Mainly all you do is subtract , and it'll give you the right estimate
2x - 3 = y
-3x + 5 = y
-4/5x -2 =y
1/2x + 9 = y
Answer:
x = 6
Step-by-step explanation:
(segment piece) x (segment piece) = (segment piece) x (segment piece)
2*x = 3*4
2x = 12
Divide each side by 2
2x/2 = 12/2
x = 6
Well,
If the slope of the lines are the same, then the lines are parralel.
We need to manipulate 2y - 10x = 4 into y = mx + b form.
Add 10x to both sides
2y = 10x + 4
Divide both sides by 2
y = 5x + 2
Do the same thing with the other equation.
Add 2 to both sides
y = 5x + 2
y = 5x + 2
It appears that, not only are they parallel, but they lie on exactly the same line! If this was a System of Simultaneous Linear Equations, then there would be an infinite number of solutions!<span />
Well if packs and boxes cost the same then you can get either one 27 times: 27 * 10 = 270. Then you can get 6 singles to equal 276.
