Arestaurant made 16.5 gallons of tea. the first hour the restaurant was opened, 3.4 gallons of tea were served. the second hour, 6.9 more gallons of tea were serve. how much tea was left after second hour? plz show work: )

a. 13.1 gallons
b. 10.3 gallons
c. 6.2 gallons
d. 4.3 gallons

C

Step-by-step explanation

16.5-3.4=13.1

13.1-6.9=6.2 gallons

6.2 gallons of te

Step-by-step explanation:

first you are going to take the initial amount of tea that you had in the beginning which was 16.5

second you are going to subtract the 3.4 gallons that were served int the first hour, which will leave you with 13.1 gallons of tea

next you subtract the other 6.9 gallons served in the second hour, leaving you with 6.2 gallons of tea

so 6.2 is what you would have left after the second hour :)

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
