Answer:
y = 4/3x - 4
Step-by-step explanation:
you are given b
so y = mx -4
you can look at the graph and see the slope from there. like the y-intercept and the x-intercept
(0,-4) and (3,0)
slope formula is y2-y1/x2-x1
and so you do -4-0/0-3
-4/-3.
so your slope formula would be
y = 4/3x - 4
So lets say that this salt and water solution consists of 100 liters.
Then that means 20 liters is salt, and 80 liters out of the 100 is water.
Now, we remove 25% of the water. 25% of 80 liters is 20 liters. So, we are left with 80-20, or 60 liters.
Now in all we have 20 liters of salt, and 60 liters of water.
The percentage of salt in the new mixture will be 20/(20+60) = 20/80 = 25%.
Your answer is 25%

Answer:
n=4
Step-by-step explanation:
Of means multiplying so,
×32=24
Multiply by n on both sides to get rid of the n denominator.
3×32=24n
Simplify the equation.
96=24n
Divide by 24.
n= 4
