Answer:
42
Step-by-step explanation:
x+(x+13)=71
2x+13=71
2x=71-13
2x=58
x=29 (alvin)
71-29=42 (elga)

Step-by-step explanation:
Given that the number of pages ares: 1,724
As we know that:
- (from 1 - 9) there are 9 one-digit numbers
- (from 10- 99) there are 90 two-digit numbers
- (from 100 - 999) there are 900 three-digit numbers
- (from 1,000 - 1,724) there are 725 four-digit numbers
So the total are:

Probability = 1/4, or 25%
The probability of rolling an even number on a die: 1/2
(1, 2, 3, 4, 5, 6; 3 are even numbers, 3/6 = 1/2)
The probability of flipping heads: 1/2
(heads or tails)
1/2 x 1/2 = 1/4
Answer:
