Step-by-step explanation:
Given
5 daises to 2 roses
Required
Determine the relationship between them
The question shows a direct proportion between number of daises and roses.
i.e.

Where d = daises and r = roses
Convert the above expression to an equation

Make k the subject

When d = 5 and r = 2;


So, the first relationship between d and r can be gotten by substituting 2.5 for k in d = kr
So:

----------- (1)
Make r the subject in (1)
------------------------(2)
Hence, the relationships between d and r are:

Answer:
x = 25
Step-by-step explanation:
Assuming Angle A, B and C are angles in a triangle.
∠A + ∠B + ∠C = 180º
(2x - 20) + (120) + (x + 5) = 180
2x - 20 + 120 + x + 5 = 180
3x + 105 = 180
3x = 75
x = 25
