Answer:

$10^{13}$ galaxies.

Step-by-step explanation:

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

The Milky Way galaxy $10 * 10^{10}$ 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 $10^{13}$ .

3. x + 4y = 30<br> x - 2y = 0

kolbaska11 [484]

Answer:

Step-by-step explanation:

Given that:

x + 4y = 30

x - 2y = 0

Subtracting both equations:

6y = 30

y = 30/6

y = 5

Putting in above equation

x + 4(5) = 30

x + 20 = 30

x = 10

Answer:

y=-2x-5

Step-by-step explanation:

y-y1=m(x-x1)

y-(-7)=-2(x-1)

y+7=-2x+2

y=-2x+2-7

y=-2x-5
