August hosted two dinner parties for his friends. twenty-five guests attended the first party, and thirty-one guests attended the second party. what is the percentage increase of the number of guests from the first party to the second party?

 The percentage increase of the number of guests from the first party to the second party is 24 %.

Step-by-step explanation:

Hi, to solve this problem we have to calculate the increase of guests in numbers.

31 guests from the second party

25 guests from the first party

31-25 = 6

Now, we have to calculate the percentage of that number.

25 / 6 =  0.24

And finally, multiply it by 100 to express in percentage

0.24 x 100 = 24 %

The percentage increase of the number of guests from the first party to the second party is 24 %.

Feel free to ask for more if it´s necessary or if you did not understand something .

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
