Answer:

x = 8/3

y = 7/3

Step-by-step explanation:

In a parallelogram the diagonals bisect each other.

So 2x = y + 3

x + y = 5

Then you set them up to do combination/elimination to solve for the two variables.

2x-y = 3

Then you add the two equations together

3x = 8

Solve for x

x = 8/3

Then solve for y by plugging it into a equation

x + y = 5

8/3 + y = 5

8/3 - 5 = -y

8/3 - 15/3 = -y

-7/3 = -y

y = 7/3

The mass of the sun is 2.13525×10^30 kilograms. The mass of Mercury is 3.285×10^23 kilograms.

Rama09 [41]

Answer:

The mass of Sun is $65\times 10^5$ times greater than mass of Mercury.

Step-by-step explanation:

We are given that

Mass of the sun= $M=2.13525\times 10^{30}$ kg

Mass of Mercury, $m=3.285\times 10^{23}$ kg

We have to find how many times greater is the mass of the sun than the mass of Mercury.

Mass of sun/Mass of mercury= $\frac{2.13525\times 10^{30}}{3.285\times 10^{23}}$

Mass of sun/Mass of mercury $=0.65\times 10^{30-23}$

Using the property

$a^x/a^y=a^{x-y}$

Mass of sun/Mass of mercury $=0.65\times 10^{7}$

Mass of sun/Mass of mercury $=65\times 10^5$

Mass of Sun= $65\times 10^5$ times Mass of Mercury

Hence, the mass of Sun is $65\times 10^5$ times greater than mass of Mercury.

A running track at a school is shaped like oval. The track is 1/2 miles long . Mr. Perez puts a marker down every 1/8 mile .

Lunna [17]

Answer:

4 markers

Step-by-step explanation:

1/2 miles divided by 1/8 miles equals 4 markers.

1/2 ÷ 1/8

Apply the fraction rule:

1/2 × 8/1

Cross cancel common factor 2:

= 4/1

= 4

Hope this helps!
