Answer:
r = 2.5
Step-by-step explanation:
The equation given says y = r * x
So, the y value would be an unknown times the given x value.
To solve for r, all you have to do is divide.
25 ÷ 10 = 2.5
12.5 ÷ 5 = 2.5
10 ÷ 4 = 2.5
2.5 is the constant of proportionality.
Given :




Let's solve by using midpoint formula :

Answer:
Step-by-step explanation:
As the equation is given in the question as follows.
2.5(6x-4)=10+4(1.5+0.5x)
open the bracket
2.5 × 6x - 2.5 × 4 = 10 + 4 × 1.5 + 4 ×0.5x
15x - 10 = 10 + 6 + 2x
15x - 2x = 16 + 10
13x = 26
x = 2
