Answer:
50% of the solution
Step-by-step explanation:
25% of 100 ml = 25
added to 70 % of (100 - x) = 70 - 0.7x
we need to add 25 + 70-0.7x to get = 100 ml 60% i.e 60
now,
solve for x
0.7x =25+70-60
0.7x =35
x = 35/0.7
x= 50 % of the solution she needs to drain
Answer:
A. 38
Step-by-step explanation:
16% + 8% = 24%
24% of 50 = 12
50 - 12 = 38
Answer:
y=2 over 3x-4
Step-by-step explanation:
I just know pog
2500Y + 35,885 = 250,000
2500Y +35885 -35885= 250,000 - 35885
2500Y/2500 = 214115/2500
Y= 85.64
85 years is the answer
y=years
53.75/10.75= 5
Therefore, the oil last for 5 weeks.
Hope this helps!
