Answer:

A) 0.5 g/cm³

Step-by-step explanation:

To find volume, you must multiply length × width × height

So it would be 3 × 2 × 4

3 × 2 × 4 = 24

Volume = 24

Plug in both numbers into the equation for Density

12 ÷ 24 = 0.5

The density will be 0.5 g/cm³

Answer:

Q = -6

Step-by-step explanation:

To find the answer to this, you first must multiply the first function by 2:

2 x (x - 3y = 4)

2x - 6y = 8

Which then means that the second function is the same. This means that to find Q you need to find the number that changed +Qy into -6:

2x - 6y = 8

2x + Qy = 8

The 2x's cancel out, and then remove the equals and the 8:

-6y = Qy

<h3>So Q must be -6</h3>
