(15(.17)+.29x)/(15+x)=.23
2.55+.29x=3.45+.23x
.06x=.9
x=15
So 15L of the 29% solution was added to the 15L of 17% solution to make
30L of 23% solution.

Hope this helps and sorry if wrong!
Hello there! As far as we can see, the y-intercept is 2. Going up 2 helps move the line up by 2. We can go ahead and eliminate C, because that equation only goes up one, and D, because we don't go down any. We have the points (1, 3) and (2, 4). We add the x-value and we can see that 1 + 2 is 3 and 2 + 2 is 4. The only equation that fits the line at all is A. Therefore, the answer is A.

Answer:
8
Step-by-step explanation:
The number of days has gone down by a factor of 15/24. The number of workers is inversely proportional, so must increase by a factor of 24/15 = 8/5.
(5 workers) × (8/5) = 8 workers
8 workers are needed to complete the project in 15 days.
B is the answer have a g00d day
