the midpoint of ab is m (3,-4). If the coordinates of A are (8,-5), what are the coordinates of B
Answers
Answer:
work is attached and shown
The coordinates of the midpoint will be (-2,-3).
What is coordinate geometry?A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
A midpoint is a point that lies on a line connecting two other locations and is in the middle of the line. Given that the midpoint of AB is M(3,-4) and the coordinates of A are (8, -5).
The midpoint will be calculated by using the formula below:-
( 8 + x ) / 2 = 3
( 8 + x ) = 6
x = -8 + 6 = -2
( -5 + y ) / 2 = -4
( -5 + y ) = -8
y = -8 + 5 = -3
Therefore, the coordinates of the midpoint will be (-2,-3).

Leah scored a total of 18 points in the basketball game, and she scored p points in the second half of the game. Write an expression to determine the number of points she scored in the first half of the game. Then, find the number of points she scored in the first half of the game if she scored 2 points in the second half of the game.
Answers
Answer: 16 points for the first half game
Step-by-step explanation:
1st half = ?
2nd half= p
Total = 18
The expressions to get the score of the 1st game is 18 -p
If she scored 2points in the second half game that means p=2
To get the 1st half of the game you should do 18-2=16

Ina school 3/7 of the student are girls if there are 240 boys, find the number of girls
Answers
3/7 = 240
7/7 x 240 = 240
240/ 3/7 = 560
there is 560 kids
560-240(all kids - girls)
there is 320 boys
The number of Girls in a school is 180.
Find the number of girls.
There are girls in a school = 3/7
Number of boys in a school = 240
Assume that there are x students in a school.
Number of Girls = 3/7 of All Students.
= 3/7 of x
= 3x/7
We know that,
Total Students = Number of Boys + Number of Girls.
240 + 3x/7 = x
240 = x - 3x/7
240 = (7x - 3x) /7 (Taking L.C.M.)
240 × 7 = 4x
x = 60 × 7
x = 420
Total number of Students in a school is 420.
Thus, Number of Girls = 3/7 × x
= 3/7 × 420
= 180
So, the number of Girls in a school is 180.

Answers
Answer:
The value of angle P is 119 degrees
Step-by-step explanation:
When two angles are supplementary, it means that they add up to be 180 degrees. For example, if we have two angles only on a straight line, then both angles are supplementary angles.
Now, the information we have from the question is that angle P is three less than twice the measure of Q.
What this mean is that if Q is x, then P is 2x-3
So let’s add both to equal 180 since they are supplementary;
x + 2x -3 = 180
3x -3 = 180
3x = 180 + 3
3x = 183
x = 183/3
x = 61
This is the value of Q;
The value of P which we are asked to look for is 2x -3 = 2(61) -3 = 122 -3 = 119 degrees
