You wake up with a fever! all you can find at the store is aspirin, and the bottle says to take 162 mg. the bottle also says each tablet has 81 mg in each tablet. how many tablets should you take? 5. when you don't seem to get any better, you eventually end up in the hospital. the doctor orders 120 mg of medicine to be given twice a day. the nurse comes in with 6 tablets and tells you that there are 30 mg in each tablet. is this the correct dosage? if not, how many tablets should you get? 6.

You should take 2 tablets of Aspirin.

Six tablets is not the correct dosage.

You should get 4 tablets.

Step-by-step explanation:

You wake up with a fever! All you can find at the store is Aspirin, and the bottle says to take 162 mg. The bottle also says each tablet has 81 mg in each tablet. How many tablets should you take?

This can be solved by this following rule of three.

1 tablet - 81mg

x tablets - 162mg

You should take 2 tablets of Aspirin.

The doctor orders 120 mg of medicine to be given twice a day. The nurse comes in with 6 tablets and tells you that there are 30 mg in each tablet. Is this the correct dosage?

We need to see how many mg are in 6 tablets. If there are 120mg in 6 tablets, this is the correct dosage. We verify this by the following rule of three:

1 tablet - 30mg

6 tablets - x mg

mg.

In 6 tablets, there are 180mg. So, it is not the correct dosage.

If not, how many tablets should you get?

Knowing that each tablet has 30mg, in how many tablets are there 120mg?

1 tablet - 30 mg

x tablets - 120 mg

You should get 4 tablets.

make sure you have version 2.50

try looking in the very back of the book : )

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
