How do you combine #5/w+8/-w#?

Answer 1

See the solution process below:

To add fractions they must have a common denominator.

To get the second fraction over a common denominator with the first fraction we must multiply it by the appropriate form of #1#:

#5/w + ((-1)/-1 xx 8/-w) ->#

#5/w + ((-1 xx 8)/(-1 xx -w)) ->#

#5/w + (-8)/w ->#

#5/w - 8/w ->#

#(5 - 8)/w ->#

#(-3)/w ->#

#-3/w#

To combine the expressions 5/w and 8/-w, we need to find a common denominator. The common denominator for w and -w is -w.

To combine the fractions, we multiply the numerator and denominator of the first fraction (5/w) by -1, which gives us -5/-w.

Now, we can add the two fractions together: -5/-w + 8/-w = (-5 + 8)/-w = 3/-w.

Therefore, the combined expression is 3/-w.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
