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:
C. 10 000
Step-by-step explanation:
If we called:
x = children who have been vacinated against rubella only
2x = children who have been vaccinated against mumps
y = children who have been vaccinated agains both
Children who have been vaccinated against mumps only = x - y
And we know that y = 2*(x-y)
=> 2y = 3x
y = 5000
There fore x = 7500
The number of children who have been vaccinated against rubella
= 2x - y = 2*7500 - 5000 = 15 000 - 5000 = 10 000
The equation in standard form would be,

All you have to do is move -2/7x to the other side.
Hope this helped
