What is the total number of digits required in numbering the pages of a book, which has 105 pages?

207

Step-by-step explanation:

So list out the numbers from digits.

1 digit numbers: 9

2 digit numbers: 90

3 digit numbers: 6

9 * 1 = 9

90 * 2 = 180

3 * 6 = 18

9 + 18 + 180 = 207

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the answer.
