You can solve <span>9/x-4/y=8 for x or for y but NOT at the same time.
Solving for x: </span><span>9/x-4/y=8 Mult all 3 terms by xy to eliminate the fractions.
9(xy)/x - 4xy/y = 8xy => 9y - 4x = 8xy, or 9y = 4x + 8xy = 4x(1+2y)
then 9y = x [ 4(1+2y) ]
9y
therefore x = ------------
4(1+2y)
Solve for y using a similar approach.

You have to subtract 4 from 7 and then add 5 and 3 then add 8 and 2 then multiply 10 with 3 to get 30.
Answer:
D. 1200 mg
Step-by-step explanation:
In order to find the solution we need to understand that a dosage of 20 mg/kg means that 20 mg are administered to the patient for each kg of his/her weight.
So, if the patient weight is 60 kg then:
Total drug X = (20mg/Kg)*(60Kg)=1200mg.
In conclusion, 1200 mg will be administered to the patient, so the answer is D.
Positive: 1/2
Negative -0.25
Answer:
Answer is A: H 2
Step-by-step explanation:
Let's solve your inequality step-by-step.
5h−8h+12>18
Step 1: Simplify both sides of the inequality.
−3h+12>18
Step 2: Subtract 12 from both sides.
−3h+12−12>18−12
−3h>6
Step 3: Divide both sides by -3.
-3h/-3 > 6/-3
h<−2
