Set up the equation it's equavilvent to the same side of the other one
x-1=6
+1=+1
x=7
The steps 5 and 6 in the construction of a new line segment ensures the lengths are equal.
A line segment in geometry has two different points on it that define its boundaries. Alternatively, we may define a line segment as a section of a line that joins two points.
Below are the steps for copying a line segment:
- 1. Let's begin with a line segment we need to copy, AB.
- 2. we take a point C at this stage. That will be one endpoint of the new line section, either below or above AB.
- 3. Now we place the the compass pointer on the point A of line segment AB.
- 4. We spread the compass out until point B, making sure that its breadth corresponds to the length of AB.
- 5. We place the compass tip on the point C created in step 2 without adjusting the compass's width.
- 6. We now draw a rough arc without adjusting the compass's settings. we add a point D oh the arc . The new line segment will be formed by this.
- 7. From C, draw a line to D;CD thus formed is equal to AB.
Hence steps 5 and 6 are the steps in the construction of a new line segment which ensures the lengths are equal.

For question 6 the answer is 100 because a quarter of a circle is 90 degrees
Answer:
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Parallel lines have the same gradient. Hence the gradient of line r is 
.
Susbt. m=,
To find c, substitute a coordinate.
When x=3, y= -9,
-9= 1 +c
c= -9-1
c= -10
Thus the equation of line r is .
Answer:
4(X+2Y)
Step-by-step explanation:
Rearrange the equation:
X+3X+Y+7Y
Combine like terms (so add coefficients of like variables):
4X+8Y
Factor if necessary:
4(X+2Y)
