The right answer is Option C : 5
Step-by-step explanation:
Let,
The numerator of fraction = x
The denominator of a fraction is 10 more than its numerator.
When 1/3 is added to this fraction,
the resulting fraction’s denominator is three times the denominator of the original fraction its numerator is 15 less than its denominator
Therefore, it becomes
Taking LCM on left side
Multiplying both sides by 3(x+10)
The numerator of original fraction is 5.
The right answer is Option C : 5

Answer:
Step-by-step explanation:
19. 18-4.62=13.38 to spend on the systems or 6.69 a piece
20. 45000+300m=60000
m=50
45000+300m>60000
He needs at least 50 machines to make the 60000.
Answer:
What is the GCF of 36 and 84?
Find the prime factorization of 36.
Find the prime factorization of 84. 84 = 2 × 2 × 3 × 7.
To find the GCF, multiply all the prime factors common to both numbers: Therefore, GCF = 2 × 2 × 3.
GCF = 12.
The common factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84. We can get all the factors using the prime factorization method.
Step-by-step explanation:
The condo costs $163,000, earns $2,986 per month, spends no more than 25% of her income, then if she pays $33,000 for the down payment, the remaining amount would be $130,000. Since 20% of the initial cost is only $32,600, she can adjust her down payment to 20.25% of the initial cost so that the annual payments would be less.
We have
and
so the equation is indeed exact. So we want to find a function 
such that
Integrating both sides of the first equation wrt 
gives
Differentiating both sides wrt 
gives
So we have
or
