So the larger number is x, and the smaller number is y
7y=x
3x=7+4y
(So plug in the 7y=x information into the second equation)
3(7y)=7+4y
21y=7+4y
17y=7
y=7/17
I could be very much wrong but maybe 45 cm3
Answer:
Common difference is 13 for this arithmetic sequence 29,42,55,68,...
Step-by-step explanation:
Given the arithmetic sequence 29,42,55,68,...
we have to find the common difference of the above sequence.
Common difference of arithmetic sequence is the difference between two successive terms. Therefore, to find common difference we take any pair of successive numbers, and subtract.
Common difference,
d=42-29=13
d=55-42=13
d=68-55=13
Hence, the difference between two successive terms is 3
∴ Common difference is 13
