Answer:
The four consecutive odd integers = 15, 17, 19, 21
Step-by-step explanation:
Four consecutive odd integers in Mathematics when x is an integer is given as:
x , x + 2 , x + 4, x + 6
Where:.
First integer = x
Second integer = x + 2
Third integer = x + 4
Fourth integer = x + 6
The sum of the first and fourth is 55 greater than the opposite of the third
Hence :
x + x + 6 = -(x + 4) + 55
x + x+6 = (-x - 4) + 55
2x + 6 = -x + 51
Collect like terms
2x + x = 51 - 6
3x = 45
x = 15
Therefore,
First integer = x = 15
Second integer = x + 2 = 15 + 2 = 17
Third integer = x + 4 = 15 + 4 = 19
Fourth integer = x + 6 = 15 + 6 = 21
The four consecutive odd integers = 15, 17, 19, 21
Answer.
It is Important to open the compass more than half the length so that the arcs made would meet.
Explanation.
When you want to construct a perpendicular line to a line segment, say line AB, the follow steps are taken;
1) Open your compass to a radius greater than half the line AB.
2) With A as your center make an arc on top and below line AB.
3) Using the same radius and with B as our center, make other arcs on top and below line AB to meet the first arcs on both sides of the line.
4) Join the two intersection of the two arcs to cut line AB at M.
In so doing the line AB is said to be bisected perpendicularly. If the compass was opened less than half line AB, then the arcs could not have meet.
