Joe and Sam shared a cheesecake cut into 12 pieces Joe ate three pieces and Sam ate five pieces what faction of the cheesecake did they eat in all show how you find your answer ​

Step-by-step explanation:

Just simply add along the top of the numbers.

1. We know that there were 12 pieces and out of those 12 Joe ate 3 pieces and Sam ate 5.

2. So now we have the two fractions and we simply add them together by adding across the top, we do not need to make any changes to the denominator due to the fact that they are parts of the 12 pieces of pie

3. after adding 3 + 5 you should get 8 and since the denominator will remain the same the answer should be

4. Now we must simplify we know 8 ÷ 4 = 2 and we can also divide 12 by 4 and that gets us 3 so make the numbers into a fraction, 3 should be on the bottom, and two on the top, and when you have your final answer your work should look somewhat similar to this:

when x=3: answer is 1

when x=0: answer is 1

when x=5: answer is 1

Step-by-step explanation:

Substitute the given value into the function and evaluate.
