Answer:

If $x = -3$ and $y = 2$ , then $|5x-2y|-|3x| = 10$

Step-by-step explanation:

This is a problem that utilizes both substitution and the order of operations.

$|5x-2y|-|3x| = \\|-15-(2)(2)|-|(3)(-3)| =\\ |-15-4|-|(3)(-3)| =\\|-19|-|(3)(-3)| =\\19-|(3)(-3)| =\\19-|-9| =\\19-9 =\\10$

Step-by-step explanation:

$\frac{2x}{5} + \frac{1}{3} = \frac{7x - 2}{15}$

$\frac{6x + 5}{15} = \frac{7x - 2}{15}$

$6x + 5 = 7x - 2$

$6x - 7x = - 2 - 5$

$- x = - 7$

$x = 7$

Zach has a terrarium with the dimensions of 20 by 8 and the terrarium was filled with 3 inches of sand.Zach gets a new terrarium

Vladimir79 [104]

Answer: the sand in the new terrarium is 2 inches deep.

Step-by-step explanation:

Zach has a terrarium with the dimensions of 20 by 8 and the terrarium was filled with 3 inches of sand. It means that the volume of sand that this terrarium contains is

20 × 8 × 3 = 480 inches³

Zach gets a new terrarium that is larger with the dimensions of 10 by 24. If Zach moved the existing sand in the new terrarium and the height of the sand is represented by h, then the volume of sand into he new terrarium is

10 × 24 × h = 240h

Since the volume of sand in both terrariums is equal, then

240h = 480

h = 480/240

h = 2 inches
