Answer:
correct / incorrect / incorrect
Step-by-step explanation:
5a - 8 + 2a² + 2a - 1 ← collect like terms
= 2a² + 7a - 9 ← correct
-------------------------------------
b² + 6b - 4 - (3b + b²) ← distribute parenthesis by - 1
= b² + 6b - 4 - 3b - b² ← collect like terms
= 3b - 4 ≠ 2b² + 3b - 4
---------------------------------------
9c - 4c² - (2c² + c) ← distribute parenthesis by - 1
= 9c - 4c² - 2c² - c ← collect like terms
= - 6c² + 8c ≠ - 6c² + 10c
Answer:
5.5 gallons if the guests only drink 2 cups
Step-by-step explanation:
There are 16 cups in 1 gallon
There are 20 guests
Each guest will drink 2 cups
20*2=40
40 cups is equivalent to 2.5 gallons
You then take the original 8 gallons and subtract 2.5 from 8 and you get the answer
Divide 4 and 5/8 by 5/8. you will get 7 and 2/5, or 7.4. since this you need whole pieces of wood, round down to 7.
final answer=7 pieces of wood
