Answer:
Step-by-step explanation:
4.5 is equal to nine halves because if you divide 9 you get 4.5
We know that 20% of the first type of juice is pure fruit juice and 45% of second type of juice is pure fruit juice.
Now we have to make 30 pints of a mixture that is 35% pure.
Let x be the number of pints of first type of juice and y be the number of pints of second type of juice.
So,
(Equation 1)
Since, 20% of x + 45% of y = 35.3% of 30
(Equation 2)
Solving equations 1 and 2,
we get y=18 and x=12.
So, 12 pints of first type of juice and 18 pints of second type of juice are used.
X=9 -12 divided by -4 is -3, so you get -3x=-27. When you divide -27 by -3 you get positive 9. Thus making X=9
Answer:
4
Step-by-step explanation:
The easiest way to solve this is just to put it in your calculator.
But if you want to go deeper, then ln(x)^4 = 4*ln(x)
Since x in this case = e then ln (e)^1 = 1.
ln(e)^4 = 4*ln(e) = 4
Answer:
m = 17h
Step-by-step explanation:
85/5 = 17 (she makes $17 per hour)
Therefore:
m = 17h
