Answer:

3,493 digits

Step-by-step explanation:

Total pages of the book = 1,150

Page 1 - 9 = 9 digits

Page 10 - 99

= 2 * 90 pages

= 180 digits

Page 100 - 999

= 3 × 900 pages

= 2,700 digits

Page 1000 - 1,150

= 4 × 151 pages

= 604 digits

Total digits required in numbering 1,150 pages = 9 + 180 + 2,700 + 604

= 3,493 digits

Total digits required in numbering 1,150 pages = 3,493 digits

What is the value of x in the equation 6(x + 1) – 5x = 8 + 2(x - 1)?<br> OIT MT
Alexandra [31]

Answer:

x=0

Step-by-step explanation:

To solve, we need to get all the variables on one side of the equation, and all the numbers on the other

6(x + 1) – 5x = 8 + 2(x - 1)

First, distribute the 6 on the left

6*x+6*1 -5x=8 +2(x-1)

6x+6-5x=8+2(x=1)

Combine like terms on the left

(6x-5x)+6=8+2(x-1)

x+6=8+2(x-1)

Distribute the 2 on the right

x+6=8+2*x+2*-1

x+6=8+2x-2

Combine like terms on the right

x+6=2x+(8-2)

x+6=2x+6

Subtract x from both sides

6=x+6

Subtract 6 from both sides

x=0

Hope this helps! :)

Consuelo's living room is in the shape of a rectangle and has an area of 360 square feet. The width of the living room is 5/8 it
uranmaximum [27]
<h2>Therefore the length of the living room = 24 ft</h2>

Step-by-step explanation:

Given that , Consuelo's living room is in the shape of rectangle and has an area of 360 square feet and the width of the living room is \frac {5}{8}   its length

Let ,the length of the living room is = x ft

Then width =\frac {5}{8}x ft

Therefore the area of the living room =x \times \frac {5}{8}x ft^2

According to problem,

x\times \frac {5}{8}x = 360

⇔\frac{5}{8}x^2=360

⇔x^2 = \frac{360\times 8}{5}

⇔x^2 = 576

⇔x=\sqrt{576}

⇔x = 24

Therefore the length of the living room = 24 ft

Solving the linear equations variable on one side
Brums [2.3K]

The pick up fee is $2.50.

After each mile, $1.95 is added.

That is, after the first mile, we have;

\begin{gathered} \text{Fe}e=\text{ 2.50 + 1.95(1)} \\ \text{After the second mile, we have;} \\ Fee=\text{ 2.50+1.95(2)} \end{gathered}

Isaac total charge = $27.46;

Generally, let the number of miles driven by the taxi be x, then we have;

1.95x+2.50=27.46

Solving for the number of miles Isaac travelled, we have;

\begin{gathered} 1.95x=27.46-2.50 \\ 1.95x=24.96 \\ x=\frac{24.96}{1.95} \\ x=12.8\text{miles} \end{gathered}

CORRECT OPTION:

1.95x+2.50=27.46;\text{ Isaac traveled 12.8 miles.}
