Question

x + y/y=4 and x+z/z=6, what is the value of y/z?
A) 3/5
B) 2/3
C) 1
D) 3/2
E) 5/3

Answer 1

any explaination :o?

Answer 2

It's simple algebra. We have:
\[(x+y)/y=4\]and\[(x+z)/z=6\]Now solve for both y and z:
\[x/4+y/4=y\]and\[x/6+z/6=z\]Then:\[x/4=(3/4)y\]and\[x/6=(5/6)z\]Isolate:\[x/3=y\]and\[x/5=z\]Finally, divide:\[(x/3)/(x/5)=5x/3x\]Check on my algebra; I did this in notepad...

Answer 3

Lala do u know this? To graph the inequality y > 5x - 4, you would draw a solid line.

A. True
B. False

Answer 4

B

Answer 5
