Answer:
9 ml
Step-by-step explanation:
The Pediatrician prescribes 5 milliliters of cough syrup for every 25 lb of child weight.
Now, the weight of Jocelyn is 45 lb.
If the rate of prescribing the cough syrup in ml per weight of patients remains constant,
Then we can use the unitary method to get the amount of cough syrup prescribed by the Pediatrician for Jocelyn, and that will be
ml. (Answer)
Answer:
y = 40 x = 80
Step-by-step explanation:
520 = 3.25x + 6.5y and x+y=120
x+y=120
x = 120-y
520 = 3.25(120-y)+6.5y
520 = 390-3.25y+6.5y
520 = 390+3.25y
130=3.25y
40 = y
x = 120-y
x = 120-(40)
x = 80

The rational root theorem states that the rational roots of a polynomial can only be in the form p/q, where p divides the constant term, and q divides the leading term.
In your case, both the leading term 5 and the constant term 11 are primes, so their only divisors are 1 and themselves.
So, the only feasible solutions are
For the record, in this case, none of the feasible solutions are actually a root of the polynomial.
