Answer:

-\frac{41}{65}

Step-by-step explanation:

In order to find the answer to this question remember to use KCC (Keep, Change, Change) and find the least common denominator. (LCD)

-\frac{3}{13}-\frac{2}{5}

Use KCC

-\frac{3}{13} +-\frac{2}{5}

Now add

LCD=65

\frac{-3\times5}{13\times5} -\frac{2\times13}{5\times13}

=\frac{-15-26}{65}

=-\frac{41}{65}

Hope this helps.

Does the point (1, –9) satisfy the equation y = 3x − 6?
Tju [1.3M]

Answer:

No.

Step-by-step explanation:

Well, is the points (1, -9) does satisfy the equation y = 3x - 6. Then, substituting the values of x, and, y, into the equation y = 3x - 6,  we should get a true equation.

y = 3x - 6

-9 = 3 * 1 - 6

-9 = 3 - 6

-9 = -3.

So, the points (1, -9) does not satisfy the equation y = 3x - 6.

In a city, 60% of the residents live in houses and 40% of the residents live in apartments. Of the people who live in houses, 20
Step2247 [10]
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.
