What value of x makes the equation true?<br> 1-3x = 1 - x

Natasha_Volkova [10]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{0}}}}}$

Step-by-step explanation:

$\sf{1 - 3x = 1 - x}$

Move x to left hand side and change it's sign

Similarly, move 1 to right hand side and change it's sign

$\dashrightarrow{ \sf{ - 3x + x = 1 - 1}}$

Collect like terms

$\dashrightarrow{ \sf{ - 2x = 0}}$

Divide both sides by -2

$\dashrightarrow{ \sf{ \frac{ - 2x}{ - 2} = \frac{ 0}{ - 2}}}$

Calculate

$\dashrightarrow{ \sf{ x = 0}}$

Hope I helped!

Best regards! :D

Kyoko is reading a book by her favorite author. She read the first 20 pages in One-half of an hour. Reading at the same pace, Ky

eduard

Answer:

It will take her 3 hours to read 120 pages.

Step-by-step explanation:

The number of pages read(y) after x hour can be modeled by a linear function in the following format:

$y = ax + b$

In which a is the number of pages read per hour and b is the initial number of pages read.

A straight line goes through (0, 0)

This means that when $x = 0, y = 0$

$y = ax + b$

$0 = a*0 + b$

$b = 0$

(0.5, 20)

When $x = 0.5, y = 20$

$y = ax$

$20 = 0.5a$

$a = \frac{20}{0.5}$

$a = 40$

The function in:

$y(x) = 40x$

According to the graph, which statement must be true?

It will take her 2 hours to read 60 pages.

$y(2) = 40*2 = 80$

Less than 2 hours for 60 pages, so this is false.

It will take her 3 hours to read 120 pages.

$y(3) = 40*3 = 120$

This statement is true.

It will take her 4 hours to read 180 pages.

$y(4) = 40*4 = 160$

More than 4 hours to read 180 pages. So false.

It will take her 5 hours to read 210 pages.

$y(5) = 40*5 = 200$

More than 5 hours to read 210 pages. So false.

(2×6)-7+9^2+45÷5<br> Order of operations

Alex777 [14]

Answer:

Step-by-step explanation:

Simplify the following:

2×6 - 7 + 9^2 + 45/5

The gcd of 45 and 5 is 5, so 45/5 = (5×9)/(5×1) = 5/5×9 = 9:

2×6 - 7 + 9^2 + 9

2×6 = 12:

12 - 7 + 9^2 + 9

9^2 = 81:

12 - 7 + 81 + 9
