Answer:

Step-by-step explanation:

so we have Louis who weighs 140 lbs

then we have x boxes that weigh 10 kg....or (2.2 * 10) = 22 lbs

and we have (20 - x) boxes that weigh 30 kg or (2.2 * 30) = 66 lbs

140 + 22x + 66(20 - x) =

140 + 22x + 1320 - 66x =

1460 - 44x <====

Solve for x. 6x-10≤8 or 1/3 x+6>12

Feliz [49]

The solution is

$x\le 3 \:or \:x>18$

$EXPLANATION$

$6x-10\le 8\: or \frac{1}{3}x+6>12$

We group like terms, to obtain;

$6x\le 8+10\: or \frac{1}{3}x>12-6$

Simplify to get,

$6x\le 18\: or \frac{1}{3}x>6$

We further simplify to get;

$x\le 3\: or x>18$

This can also be rewritten as;

$x\le 3, x>18$

$(-\infty 3] \cup (18,+ \infty)$

This can be represented on the number line as shown in the diagram.
