Answer: 20%

Step by Step Explanation: 

Start by subtracting 519.29 from 649, you would get 129.8

Then take 129.8 and divide that by 649.

You get 0.2 which equals 20%

Tip: To find the percent of a fraction you divide the numerator by the denominator. For example, if you want to find the percent on a test, and you get a 8/10 you just divide 8 by 10. Which obviously equals 80.

The line represented by the equation y=-3/2x is translated up 3 units.

Answer:

(0, 3)

Step-by-step explanation:

In slope intercept form, the y-intercept is the "b" or, in an example:

y = mx + b

- m is the slope

- b is the y-intercept

In our first equation, the b is 0 (y=-3/2x, there is no +/- b, so it is 0). If we add positive 3 (up 3 units) then the y-intercept will be 3. This, in a point, is shown with (0, 3) because the y-intercept is where the line hits the y-axis when x is 0.

A skier is trying to decide whether or not to buy a season ski pass. a daily pass is $75. A season ski pass is $350. The skier w

pishuonlain [190]

Since the skier has to rent skis for 30 dollars per day with both passes, we can ignore it while solving the question.

A season pass is 350, while a daily pass is 75.

$\frac{350}{75} = \frac{25\times 14}{25\times 3} = \frac{14}{3} = 4 \frac{2}{3}$

So a seasonal pass is equivalent to having 4.6667 daily passes. And you can't buy 0.6667 of a pass.

So, if you went at least 5 days with a seasonal pass, then the seasonal pass would be less expensive than a daily pass.

Set up a system of equations.

6s+b=139.5
b=3s

Substitite for b
6s+3s=139.5
9s=139.5
s=15.5

Now multiply by 3 to get the blazer price
15.5*3= 46.5

Final answer: $46.50
