The midpoint of the coordinates (3, 15) and (20,8) is -
Nat2105 [25]

Answer:

The midpoint of the given coordinates is (\frac{23}{2},\frac{23}{2})\ or\ (11.5,11.5).

Step-by-step explanation:

We have given two coordinates (3,15) and (20,8).

Let we have given a line segment PQ whose P coordinate is (3,15) and Q coordinate is (20,8).

We have to find out the mid point M(x,y) of the line segment PQ.

Solution,

By the mid point formula of coordinates, which is;

(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})

On substituting the given values, we get;

M(x,y)=(\frac{3+20}{2}, \frac{15+8}{2})\\\\M(x,y)=(\frac{23}{2},\frac{23}{2})

We can also say that M(x,y)=(11.5,11.5)

Hence The midpoint of the given coordinates is (\frac{23}{2},\frac{23}{2})\ or\ (11.5,11.5).

Bongani and Jane are friends. Bongani takes Jane's maths test paper and will not tell her what her number of points is. He knows
Crazy boy [7]

Answer:

Jane has 6 points, and B has 8 points.

Step-by-step explanation:

If both of them in total have 14 points, and B has 2 more points than Jane, this means that:

B+2=14

So to find their individual number of points, you need to take 2 away from 14

14-2=12

Since these are being divided to two people, you have to divide 12 too

12/2 = 6

6 is Jane's number of points. And now to find B just add 2 points to it which is 8.

Jane=6 Bondani=8

6+8=14
