Answer:
7÷72
Step-by-step explanation:
First take lcm of the denominator
Then solve
(13*4-5*9)/73
52-45/72
7/72
24x-16 is 8*(3x-2). Therefore, there are 8 rows of trees.
Answer:
25²×3is the equivalent answer
Answer:
69
Step-by-step explanation:
Hey there! To find the 20th term of arithmetic sequence, we can do by using general terms.
<u>General Term</u> - Arithmetic
where a_n is nth term, a_1 is the first term and d is our common difference.
We know the first term which is 12 and we want to find the 20th term which is our desired term.
Hence, the equation is
However, we don’t know the value of d yet which is common difference. To find the common difference, we can do by subtracting next term with previous term.
15-12 = 3
18-15 = 3
21-18 = 3
If we keep doing it, we’ll always get 3. Therefore, 3 is our common difference.
Thus, the 20th term is 69.
