Explain what is happening at this step in the solving equation process.

aleksklad [387]

Answer:

1. After solving we get value of x: $\mathbf{x=\frac{6}{11} }$

2. After solving we get value of x: $\mathbf{x=\frac{6}{11} }$

Step-by-step explanation:

We need to Solve the equations.

1. $10 - 6 x = 4 + 5 x$

Step 1: Subtract 5x on both sides

$10 - 6 x-5x = 4 + 5 x-5x\\10-11x=4$

Step 2: Subtract 10 on both sides

$10-11x-10=4-10\\-11x=-6$

Step 3: Divide both sides by -11

$\frac{-11x}{-11}=\frac{-6}{-11}\\x=\frac{6}{11}$

So, after solving we get value of x: $\mathbf{x=\frac{6}{11} }$

2. $7-6x=1+5x$

Step 1: Subtract 5x on both sides

$7 - 6 x-5x = 1 + 5 x-5x\\7-11x=1$

Step 2: Subtract 7 on both sides

$7-11x-7=1-7\\-11x=-6$

Step 3: Divide both sides by -11

$\frac{-11x}{-11}=\frac{-6}{-11}\\x=\frac{6}{11}$

So, after solving we get value of x: $\mathbf{x=\frac{6}{11} }$

What is the total number of digits required in numbering the pages of a book, which has 1,724 pages?

Alex Ar [27]

Answer:

5789 digits

Step-by-step explanation:

Given that the number of pages ares: 1,724

As we know that:

(from 1 - 9) there are 9 one-digit numbers
(from 10- 99) there are 90 two-digit numbers
(from 100 - 999) there are 900 three-digit numbers
(from 1,000 - 1,724) there are 725 four-digit numbers

So the total are:

$= 9(1)+90(2)+900(3)+725(4)\\\\= 9+180+2,700+2,900\\\\= 5,789\ digits$
