Answer:

Option A is correct

No values of x make the equation true              

Step-by-step explanation:

Given the equation:

7 +2x = 2(x-1)+4

Using distributive property: a \cdot(b+c) = a\cdot b+ a\cdot c

then;

7+2x = 2x -2 +4

⇒7+2x = 2x +2

Subtract 2x from both sides we have;

7 = 2 False

⇒No values of x make the equation true.

Answer is A

7 + 2X = 2(X-1) + 4

7 + 2X = 2X-2+4

7 + 2X = 2X + 2 whether 2X = 2X-5  or 5 + 2X = 2X still  0 = 5 Or 0= -5 which is not possible

Answer:

10^{13} galaxies.

Step-by-step explanation:

There are about 10^{24} stars in the universe.

The Milky Way galaxy10 * 10^{10} stars.

All we need to do to find the number of galaxies is to divide the total number of stars in the universe by the number of stars in the Milky Way:

Number of galaxies = (Number of stars in the universe) / (Number of stars in the Milky Way)

Number of galaxies = \frac{10^{24}}{10 * 10^{10}}

N = \frac{10^{24}}{10^{11}}

N = 10^{24 - 11} = 10^{13}

The number of galaxies in the universe is approximately 10^{13}.
