2*2*5 = 20
90
10
In 2573 it is worth 500 and in 6459 it is worth 50, so 500 is ten times 50.
5a = a + a + a + a + a
If you mean: 2x+5+3x = 25 then the value of x works out as 4
If: 2x+5 = 45 then the value of x works out as 20
41
2 x 2 x 2 x 2 x 2 = 32
5 x 5 x 2 x 2 = 100
One million times greater.
I belivie it is 400.
Applying BODMAS, 32 - (15 x 2) + 3 = 5
