What is the distance from the directrix (the Crocodile River) to the point (x,y)? Write this equation. Your answer will contain a y-term.It also is the X And Y and the crocodile river it is about 1939 feet
Y = number of yellow marbles
r = number of red marbles
The total number of marbles
y+r=61
The number of yellow marbles compared to red.
y=2r+4
Substitute the second equation into the first equation because they are the same variable and, therefore, are the same number.
2r+4+r=61
Simplify
3r+4=61
Subtract 4 from both sides
3r=57
Divide both sides by three
r=19
We have the number of red marbles, but we are looking for the number of yellow marbles, so plug the 19 red marbles into either equation.
y=2(19)+4
or
y+19=61
Simplify
y=42

Solution:
we are given that
In the library at Lenape Elementary School, there are 3/8 as many fiction books as there are nonfiction books.
There are 44 books in the school library.
we have been asked to find How many books are fiction books?
Let there are x non fiction books in the library. Then there will be
fiction books.
Hence we can write
![x+\frac{3}{8}x=44\\\\\text{Now solve for x}\\\\\frac{8x+3x}{8}=44\\\\\frac{11x}{8}=44\\\\11x=44*8\\\\x=\frac{44*8}{11}\\\\x=4*8=32\\](https://tex.z-dn.net/?f=%20x%2B%5Cfrac%7B3%7D%7B8%7Dx%3D44%5C%5C%5C%5C%5Ctext%7BNow%20solve%20for%20x%7D%5C%5C%5C%5C%5Cfrac%7B8x%2B3x%7D%7B8%7D%3D44%5C%5C%5C%5C%5Cfrac%7B11x%7D%7B8%7D%3D44%5C%5C%5C%5C11x%3D44%2A8%5C%5C%5C%5Cx%3D%5Cfrac%7B44%2A8%7D%7B11%7D%5C%5C%5C%5Cx%3D4%2A8%3D32%5C%5C%20%20%20%20%20)
Hence there are 32 non-fiction books in the library.
and 44-32=12 fiction books in the library.
Answer:
see the procedure
Step-by-step explanation:
we know that
![1.8=1+0.8](https://tex.z-dn.net/?f=1.8%3D1%2B0.8)
![486=400+80+6](https://tex.z-dn.net/?f=486%3D400%2B80%2B6)
so
The value of digit 8 in 1.8 is 0.8
The value of digit 8 in 486 is 80
Divide the numbers
80/0.8=100
therefore
The value of the digit 8 in 486 is 100 times greater than the value of digit 8 in 1.8
or
The value of the digit 8 in 1.8 is 100 times less than the value of digit 8 in 486
Answer:
0.535 prefer chocolate and 0.465 prefer vanilla
Step-by-step explanation:
So starting off with chocolate. 200 people were surveyed. So 100 people would be 0.50 (or half or 50%). So 107 people who prefer chocolate would be a bit more than 0.50. 0.535 prefer chocolate.
Going to vanilla, 93 people prefer it. this is LESS than half so it has to be under 0.50. There is only one that is less than 0.50, which is 0.465. Also using addition, this would be the only logical one.
