Answer: Option B
B. 
Step-by-step explanation:
We have the following equations:
(1)
(2)
Let us call "a" the coefficient of the variable x in the first equation and call "b" the coefficient of the variable x in the second equation.
Then we must multiply the number "a" by a value z such that when adding
the result is zero.

So

We solve the equation for z


The first equation must be multiplied by a value of 
2/6 + 2/6 + 2/6
1/6 + 5/6
4/6 + 2/6
In this problem, you need to figure out whats 23% of 29% to find the percentage of the total group becoming vegetarians.
In order to do this, you can convert the percentages to decimals and multiply.
.23 x .29 = .0667 or 6.67%
6.67% of the total group are considering becoming vegetarians.
5.2 is less because it's a lower number and still a decimal
Answer:
The perimeter of a rectangle is:
Step-by-step explanation:
Given
The width of a rectangle w = 8n - 8.5 feet
The length of a rectangle l = 8.5n + 10 feet
To determine
The perimeter of a rectangle = P = ?
The perimeter of a rectangle can be determined using the formula

substitute l = 8.5n + 10 and w = 8n - 8.5




Therefore, the perimeter of a rectangle is:
