how many 4 digit numbers n have the property that the 3 digit number obtained by removing the leftmost digit is one ninth of n
Tom [10]

Answer:

  7

Step-by-step explanation:

We want to find the number 4-digit of positive integers n such that removing the thousands digit divides the number by 9.

__

Let the thousands digit be 'd'. Then we want to find the integer solutions to ...

  n -1000d = n/9

  n -n/9 = 1000d . . . . . . add 1000d -n/9

  8n = 9000d . . . . . . . . multiply by 9

  n = 1125d . . . . . . . . . divide by 8

The values of d that will give a suitable 4-digit value of n are 1 through 7.

When d=8, n is 9000. Removing the 9 gives 0, not 1000.

When d=9, n is 10125, not a 4-digit number.

There are 7 4-digit numbers such that removing the thousands digit gives 1/9 of the number.

Multiple choice! please show how u got the answer
mafiozo [28]

{ \qquad\qquad\huge\underline{{\sf Answer}}}

The only order pairs among the given options that represent a function is :

  • (9 , -3) , (9 , -1) , (9 , -1)

Because : To be a function, every element of domain (x) can have only one unique value y, and if we get more than two values of y for same x, it isn't a function at all.
