A newspaper stand sold 1,000 copies of the city newspaper for $1,600 write and solve an equation to find the price of one copy

Vsevolod [243]

Answer: $\$1.6$

Step-by-step explanation:

Let be "x" the price in dollars of one copy of the city newspaper.

You need to analize the information provided in the exercise:

1. The total number of copies of the city newspaper sold in the newspaper stand is:

$Total\ copies=1,000$

2. The amount of money earned by selling 1,000 copies of the city newspaper is:

$Total\ earned=\$1,600$

Then, you can determine that the value of "x" can be found with:

$x=\frac{Total\ earned}{Total\ copies}$

3. Finally, substituting values, you get:

$x=\frac{\$1,600}{1,000}\\\\x=\$1.6$

The sum of two numbers are 62 and the difference is 18. Wjat are the numbers

ddd [48]

Let the two numbers be x and y, then

x + y = 62 . . . . . . . (1)
x - y = 18 . . . . . . . .(2)

subtracting (2) from (1), we have:

2y = 44
y = 22

From (2), x + 22 = 62
x = 62 - 22 = 40

therefore, the two numbers are 40 and 22.

1. Find the x-intercept of the line: 5x - y = 10

lakkis [162]

To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for and solve for y. x-intercept(s): (2,0) y-intercept(s): (0,−10)
