X=y+2
x=3y
2x=4y+2
4y+2=2(y+2)
4y+2=2y+4
2y+2=4
2y=2
y=1
x=3
1+3=4
Their sum is 4
Hope this helps :)
a. If we subtract 75 from 550 twice, we get 400, which is the third member to join. Subtract 75 from 400, we get $325, the fourth member to join.
b. It is not possible that a member would join for free if it was a large family. 75 does not fit into 550 evenly. You can prove this by solving the expression 550÷75.
c. The lowest amount that a member would pay to join is $25.00. It would be the 7th member.
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
