The sum of two consecutive numbers is n+1. What are the numbers?

1 answer:

5 0

Let, consecutive number is (n-1) & n
Then: n-1+n = n+1
2n-1 = n+1
2n-n = 1+1
n = 2
& (n-1) = 2-1 = 1

So, numbers are 1 & 2

3) Prove that there is ann ∈ N such that 0.001 ∉ (0,1/n). (Hint: findsuch an n.)

Greeley [361]

Answer:

10000

Step-by-step explanation:

0.001 = 1/1000

so, we take an n bigger than 1000, let's say 10000, then 1/1000 > 1/10000 and 1/1000 ∉ (0, 1/10000).

2x-1/4(12x+4)=3 2x-1/4 (12x+4)=3

eduard

2x-1/4(12x+4)=3
⇒ 2x -1/4*(12x) -1/4*4= 3 (distributive property)
⇒ 2x -3x -1= 3
⇒ -x= 3+1
⇒ -x= 4
⇒ x= -4

Final answer: x=-4~
