Answer:
1/3
Step-by-step explanation:
when the party started he cake was 3/3 after the party it was 2/3 so they ate one slice/third and now Elisa ate 1/3 one (one Third) so now there is 1/3 left of the cake ( subtracting fractions)
Answer:
3 1/100
Step-by-step explanation:
That is just the answer
I believe you are expected to simplify. To do this all you do is group like terms (x, x², x³ etc.) and then simplify the coefficients.
13. 10z + 7z - 19z² - 5z² - 17z
first you can rearrange and group like terms (remember the bring the sign in front of each term with it). I would do it like this:
-19z² - 5z² +10z + 7z - 17z
Now simplify the coefficients:
-24z² + 0z
you can omit the 0z and your simplified answer is
-24z²
Main thing to remember here is that z and z² cannot be simplified together, nor can any variable that has an exponent because the exponent makes them differ.
Divide 1 by the amount of pieces... 1/10
