Answer:

$3w+45=557$

Step-by-step explanation:

Let the weight of box Y be w kg.

Box X weighs 33 kg more than Box Y, then the weight of box X is

$w+33$ kg.

Box Z weighs 12 kg more than Box Y, then the weight of box Z is

$w+12$ kg.

The total weight of all boxes is

$w+(w+33)+(w+12)=w+w+33+w+12=3w+45$ kg

Jane measured the total weight of all the boxes and it was found to be 557 kg, therefore,

$3w+45=557$

or

$3w=512$

HELP WILL MARK AS BRAINLIST

Hi!

Given:

$\frac{x}{-1} > -6$

Multiply both sides by $-1$

$x$

<em>Notice the sign was flipped. This is because when you multiply or divide by a negative number, you must always flip the sign!</em>

<u>Now, for the graph:</u>

-------------------------------------------------------------------------------------------------------------

For < or > signs, it should be an open circle. For $\leq$ or $\geq$ signs, it should be closed.

Since $x$ is less than 6, it should go to the left. Since it's a < symbol, it should be open. Therefore your answer is B.

(looks like you were right!!)
