A scientist had 3/5 liter of solution. He used 1/6 of the solution for an experiment. How much solution did the scientist use fo
r the experiment?
1 answer:
13/30, because you find the common denominator, 30.
From there, what you do is think, what times 5 is 30? (Talking about 3/5) 6! So you multiply 3 and 6, and get 18/30.
Next, do the same with 1/6, and you get 5/30.
Finally, subtract 5/30 from 18/30, and you get 13/30.
Hope this helps!

Answer:
a = x² + 3x - 40
Step-by-step explanation:
a = l * w
a = (x - 5)(x + 8)
a = x(x + 8) - 5(x + 8)
a = (x² + 8x) + (- 5x - 40)
a = x² + 3x - 40
Answer:
<u>4 minutes</u>
Step-by-step explanation:
40=1 min
40=2 min
40=3 min
40=<u>4</u> min
40x4 or 40+40+40+40 is <u>160</u>
