Answer:
x=5
Step-by-step explanation:
4×3x=12x
4×-2=-8
(12×x)-8=52
So you balance it to make it:
12x=60
60÷12=5
I hope this helps and please give brainliest and thank me
Answer:
The graph for x-2y>=-12 needs to get y aloneso add 2y to both sides to getx >=-12 +2ythen add 12 to both sides of the in equalityx+12 >=2ynext divide each term by 2x/2 + 6 >= yy<= x/2 + 6so the graph connects (0,6) and (2,7) and shade below the solid line
Answer:
a. 24.9476 Kg.
b. The safe daily dosage range is between 2494760 units /day and 6236900 units/day
c. Yes
Step-by-step explanation:
a. Lets see the convertion from lb to Kg:
- 1 Lb= 0.453592
- 55 lb = 0.453592*55= 24.9476 kg
b. Minimum daily dosage is 100,000 units /kg
- For this kid: 100,000 * 24.9476= 2,494,760 units/ day
- in 6 dosis; 2494760/6= 415,793.33 units every 4 hours
Maximun daily dosage is 250,000 units /kg
- For this kid: 250,000 * 24.9476= 6,236,900 units/ day
- in 6 dosis; 6,236,900/6= 1,039,483.33 units every 4 hours
c: Yes, because 525.000 units every 4 hours is between the minimun and maximun dosaje for this kid
Begin by following the herd . . . call the two numbers 'x' and 'y' .
You said that xy=1 , so y = 1/x
You said that x + y = 10, so x + 1/x = 10
Multiply each side by 'x': x² + 1 = 10x
Subtract 10x from each side: x² - 10x + 1 = 0
Use the quadratic formula to solve this, and the two solutions
that you get for 'x' are also the two numbers 'x' and 'y' .
They are
<em>9.89898</em>
and
<em>0.10102</em>
(rounded)
