Answer:
3 2/3
Step-by-step explanation:
7 1/3 =22/3
3 2/3= 11/3
22-11= 11
11/3= 3 2/3
Answer: 4.8 liters
Step-by-step explanation:
Let x liter of water is added with y liter of 25% beach solution.
Thus, According to the question,
x + y = 12 -------(1)
0% of x + 25 % of y = 15 % of 12
25 % of y = 15% of 12



Put this value in equation (1),
We get,




Therefore, the quantity of water = 
And, the quantity of 25% bleach solution = 
<span>Solve the system
9x = 27-9y
20x=71-9y
Let's use the "elimination through addition/subtraction method.
Multiply the first equation by -1 so as to obtain +9y:
-9x = -27 + 9y
</span><span>20x= 71- 9y
--------------------
Add these 2 equations together:
</span>-9x = -27 + 9y
20x= 71- 9y
--------------------
<span> 11x = 44
Solve this for x: x = 44/11 = 4.
Now find y by subst. 4 for x in either of the original equations.
Using the second equation: </span><span>
</span>20x=71-9y
20(4) = 71 - 9y
80-71 = -9y
9 = -9y. Then y = -1.
The solution set is (4,-1).
You would divide 76 by 8. That would give you 9.5. Then you multiply by 10 and that gives you 95. Hope this helps (;
