X = (w + y + z) / 4....multiply both sides by 4, cancelling the 4 on the right
4x = w + y + z ....subtract w and subtract z
4x - w - z = y....answer is A
The answer is 1 inch equals 8
0.486 % of world population lives in canada
<em><u>Solution:</u></em>
From given,
World population = 7691 million
Canada population = 37.4 million
We have to find the percent of world population lives in canada
Let "x" be the percent of world population lives in canada
Therefore, from question,
x % of world population = canada population
x % of 7691 = 37.4
<em><u>Solve the above equation for "x"</u></em>

Thus 0.486 % of world population lives in canada
Answer:



Step-by-step explanation:
The given equation is 
We substitute the ordered pairs to see which ones satisfies the equation.
For (-1,-8), we put x=-1 and y=-8 to get:


This is not true.
For
we put x=-1 and
to get

This is true
For (3,3/2) we have 2(3)+6(3/2)=15
This implies 6+9=15
15=15
This is also True
For (-5,25/6), we have 2(-5)+6(25/6)=-10+25=15
This is also true.
