Answer:
Step-by-step explanation:
The point-slope form of a line is given as:
Where
m is the slope
is the x-coordinate of the point given (passing through the line)
is the y-coordinate of the point given (passing through the line)
Now,
Given,
Slope = m = 3
= 1
= 2
Now, we simply plug these into the formula for point-slope form of a line:
This is the point-slope form.
The standard algorithm is the way or steps to find an answer.
You will need 252 mL of pure water to obtain 0.25 mL of the desired 25% solution.
If we add X amount of water to the solution, the total amount of solution is 375+X.
And that must be 25%.
<h3>
What is the amount of solute in the current solution?</h3>
The amount of solute in the current amount of solution is
0.6(375)=225.
That amount won't change by adding water.
So we set up the equation so that the amount of solute divided by the new total amount of solution equals 25%.
225/(375+X)=0.25
cross multiply and solve
225/0.25=(375+X)
900-375=X
X=525
The pure water will you need to add to obtain the desired solution is 525.
Then we check 225/(375+525)=0.25.

Step-by-step explanation:
Answer:
The answer is 7/6x - 75.
Step-by-step explanation:
17 - 1/5x +2/3x - 92 + 7/10x
17 - 6/30x + 20/30x - 92 + 21/30x
-6/30x + 20/30x + 21/30x = 35/30x or 7/6x
17 - 92 = -75
7/6x - 75
