You can only combine numbers with the same variable
4r - 16r = -12r
5s + 3s = 8s
The answer is -12r + 8s
Hope this helps!
The answer is d 8x^2 - 10
There are 6 apples and 2 oranges.
So the ratio of apples to oranges would be 6:2.
However this can be simplified, because these number have a common factor, which is 2. So you divide 2 by 2, and 6 by 2, and get 1 and 3. So the ratio of apples to oranges in simplified form is 1:3. Hope this explains it :)
The answer is 14.4.................................
