Answer:
≈ 0.1056
Step-by-step explanation:
From the information provided we know that:
of beads are silver
of beads are gold
beds are blue.
The rest are red.
To solve this problem in an easier way we can make the sum all the fractions. In this way we have to:
![\frac{4}{9} + \frac{1}{5} + \frac{1}{4} = \frac{161}{180}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B9%7D%20%2B%20%5Cfrac%7B1%7D%7B5%7D%20%2B%20%5Cfrac%7B1%7D%7B4%7D%20%3D%20%5Cfrac%7B161%7D%7B180%7D)
We know that the rest are red beads
To calculate this fraction we perform the following operation.
![1-(\frac{4}{9} + \frac{1}{5} + \frac{1}{4}) =\ red](https://tex.z-dn.net/?f=1-%28%5Cfrac%7B4%7D%7B9%7D%20%2B%20%5Cfrac%7B1%7D%7B5%7D%20%2B%20%5Cfrac%7B1%7D%7B4%7D%29%20%3D%5C%20red)
![1- (\frac{161}{180}) = \frac{19}{180}](https://tex.z-dn.net/?f=1-%20%28%5Cfrac%7B161%7D%7B180%7D%29%20%3D%20%5Cfrac%7B19%7D%7B180%7D)
The expression that gives the best estimate of the fraction of red beads that Julia has is:
![1-(\frac{4}{9} + \frac{1}{5} + \frac{1}{4}) = \frac{19}{180}](https://tex.z-dn.net/?f=1-%28%5Cfrac%7B4%7D%7B9%7D%20%2B%20%5Cfrac%7B1%7D%7B5%7D%20%2B%20%5Cfrac%7B1%7D%7B4%7D%29%20%3D%20%5Cfrac%7B19%7D%7B180%7D)
Answer:

As a decimal
Step-by-step explanation:
Answer: f(x) = 8x -1
Step-by-step explanation:
( f + g )x = 3x + 5x + 8 - 9
( f + g)x = 8x - 1
Answer:
I think it is C-D.
Step-by-step explanation:
Answer:
dogs - 13
cats - 39
Step-by-step explanation:
Let the number of dogs Ma Bernier have be represented with d
She has 3 times as many cats as dogs, the number of cats she has :
cats = 3d
The sum of the cats and dogs is 52
d + 3d = 52
4d = 52
divide both sides of the equation by 4
d = 13
She has 13 dogs
Cats = 3d
= 3 x 13 = 39
