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

Answer:
5 Hours
Step-by-step explanation:
340 = 215 + 25x
DO INVERSE OPERATIONS ~ MINUS BOTH SIDES OF THE = SIGN
340 - 215 = 125
215 - 215 = 0
125 = 25x
DIVIDE BOTH SIDE NOW
125 / 25 = 5
25x / 25 = 1 = x
