We can find the midpoint by using the two given coordinates and finding the average between them.

We will find the average between the x coordinates and the y coordinates.

We are given these two coordinates of line segment QR: (-3, 14) and (7, 5). Find the midpoint by finding the average (or mean) between the x coordinates (-3 and 7), and the y coordinates (14 and 5).

Find the average by adding up the two coordinates then dividing the answer you get by 2 (because you added two numbers).

x coordinates average: -3 + 7 = 4, 4/2 = 2; their average is 2

y coordinates average: 14 + 5 = 19, 19/2 = 9.5; their average is 9.5 (or 19/2)

Take the two averages and put them together so your answer is: the coordinate of the midpoint of line segment QR is (2, 19/2).

Answer:

31/3 or 31 over 3

Step-by-step explanation:

If you do the whole number (10) times the denominator (bottom number of the fraction,in this case 3) the add the numerator (top number of the fraction,in this case 1) you will get your improper fraction.

Answer:

The value of the house after adding the garage is $135,700.

Step-by-step explanation:

Given,

value of house before adding garage = $118,200.00

we need to find the value of house after adding two car garage.

Solution,

Since after adding two car garage the value of the house increased by 15%.

So firstly we will find out the 15% of the value of the house after adding garage.

So we can say that;

15% of the value of the house after adding garage is equal to 15 divided by 100 the multiplied with the value of the house before adding garage.

15% of the value of the house after adding garage = $\frac{15}{100}\times118,000=\$17,700$

Now, The value of the house after adding garage is equal to the sum of value of house before adding garage and 15% of value of house before adding garage.

We can frame it in equation form as;

The value of the house after adding garage = $\$118,000+\$17,000=\$135,700$
