Answer:

$32.80

Step-by-step explanation:

Let f be the cost of a file, then a storybook costs 3f ( 3 times as much )

Then the difference in cost is

3f - f = 16.40, that is

2f = 16.40 ( divide both sides by 2 )

f = 8.20

The cost of a file is $8.20 and the cost of a storybook is 3 × $8.20 = $24.60

The total cost of the 2 items = $8.20 + $24.60 = $32.80

Ron gets $5 on the first day at work, the square of that amount on the second day, and three times the amount of the second day
Ket [755]

Answer:

5 + 25 + 75 = 105 dollars

Step-by-step explanation:

The easiest way is to just take this day by day.

day 1: 5 dollars

day 2: day1^2 = 5^2 = 25

day 3: 3 * day2 = 3 * 25 = 75

Then sum them: 5 + 25 + 75

Complete the following sentence. The slope of the graph of y = 5 x is ___
Y_Kistochka [10]

Answer:

We conclude that the slope of the graph of y = 5 x is 5.

Step-by-step explanation:

We know the slope-intercept form of the line equation

y = mx+b

where

  • m is the slope
  • b is the y-intercept

Given the line

y = 5x

comparing with the slope-intercept form of the line equation

The slope of the line = m = 5

Therefore, we conclude that the slope of the graph of y = 5 x is 5.
