Mr. Adams had 24 guests at his house for a party. Each guest brought one item. One-third of the guest bought drinks, one-fourth of the guest brought dessert, the rest brought chips. How many guest brought drinks?

8 guests brought drinks

Step-by-step explanation:

Given;

- 24 guests total

- 1/3 brought drinks

- 1/4 brought dessert

- rest brought chips

Find;

- how many brought drinks

To solve this problem, all one has to do is multiply the fraction of guests who brought drinks by the total amount of guests.

1/3 * 24

= 8

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
