URGENT PLEASE HELP!!

Mathematics
1 answer:
Ivahew [28]3 years ago
3 0

Answer:

k = 3

Step-by-step explanation:

Subtract that one from the right side and then from the left side, so the equation should now look like (6 = 2k). Now you need to make the k be by itself to find what number it represents. So divide 2k by 2 and 6 by 2. So now the equation should look like (3 = k). (k = 3)

Select the correct answer.
dimulka [17.4K]

Answer:

<u>Tank 1 : </u>

height = 2x-2

length = 4x

y = l w h

  = (4x) (x) (2x-2)

  = (4x^{2}) (2x-2)

  = 8x^{3}-8x^{2}

<u>Tank 2: </u>

height = 6x

length = 2x-1

y = l w h

  = (2x-1) (x) (6x)

  = (2x^{2}-x) (6x)

  = 12x^{3}-8x^{2}

I think it is the second option but I am not sure because the picture is very unclear. Do double check with the answers I have worked out.

Hope this helps.

Sharon is making 100 liters of punch for a party. The punch contains ginger ale (g) and fruit (f). The cost of the ginger ale is
SIZIF [17.4K]

Answer:

12 liters of fruit.

88 liters of ginger ale.

Step-by-step explanation:

100 = g + f

130 = 1g + 1.5f 

f = 12 

because u can use elimination by multiplying equation 2 by -1 to cancel out g variable then combine both equations

g = 88

because plug in f's value of 12 to 1st equation then subtract 12 from each side
