Answer:
(-4,-3)
Step-by-step explanation:
-3x+3y = 3
2x-y =-5
Divide the first equation by 3
-x+y =1
Add this to the second equation
-x+y=1
2x-y =-5
---------------
x = -4
Now we need to find y
-x+y =1
-(-4) +y = 1
4+y = 1
Subtract 4 from each side
4-4 +y = 1-4
y =-3
(-4,-3)
It loses its negative sign.
This is the concept of statistics. The correct answer is:
There are twice as many participants in the 0-19 age group than in the 60-79 age group. This is because:
Number of participants in the age group 0-19 is 40 participants
Number of participants in the age group 60-79 is 20 participants.
From the above we see that the age group 0-19 is double the number of age group 60-79 years old.
Therefore our answer is option C
Answer:
12 multiples are 12,24,36,48,60,72,84,96,108,120
Step-by-step explanation:

1) 12*1= 12
2) 12*2=24
3) 12*3=36
4) 12*4=48
5) 12*5=60
6) 12*6=72
7) 12*7=84
8) 12*8=96
9) 12*9=108
10) 12*10=120
