Answer:

x = 1 (Option C)

Step-by-step explanation:

3x - 4y = -5 (1)

-3x - 4y = -11 (2)

On adding

3x - 4y - 3x - 4y = -11 + 5

6x = 6

x = 6/6

x = 1

Elimination method is a method of eliminating one of the variables from the two equations whose remaining variables will be simplified..

3x - 4y= -5 (×1) 3x - 4y= -5

-3x - 4y= -11 (×1) <u>-3x</u><u> </u><u>-</u><u> </u><u>4y</u><u> </u><u>=</u><u> </u><u>-11</u><u> </u><u>(</u><u>-</u><u>)</u>

6x = 6

6x/6 = 6/6

x = 1

the value of x is <em><u>1</u></em>

Answer: Option [C]

Answer:

1 = 175ft cubed

2 = 58m cubed

3 = 140m cubed

4 = 180in cubed

Step-by-step explanation:

You have to split these complex shapes into parts and find the volume of each part.  Then, add the parts' volumes together, which will be the total volume of these.  The equation is V=bhw.  V means volume, b means base, h means height, and w means width.  Hope this helps!
