18 months
……33inches, weight 25.5 pounds
When
he was born = 9 months…20 inches, weight 8, 4 pounds
Every
9 months his height growth is 33-20 = 13 inches, his weight is 25.5-8.4=17.1 pounds
<span>Pounds. This means, for every 9 months, his growth is
13 inches and his weight is 17.1 pounds. For example we can determine his
growth in 3 years.</span>
<span>3
years = 36 months, 36= 9*4, his height will be 4*13 inches= 52 inches, his
weight will be 4*17.1 = 68.4 pounds </span>
Answer:

Step-by-step explanation:

F = 9/5C + 32
Subtract 32 to both sides:
F - 32 = 9/5C
Divide 9/5 to both sides or multiply by its reciprocal, 5/9:
5/9(F - 32) = C
Simplify:
C = 5/9F - 160/9
Answer:-1/2
Step-by-step explanation:
Answer:
The elements of S-block elements are 14, so therefore to create an inequality model we declare S to be the unknown variable.
therefore since we have 14 elements we use an inclusive class interval from 1-14. the model is given as
1≤S≥14
Step-by-step explanation:
you have to declare variables before for the unknowns.
you also declare the class interval to be inclusive class interval or exclusive class interval.
