Answer:
Step-by-step explanation:
Given sequence: 
Therefore,
General form of an arithmetic sequence: 
(where a is the first term and d is the common difference)
To find the common difference, subtract a term from the next term:
Therefore,
To find the 6th term, input n = 6 into the equation:
She added the numerators
instead of multiplying them
you should also simplify the final answer
the correct answer would be -3 1/8 or -25/8 as an improper fraction.
6x=18 (2x+5) x=6x+15. x-15=6x 5x=15 x=3
Answer:
The number of feet she will travel back is 1 or 7 feet
Step-by-step explanation:
Here, we need to solve the quadratic equation
That will be as follows;
0 = x^2 -8x + 7
x^2-x-7x+ 7 = 0
x(x-1)-7(x-1) = 0
(x-1)(x-7) = 0
x = 1 or 7
The number of feet she will travel before coming back to the surface of the water is 1 or 7 feet
Answer: 60.
Step-by-step explanation: After you divide you get 60.037037. And since were rounding its 60.
