Answer:
1 1/2
Step-by-step explanation:
2 2/3 - 1 1/6 = ?
The LCD here is 6. Convert 2 2/3 so that the denominator is 6:
2 2/3 = 2 4/6
Then subtract 1 1/6 from 2 4/6: We get 1 3/6, or 1 1/2
Answer:
A) Yes, 7
Step-by-step explanation:
The given sequence An = {13, 20, 27, 34, ...}
Here the first term Ao = 13 and difference between the successive terms is (d) = 7
That is d = 20 - 13
d = 7
It is an arithmetic sequence. d = 7
Answer: Yes, it is arithmetic sequence and common difference (d) = 7
Thank you.
Maria = x
Tom = y
Use substitution
x+y=30
2y=x
2y+y=30
3y=30
y=10
Tom is 10 years old.
x+y=30
x+10=30
x=20
Maria is 20 years old.
