Draw a graph of y=4x, and the x-coordinates of the points of intersection, if I’m not mistaken, are the answers.
8m - 5n + 2m + 6n =Simplifying
8m + -5n + 2m + 6n = 0
Reorder the terms:
8m + 2m + -5n + 6n = 0
Combine like terms: 8m + 2m = 10m
10m + -5n + 6n = 0
Combine like terms: -5n + 6n = 1n
10m + 1n = 0
Solving
10m + 1n = 0
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-1n' to each side of the equation.
10m + 1n + -1n = 0 + -1n
Combine like terms: 1n + -1n = 0
10m + 0 = 0 + -1n
10m = 0 + -1n
Remove the zero:
10m = -1n
Divide each side by '10'.
m = -0.1n
Simplifying
m = -0.1n.
So first we add up all the marbles. Which would be 25. Then we look to see how many red marbles there are. There are 5. You have a 5/25 chance of drawing a red marble. But you can reduce that. So when it's all said and done you have 1/5 chance of drawing a red marble.
Hope this helps!
The percentage of profit margin that
the plumbing supplies manager realizes that he has = 15%
Total sales for the month made by the plumbing supplies manager = $23000
Then
Amount of profit that has been made
by the plumbing sales manager = 15% * 23000 dollars
= (15/100) * 23000 dollars
= 15 * 230 dollars
= 3450 dollars
So the plumbing manager makes a profit of $3450 in the month as can be seen from the above deduction.
