Answer A is the only one that seems to make sense to me id choose A
I think that you assumed that:
2k - 1 = k + 2
However we can't do this, because a square has 4 sides whilst a triangle only has 3 sides.
This means that we can say
4(2k - 1) = 3(k + 2)
We multiply by 4 due to 4 sides of the square, and by 3 due to the 4 sides of the triangle.
Lets expand the brackets, and solve it:
4(2k - 1) = 3(k + 2)
8k -4 = 3k + 6
5k -4 = 6 ( subtract both sides by 3x to collect the x values)
5k = 10 (add both sides by 4 to get the x's alone)
k = 2 (divide both sides by 5 to get what just x is)
So k = 2 units
Answer:the usual dosage would be
54.55 milligrams.
Step-by-step explanation:
When Ibuprofen is given for fever to children 6 months of age up to 2 years, the usual dose is 5 milligrams (mg) per kilogram (kg) of body weight when the fever is under 102.5 degrees Fahrenheit. This means that the usual dose for a 18 month old child would be 5 milligrams (mg) per kilogram (kg) of body weight. Since the weight of the child is 24 pounds, we would covert 24 pounds to kilogram.
2.2 pounds = 1 kg
24 pounds = 24/2.2 = 10.91 kg
Therefore, the dosage would be
5 × 10.91 = 54.55 milligrams
Answer:
x-5
Step-by-step explanation:
For this case we have the following expression:

Let's evaluate the expression for some values of x.
