Heath needs to end up with 10L of solution,
of which 9L is bleach. So let m = liters of 20%
solution needed. Then .20m liters of that are bleach.
He must then add p liters of bleach to make
a total of 10 L. That is, p + m = 10. So the system is
m + p = 10, .20m + p = 9. Solving,
<span>m = 1.25 L 20% solution, and thus p = 8.75 L bleach.</span>
Hey there,
The word problem is as follows:
- t multiplied by 52 is the same as 349
In numbers this would mean t x 52 = 349. Now to solve for t we would do the opposite of multiplication which is is division.
So...
- 349 ÷ 52 = t and t = 6
The answer would be t is equal to 6 and or 6.712
Hope I helped,

1000 is the missing exponent
Answer:
81
Step-by-step explanation:
from 4 to 5,the difference is 1 ,and when you multiply by 3, then add 3 to 5 ,it gives you 8 ,to get 17,I multiple 3by 3 and add the answer to 8 ,and the same continues upto when you get the final answer which is 81.
difference is just multiplying the previous difference with 3 and add it with the previous number .
It would be 0.95 you judt divide the top jumberto thebottom one
