Answer:
10
Step-by-step explanation:
We will use a system of equations to solve this. We do not know how much of the 25% bleach solution is used; we will use x to represent this. We know that 5 cups of the 10% solution was used. We do not know how much of the resulting solution we have; we will use y to represent this. This gives us the equation
x+5 = y
Using the decimal forms of the percentages for each solution, we have 0.25x (25% solution for x cups), 0.1(5) (10% solution for 5 cups) and 0.2y (20% solution for y cups); this gives us the equation
0.25x+0.1(5) = 0.2y
This gives us the system

To use elimination, we will make the coefficients of x the same by multiplying the top equation by 0.25:

We will now subtract the second equation from the first:

Divide both sides by 0.05:
0.75/0.05 = 0.05y/0.05
15 = y
There were 15 cups of the resulting 20% solution. Substituting this into the first equation, we have
x+5=15
Subtract 5 from each side:
x+5-5=15-5
x = 10
Find 7% of 5000 students ?
Answer :

<u>So, 7% of 5000 students is 350 students.</u>
To Match
To isolate -1 we need to subtract 2m from both sides
2m - 1 = 3m (SUBTRACT 2m)
To isolate 1 we need to subtract m from both sides
2m = 1 + m (SUBTRACT m)
To isolate m we need to add 1 from both sides
m - 1 = 2 (ADD 1)
To isolate m we need to subtract 2 from both sides
2 + m = 3 (SUBTRACT 2)
To isolate m we need to add 2 from both sides
-2 + m = 1 (ADD 2)
To isolate m we need to subtract 1 from both sides
3 = 1 + m (SUBTRACT 1)
