So,
We just have to substitute the appropriate words for the operations and grouping symbols.
A. Twenty times the quantity of the difference between y and 3.
B. The sum of the quotient of x and 9, and 5
Answer:
h=-3
Step-by-step explanation:
Combine like terms ( -2.5h )
1.8=-2.5h-5.7
Add 5.7 to 1.8 ( 7.5 )
Bring down -2.5h
the divide ( 7.5/-2.5 )
h= -3
Regarding the points on the given line, it is found that:
a) The midpoint is: (3,4.5).
b) The coordinates of C are: C(4,5).
c) The coordinates of the other end of the line are: (4,3).
<h3>Midpoint</h3>
The midpoint between two points is given by the mean of the coordinates of these points.
In this problem, the coordinates of points A and B are given as follows:
A(0,3) and B(6,6).
Hence the coordinates of the midpoint are given as follows:
- x-coordinate: (0 + 6)/2 = 3.
- y-coordinate: (3 + 6)/2 = 4.5.
As for point C, we have that C is closer to B then A, hence:
- The x-coordinate is greater than 3.
- The y-coordinate is greater than 4.5.
The coordinates are integers, hence it is given as follows:
C(4,5).
As for line AB, it is found that:
- The other line is parallel, hence the slope is also of 0.5. (change in y divided by change in x is of 0.5).
- For the x-coordinate, on line AB, they change by 6, hence in the new line they increase by 2/3 x 6 = 4.
- For the y-coordinate, on line AB, they change by 3, hence in the new line they increase by 2/3 x 3 = 3.
Thus the other endpoint is:
(4,3).

Answer:
let the two numbers be x and y
x+y=45(equation 1)
x-y=5(equation 2)
from equation (1) y=45-x(equation 3)
substitute 45-x for y in equation 2
x-(45-x)=5
x-45+x=5
x+x-45=5
2x-45=5
2x=45+5
2x=50
x=50/2
x=25
