Question

Solve.
0.4x + 8 <= 1.2x - 5

Answer 1

Bring all the x's to one side by substrating 0.4x from 1.2x

0.4x + 8 <= 1.2x - 5
+ 8 <= 1.2x - 0.4 - 5
Combine like Terms (1.2x - 0.4x)
8 <= 0.8x - 5
Bring 5 to the other side by adding it:
8 + 5 <= 0.8x
Add 8 + 5 =
13 <= 0.8x
Divide by 0.8
13/0.8 < = x
16.25 < = x

Answer 2

0.4x +8 = 1.2x - 5
transpose 1.2x to left hand side
0.4x-1.2x + 8 = -5
transpose 8 to right hand side
0.4x-1.2x = -5-8
-0.8x = -13
x = -13/(-0.8)
x = 13/8 * 10
x = 16.25
Hope u got it

Answer 3

Kush the inequality has to be x is greater than or equal to 16.25..
Equals alone would be incorrect but good try Kush =)

Answer 4

The answer I got isn't correct so I am doing something wrong.
