Answer C and D please

DENIUS [597]

Answer:

C. solution:

3(3c-2) = 5(2c-1)

or, 9c-6 = 10c-5

or, -6+5 =<em> </em>10c-9c

or, -1 = 1c

Hence, c = -1.

D. solution:

5(5-2a) = 4(6-a)

or, 25-10a = 24 - 4a

or, 25-24 = -4a+10a

or, 1 = 6a

or, 1/6 = a

Hence, a = 1/6.

Cual es el volumen del cubo de rubick cuya arista mide 3 cm

Natasha2012 [34]

For this case we are asked the following question:

"What is the volume of the rubick's cube whose edge measures 3 cm"

By definition, the volume of a cube is given by:

$V = l ^ 3$

Where:

l: Is the side or the edge of the cube

According to the statement we have:

$l = 3 \ cm$

Substituting:

$V = 3 ^ 3\\V = 3 * 3 * 3\\V = 27$

Finally, the volume of the cube is $27 \ cm ^ 3$

Answer:

$27 \ cm ^ 3$
