Okay, the first equation you have to use is 3x + 10y = 50 because when you add all these weights up (3 lb weights, represented by 3x, and 10 lb weights, represented by 10y), you get 50 lbs.
As you can see, there is no such equation here. But, if we move things around a bit, we get:
3x + 10y = 50
3x = 50 - 10y

The correct answer is B. 3x = 50 - 10y

"everyday

use" was written by alice walker. this is a story about two sisters, dee

and maggie wanting to have the handmade quilt. maggie wants to use the thing

for its purpose, while dee appreciates it for being “her heritage”. the quilt represents family heritage. it was

believed that only dedication and years of hard work can represent a quilt.

mama decided to give

the quilts to her less fortunate daughter, maggie because she believed that dee

could not hold the true meaning of their family heritage and that she would not use the quilts for their

purpose. however, dee believed that maggie can’t appreciate the quilts just as

how she sees them, and she thought that the quilt will be put to “everyday use”

by maggie and within 5 years or so, the quilt will turn into a rag. in the story, dee strongly believed that maggie do not deserve the quilts.

explanation:

have a great day!

Answer from: Quest

animal farm, written by george orwell, is a representation of russia after the revolution that led stalin to take over power.

in this excerpt, the central idea seems to be that the animals (a representation of society), when they believe to be working for a greater good and equality, are obedient and productive. they were convinced that, after expelling the owner (jones) from the farm, they would live in harmony and be fairly treated.

as we know, the pigs become the leaders and grow more selfish and dictatorial with time. in the end, they look and act in a way so similar to humans that it is impossible to tell the difference. the ideals of equality are shattered, and the farm turns out to be worse than it was before. the animals are manipulated with false propaganda and forced to work in order to enrich the pigs.
