Given:
I have walked 20% of the way to school.
I have 1200 metres more to walk than when I have 20% of the walk remaining.
To find:
The distance from home to school.
Solution:
Let x be the distance from home to school.
I have already walked 20% of the way to school and i have 1200 metres more to walk than when I have 20% of the walk remaining.
It means 1200 is of the total distance from home to school.
Therefore, the distance from home to school is 2000 metres.
10% of 55 is 5.5
You could divide 55 by 10 to get 5.5 or multiply 55 by the decimal representation of 10% which is .1
.1 x 55 = 5.5
55 / 10 = 5.5
Answer:
<h2>BD = DC</h2>
Step-by-step explanation:
A perpendicular bisector is a line segment that goes form a vertex to its opposite side. The important characteristic is that a perpendicular bisector intersects the opposide at the mid point and with a right angle, that's why is called perpendicular and bisector.
So, Andrew can conclude that side BC is divide equally, that is, BD = DC.
Therefore, the right answer is the second choice.

➷ Split it into different sections and calculate the area:
4 x 2 = 8
3 x 2 = 5
4 x 2 = 8
Add these together:
8 + 8 + 5 = 21 (whatever unit it is)^2

Answer:
(A)Step 1; it should be m∠m + m∠n + m∠o = 180 degrees (sum of angles in a triangle)
Step-by-step explanation:
- In the triangle, the exterior angle = p
- The adjacent interior angle =o
- The two opposite angles are marked m and n
The steps followed by the student are:
Step 1: m∠m + m∠n + m∠p = 180 degrees (sum of angles of a triangle)
Step 2: m∠p + m∠o = 180 degrees (adjacent supplementary angles)
Step 3: Therefore, m∠m + m∠n + m∠o = m∠o + m∠p
Step 4: So, m∠m + m∠n = m∠p
We observe that the student made a mistake in Step 1, it should be m∠m + m∠n + m∠o = 180 degrees (sum of angles in a triangle).
p is outside the triangle, therefore it cannot form one of the angles in the triangle.
