2. Sarah has some blue marbles, twice as many red marbles as blue, and 8 yellow marbles. If she has a total of 32 marbles, how many red marbles does she have?
A.8
B.12
C.16
D.24

Given:

Number of  blue marbles, twice as many red marbles as blue, and 8 yellow marbles.

She has a total of 32 marbles.

To find:

The number of red marbles.

Solution:

Let number of blue marbles be x.

Then, number of red marbles = 2x

Number of yellow marbles = 8

Total number of marbles = 32

Now,

Number of red marbles

Therefore, there are 16 red marbles.

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
