Answer:
3
Step-by-step explanation:
4(x + 1) + 8 = 24
Subtract 8 from each side
4(x + 1) + 8-8 = 24-8
4(x + 1) = 16
Divide by 4
4(x+1)/4 = 16/4
x+1 = 4
Subtract 1
x+1-1 = 4-1
x=3
Answer:
900 - 60n ≥ 450
n ≤ 7.5
Answer: 7 weeks
Step-by-step explanation:
Let n = numberof weeks.
In n weeks, you withdraw 60n from the account.
After withdrawing $60 for n weeks, teh amount must be at least $450. At least $450 means greater than or equal to $450.
900 - 60n ≥ 450
-60n ≥ -450
n ≤ 7.5

Answer:
337.5 mg
Step-by-step explanation:
A licensed nurse practitioner is instructed to give a patient 2700 milligrams of an antibiotic over a period of 48 hours. If the antibiotic is to be given every 6 hours
Hence: the number of doses or times the antibiotic would be administered =
48 hours/6 hours = 8 doses(times)
The amount of antibiotic that should be given in each dose is:
48 hours = 2700 mg
6 hours = x mg
Cross Multiply
48x = 2700 mg × 6 hours
x = 2700mg × 6/48
x = 2700/8
x = 337.5 mg
