Noah is thinking of two fractions that have a sum of 35. Each fraction has a numerator of 1.
Zinaida [17]

The denominators of the fractions are 2 and 10.

<h3>The fractions with numerators of 1 that have sum of 3 / 5  is calculated below</h3>

The sum of the fractions are 3 / 5. Each of the fractions have a numerator of 1. Therefore, let the denominators be x and y

  • 1 / x + 1 / y = 3 / 5

Therefore,

1 / x  + 1 / y = 3 / 5

y + x / xy = 3 / 5

cross multiply

5y + 5x = 3xy

Using hit and trial method,

5(2) + 5(10) = 3(10)(2)

10 + 50 = 60

60 = 60

The values are same.

Therefore, the denominators are 2 and 10.

Chris needs to make a 500 L of a 35% acidic solution. He has only two of the acidic solutions available, a 25% solution and a 50
DaniilM [7]
Yes, very fun, not


ok
one way is table or

solutions amount x and y
x+y=500
x=25%
y=50%
0.25x+0.5y=0.35(500)

we have
x+y=500
0.25x+0.5y=0.35(500)
0.25x+0.5y=175
solve

multiply second equation by 100
25x+50y=17500
divide everybody by 25
x+2y=700

now we have
x+y=500
x+2y=700

multiply first equation by -1 and add to second equaiton

-x-y=-500
<u>x+2y=700 +</u>
0x+1y=200

y=200
sub
x+y=500
x+200=500
x=300


300L of the 25% and 200L of the 50%
