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:
x = 15
Step-by-step explanation:
We assume you want to find the value of x.
Know (or prove) that in this geometry, all of the right triangles are similar. That means the ratios of corresponding sides are proportional.
short side / hypotenuse = 9/x = x/25
x^2 = (9)(25) . . . . . . . . . . multiply by 25x ("cross multiply")
x = √((9)(25)) = (3)(5) . . . take the square root
x = 15

Answer:
A = 5x + 3y
B = 8x + 5y
C = 15x + 11y
Step-by-step explanation:
B = 6x + 2y + 2x + 3y
= 6x + 2x + 2y + 3y
= 8x + 5y
C = 8x + 5y + 7x + 6y
= 8x + 7x + 5y + 6y
= 15x + 11y
A = 7x + 6y - 2x - 3y
= 7x - 2x + 6y - 3y
= 5x + 3y
