Answer:
2n
Step-by-step explanation:
To find the 1st term, put n = 1 into the formula, to find the 4th term, replace the n's by 4's: 4th term = 2 × 4 = 8.
Step-by-step explanation:
Given,
x = y - 3
Also,
6(y - 3) = 3y + 6
6y - 18 = 3y + 6
6y - 3y = 6 + 18
3y = 24
y = 24/3
y = 8
x = 8 - 3
x = 5
Therefore, the first number is 5 and the second number is 8.
The answer is:
(-28/81)/(-2/3) = -84/(-162) = 42/81
Work
Think of this simple question:
Two number when multiplied together give 15. If one number is 5, then the other is (15/5)=3.
When we add rational numbers we simply add or subtract the fraction or part of a whole so in this particular equation we would subtract 1 from 4 because adding a negative means the same thing. We then subtract 2/3 from 3 and get 2 1/3 Comment below if more details are required
