You can go through the set and test each one out:
x=0:
2(0)+3 ≥ 7? Or 3≥7? No
x=0.6:
2(0.6)+3≥7? 4.2≥7? No.
x=2:
2(2)+3≥7? 7≥7? Yes.
x=4:
2(4)+3≥7? 11≥7? Yes.
x=6:
2(6)+3≥7? 15≥7? Yes.
The set is {2, 4, 6}.
You can do
70 x 6000
and
6000 x 70
=420000
I Hope this will help. Im not 100% sure it is right :)
6- 3.5= 3 1/2
6-3= 3
3- 0.5= 2.5 so
6- 3 1/2 is 2 1/2 or 2.5
Another basic one
(1/2)^2*1/2*(1/2)^3=
(1/2)^6 =
1\2^6=1/64
if in decimal: 0.015 but i would prefer 1/64 if i was the teacher :)
