one bag contains x pencils
5 bags contain 5x pencils
after adding 3 pencils to each bag
total no of pencils = 5(x+3)
According to question,
5(x+3)=45
x+3=45/5
x+3=9
x=6
one bag contained 6 pencils before adding
Answer:
14
Step-by-step explanation:
so what is a sign of a physical change is occuring
The slope of the line given the points is calculated through the equation,
m = (y2 - y1) / (x2 - x1)
Substituting the known values,
m = (6 - 6) / (-2 - 4) = 0
The slope of the given line is equal to 0 which means that it is a horizontal line.
You cannot eliminate x and end up with two different equations.
5x+3y=9.. B
2x-4=40...A
Solve A for x.
2x - 4 = 40
2x = 40 + 4
2x = 44
x = 44/2
x = 22
The only thing I can think of doing is to plug 22 into B.
5(22) + 2y = 9
110 + 2y = 9...This leads to an answer for y.
No two NEW EQUATIONS is possible.
2y = 9 - 110
2y = -101
y = -101/2
