Answer:
Option A.
Step-by-step explanation:
We need to find the 500th digit if we write all the whole numbers from 1 to 500 in a row.
Single digit numbers are : 1-9 = 9 number = 9 digits
Double digit numbers are : 10-99 = 90 number = 180 digits
Total digits form 1 to 99 = 9+180 = 189
Now,
It means we have write 311 more digits.
After 99 we have 3 digit number.
311 is not divisible by 3. The number immediate before 311 which is divisible by 3 is 309.
It means the required digit is 2nd digit of 104th number after 99.
104th number after 99 is 203 and second digit of 203 is 0.
Therefore, the correct option is A.
Firstly, you must find the product of 2 and x which is 2x. Add 8 and you get 2x+8.
Hello!
First, "the difference" of 2 numbers means you subtract these numbers.
Then, 4 cubed is written as follows:
4³
Subtract:
4³-25
[If necessary] Evaluate:
64-25
39
Hope everything is clear.

Answer:
<h3>
Any of them.</h3><h2>
a ∈ R</h2>
Step-by-step explanation:
-5x - 4y = 2a 4x - 5y = 2
-4y = 5x + 2a -5y = -4x + 2
y = (5x + 2a):(-4) y = (-4x + 2):(-5)
y = -⁵/₄x - ¹/₂a y = ⁴/₅x - ²/₅
m₁ = -⁵/₄, b₁ = -¹/₂a m₂=⁴/₅, b₂= -²/₅
-⁵/₄ ≠ ⁴/₅
Different slopes means that two lines have one point of intercept (no mater what the b's are). That means that the system of linear equations has exactly one solution for any value of a.
