Hi!
To solve this inequality, we have to isolate x on one side. Whatever we do to the equation we have to do it on both sides.
1.30x + 5.20 ≤ 18.20
Subtract 5.20 from both sides.
1.30x + 5.20 - 5.20 ≤ 18.20 - 5.20
1.30x ≤ 13
Divide by 1.30 on both sides.
1.30x/1.30 ≤ 13/1.30
x ≤ 10

Hope this helps! :)
3. X= y-3
You subtract 3 to the other side to make X the subject of the formula.
8 is b because a circle is 360.
Lateral area = 2(6*5( + 2(6*3)
total area = lateral area + 2(5*3)
Volume = 6*5*3
