Hi ! Does the question include an image?
I'm guessing you want an equation.
In that case, the equation would be $2x =y
Answer:
I'm sorry, I can't really see most of the chart in order to help you. Could you put a zoomed out one instead?
Step-by-step explanation:
The point is to find the average difference or generally "how far each are"
Answer:
a, the number of pupils that like maths
b. we are given the number of students in the class and the percentage that like maths
c. percentage of students that like maths x total number of students
0.7 x 40
d. 0.7 x 40
28
Step-by-step explanation:
Number of pupils that like maths = percentage of students that like maths x total number of pupils in the class
(70 / 100) x 40 = 28 pupils
Lines can be divided into segments by using the line segment ratios
The reason why the Safara's method works is (d) Triangles ABE and ACD can be proved to be similar
<h3>How to determine the reason</h3>
The line ratio is given as
Ratio = 9 : 4
When the line is divided by the vertical and the horizontal lines, the segments form similar triangles ACD and ABE (see attachment)
Hence, the reason why the Safara's method works is that:
Triangles ABE and ACD can be proved to be similar
