Answer: x = 2

Step-by-step explanation:

10 - 2(2x + 1) = 4(x - 2)

10 - 4x - 2 = 4x - 8 distributed -2 into 2x + 1 and 4 into x - 2

8 - 4x = 4x - 8 added like terms (10 - 2 = 8) on left side

8 = 8x - 8 added 4x to both sides

16 = 8x added 8 to both sides

2 = x divided 8 from both sides

Answer:

No solution

Step-by-step explanation:

Actually, you have only one equation here. We will solve it for x.

Performing the indicated multiplication, we obtain:

10-2(2x+1)=4(x-2) => 10 - 4x - 2 = 4x - 8, or 10 - 2 = -8. This can never be true, so this equation has no solution.

If it takes 1074 digits to number the pages of a book starting with page 1. how many pages are in the book? The book has a total

Charra [1.4K]

Answer:

394 pages

Step-by-step explanation:

1- digit numbers:

1 to 9, number of digits = 9

2- digit numbers:

10 to 99, number of digits = 2(99 - 9) = 180

3- digit numbers:

100 to 999, number of digits = 3(999 - 99) = 2700

This is more than we have, but we know the number of pages is 3-digit.

Let it be x, then we have:

9 + 180 + 3(x - 99) = 1074
3(x - 99) = 1074 - 189
3(x - 99) = 885
x - 99 = 885/3
x - 99 = 295
x = 295 + 99
x = 394
