Answer:
the answer is 10x^2-30x+20
Step-by-step explanation:
you have to distribute the numbers and multiply then add the matching variables.
X equals to 518/3 which equals to 172.6
57-36=21 times (rolled less than 3)
36:21 →12:7
75%; so if we say there are 100 people in this city that means 60 of them live in houses and 40 of them live in apartments. Of the 60 living in houses 20% of them (12% of total population; 60 x .20) own their own business and those in apartments (40) 10% of them (4% of total pop.; 40 x .10) have their own business. In total 16 of the 100 people have businesses and 12 of those people live in houses so 12/16 equals .75. We multiply this by 100 to get the percent so there’s 75% that a person who owns a business in this city will also live in a house.
