Answer:
William weighs 111 pounds.
Step-by-step explanation:
N = x+6
W = x
T = x-3
x+6+x+x-3=336
3x + 3 = 336
3x = 336 - 3
x = 333/3
x = 111
Answer:

I don't know if u can see it, but there.
X=12
Y=15
Z=20
<span>the sum of the first and three times the second is 54.
x + 3y = 54
3y = 54 - x
y= 54 /3 - x / 3 = 18 -x /3
</span>xy = x (18 -x /3) = 18x - x^2 / 3 = - 1/3 x ^ 2 + 18 x
<span>
</span><span>since a<0, it is concave downward, and the vertex is the maximum value. That vertex occurs at x= - b /2a = (-18) / (-2/3) = 12
</span>
<span>The first number is x=12.
The second is y = </span><span>18 -x /3 = 18- 12/ 3 = 18 - 4 = 14 </span>
