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:
B. (-9/2, -11/2)
Step-by-step explanation:
-12+3 / 2 = -9/2
-3+-8 / 2 = -11/2
A = 1/2 bh
A = 1/2 (9)(5)
A = 45/2
A = 22.5
answer
22.5 cm^2
Base number, like in the equation 4², 4 is the base number
