about a mass of 5.489×10−4<span> atomic mass units, so their mass would be negligible in this calculation).
