Answer:
1/4 page per minute
Step-by-step explanation:
To find the unit rate, we need the amount of page she read in 1 minutes. To do this we divide the pages by the minutes. Let x equal the pages she reads per minutes.
5/20=x
we can simplify the fraction by divide both the numerator and denominator by 5
(5/5)/(20/5)=x
Do the division
1/4=x

The slope of the line is 1/2.
Add '4y' to both sides of the equation, then subtract '10' both sides.
then you get 4y = 2x - 10
divide the equation by 4
you get: y = 1/2 x - 2.5
the equation for a straight line is y = mx + c where m is the slope
Answer: 303 meters
Step-by-step explanation:
The Burji Khalifa is 830 meters in height and the Sears tower is 527 meters in height.
