180-45=x
135=x
= Let Martina's cousin's age be = n
= Let her age be = n+12
After four years,
Cousin's age = n+4
Her age = n+12+4=n+16
But according to the question her age = 3(n+4) = 3n+12
Thus,
3n+12=n+16
3n-n=16-12
2n=4
n=4/2
Thus ,
Her cousin's present age = n = 2
Her cousin's present age = n = 2Her present age = n+12 = 2+12=14
Answer:
1.5
Step-by-step explanation:
The mean is 2.5
1-2.5=1.5
5-2.5=2.5 This is the absolute distance from the mean
3-2.5=0.5
1-2.5=1.5
1.5+2.5+0.5+1.5=6
6/4=1.5
