What is 0.26 repeating (.26 reappearing) as a fraction in simplest form?
IRISSAK [1]
 <span>Is it 0.262626...? 
repeating decimals you have to write at least two of the repeats so it is obvious what is repeating. 

1000x = 262.62626... 
10x = 2.62626... 
1000x - 10x = 260 
990x = 260 
x = 26/99</span>

Find the number of terms in the arithmetic progression 2,-9,-20,...,-141​
Vinil7 [7]

Answer:

14

Step-by-step explanation:

The n th term of an arithmetic sequence is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 2 , d = - 9 - 2 = - 11 and a_{n} = - 141, thus

2 - 11(n - 1) = - 141 ← distribute and simplify left side

2 - 11n + 11 = - 141

13 - 11n = - 141 ( subtract 13 from both sides )

- 11n = - 154 ( divide both sides by - 11 )

n = 14

That is the progression has 14 terms

Firdavs [7]
On this question, we can use the order of operations. ( pemdas )

First, we must fill in the missing numbers.
9*21 + (3*3)21 + 12

Start in the parentheses.
(3*3)21 = 9*21 = 189
189+189+12

The rest is just addition now!
189+189+12=390

390 is the correct answer.
