To solve, we must get x by itself. the first step we must take is to remove all of the parentheses. To do this, we must use distribution to multiply 5 by x - 6.

5(x - 6) = 3x - 18 + 2x

5x - 30 = 3x - 18 + 2x

Next, we must add like terms.

5x - 30 = 5x - 18

Finally, we must get x by itself. to do this, we must subtract 5x from both sides.

5x - 30 - 5x = 5x - 18 - 5x

Then, we add like terms again.

-30 = -18

Because this is a false statement, the equation is a contradiction.

What happens to the volume of a sphere when its radius is doubled?
Alik [6]
Vsphere=(4/3)pir^3

when we replace r with 2r

newvsphere=(4/3)pi(2r)^3
newvsphere=(4/3)pi8r^3
newvsphere=8((4/3)pir^3)
newvsphere=8(vsphere)
it's volume is multipliied by 8

that is choice C, because 2^3=8, it's vollume is 8 times original voluem


answer is C

Viefleur [7K]

Answer:

distance between L and M

Step-by-step explanation:

The question is given is the image in the image attached.

A number line is shows the representation of numbers on a line, it is used to perform arithmetic operations lie subtraction, addition.

The distance between two points A and B on a number line is given by the formula:

Distance = |A - B|

On the number line the points L is at -6, M is at -2 and N is at 4. Hence

Distance between L and M = |M - L| = |-2 - (-6)| = | -2 + 6| = |4| = 4 unit

Distance between M and N = |N - M| = |4 - (-2)| = | 4 + 2| = |6| = 6 unit

Distance between L and N = |N - L| = |4 - (-6)| = | 4 + 6| = |10| = 10 unit

Brooke measured the distance between L and M which is 4 units
