Add the two equations and use the elimination method. The x term will "cancel out" to be able to solve for the y term.
STEP 1
−12x−5y=40
12x−11y=88
x terms "cancels out"; add y terms
-16y= 128
divide both sides by -16
y= -8
STEP 2
substitute y value into either original equation
12x−11y=88
12x - 11(-8)= 88
12x + 88= 88
subtract 88 from both sides
12x= 0
divide both sides by 12; 0 divided by any number is 0
x= 0
ANSWER: x= 0; y= -8

Answer:
6 ways
Step-by-step explanation:
Given
Number of Sports: 3
Required
Determine the total number of schedules
Since, there are 3 sports and the schedule is in no particular order.
The number of schedules is calculated as thus:

Where:

So, we have:


Answer:
Correct choice is C. 2 mL.
Step-by-step explanation:
Given that Ampicillin 250 mg IM every 12 hours is ordered. After reconstitution, there's 125 mg/mL. Now we need to find about how many mL would you give.
Let number of ml needed = x.
Since ratio of mg per mL will be fixed so we get equation:





Hence correct choice is C. 2 mL.
(856/12) - (907/16) = 14.645833
So the difference is, 14.645833.
