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.
Answer:
(-4, -3)
Step-by-step explanation:
First divide the second equation by -1. It becomes y = -3x - 15.
Then, substitute this equation into the y of the first equation.
x + 2(-3x - 15) = -10
x - 6x - 30 = -10
-5x = 20
x = -4
Then substitute the x value into the equation x + 2y = -10
-4 + 2y = -10
2y = -6
y = -3
Answer:
Ok, she walks 3 miles to and from the library.
So in total, she walks 3 miles two times, then in one week, she walks 2*3mi = 6miles.
She says that she walked about 300 miles in total.
We must see if 300 miles is a multiple of 6 miles.
300mi/6mi = 50.
This means that she would walk about 300 miles since she started counting if she went to the library and back home exactly 50 times (again, since she started counting).
And she does this once a week, then if she started counting 50 weeks ago, then it is possible,
