As the area of the circle is proporcional of R^2...
(200/40)^2=5^2=25 times greater
You can use a number line to understand the place values.
Are these simultaneous questions or like seperate ones?
Simultaneous:
4x -3(7x-4) = 12
4x - 21x + 12 = 12
-17x = 0
X = 0
Therefore y = -4
***
If it's a graph
x int: (3,0)
Y int: (0, -4)
Um idk if that's the answers you wanted but I hope it helped somehow??
The bigger i believe is 3/4
