in a survey of community 60% people read daily newspaper & 50% people read weekly newspaper & 20% people don't read any type of news paper. If 1500 people read both type of news paper, how many people were surveyed.

4500

Step-by-step explanation:

60% Daily

50% Weekly

20% None    

130% total    →   30% both Daily and Weekly

30% of total people = 1500

 0.30x = 1500

÷0.30     ÷0.30

      x = 4500

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
