Answer:
3 beverages, 5 appetizers, 8 entrees, and 4 desserts.
Step-by-step explanation:
I think you meant 20 items, so let's do that. To find 15% of 20, we multiply 20 by .15. This gets us 3. We repeat this with all the other numbers, using different decimals, of course. We get 3 beverages, 5 appetizers, 8 entrees, and 4 desserts. 3 + 5 + 8 + 4 is 20, so everything checks out.

Answer:
For the first one, the answer is 20.82
Step-by-step explanation:
you first add 2.65 to 2.56 and then add 5.9 to 5.9 and you add them together and you get 16.92 and then you subtract it from 37.74
also for the second one I don't understand. could you be a little more clear?
Answer:
400.00
Step-by-step explanation:
20*20 is close to 2*2. Since we have zeros, we can multiply 2 and 2 to get 4. Then we add two zeros because of the zero in 20 and the zero in the other 20. This could also be written as because we're multiplying 20 by itself.
Answer:
12x^3+15x^2-12x+12
Step-by-step explanation:
P(x) = 12x^3 + 11x^2 - 9x + 10
Q(x) = 4x^2 – 3x + 2
P(x) + Q(x) = 12x^3 + 11x^2 - 9x + 10+ 4x^2 – 3x + 2
Combine like terms
=12x^3+11x^2+4x^2-9x-3x+10+2
=12x^3+15x^2-12x+12
