If you follow the order of pemdas the answer would be (-24)
Pythagora: 20^2=(4x)^2+(3x^2)
400=16x^2+9x^2
x^2=400/25
x^2=16
x=4
<u>Answer:</u>
Consistent and dependent
<u>Step-by-step explanation:</u>
We are given the following equation:
1. 
2. 
3. 
For equation 1 and 3, if we take out the common factor (3 and 4 respectively) out of it then we are left with
which is the same as the equation number 2.
There is at least one set of the values for the unknowns that satisfies every equation in the system and since there is one solution for each of these equations, this system of equations is consistent and dependent.
Step-by-step explanation:
Dosage per kg per day = 8mg
2 doses = 4mg
If a person weighs 82 pounds =? mg
1kg = 2.205 pounds
So 82 ÷ 2.205 = 37. 195 kg
So he should receive 37. 195 mg every 12 hours
