80\((2 power3+2)x4)+1
(2power3+2=10 x 4 =40
80 divided by 40+1
answer=3
<span>6cm - 900000cm multiplica cruzado ⇒ 6x = 900000 ⇒ x = 150000cm
1cm - x
1cm - 150000cm multiplica cruzado -> d = 600000cm = 6km 4cm - d

For this, you have to calculate the Unit value,
Unit value of 1rst one, 4.99/6 = 0.83
Unit value of 2nd one, 7.99/10 = 0.79
As, 2nd one is cheaper, so it is better :))
So 9x<18 can be factored out into
9(x)<9(2)
you can divide both sides by 9
x<2
so the solution is any number more than 2, but not 2
