Answer:

y = -x-3

x-y = -3

x - 2y = 10

Step-by-step explanation:

x − 3y = 6

Slope intercept form is y = mx +b

We need to solve for y

Subtract x from each side

x-x-3y = -x+6

-3y = -x +6

Divide each side by -3

-3y/-3 = -x/-3 +6/-3

y = 1/3 x -2

Standard form is Ax +By = C

y = -x-3

Add x to each side

x-y = -x+x-3

x-y = -3

y = 1/2x -5

We do not like fractions in standard form, so multiply by 2

2y = 2*1/2x -2*5

2y =x-10

Subtract x from each side

-x +2y = x-x-10

-x+2y = -10

We like to have the coefficient on x be positive

Multiply by -1

x - 2y = 10

the diameter of earth is 7917.5 mi and the diameter of mercury is 3032 mi. how many times can mercury go inside earth. use 3.14
Law Incorporation [45]

Answer:

Mercury can enter 6.8 times inside the earth

Step-by-step explanation:

To solve this problem we have to calculate the volumes

First we calculate the radius

radius earth = 7917.5mi /2 = 3958.75mi

radius mercury = 3032mi / 2 = 1516mi

To calculate the volume of earth we have to use the following formula:

V = volume

r = radius  = 3958.75mi

π = 3.14

V = ⁴⁄₃πr³

we replace with the known values

V = ⁴⁄₃ * 3.14 * (3958.75mi)³

V = 4.187 * 15671701.56 mi³

V =  65617414 mi³

The volume of earth is 65617414 mi³

To calculate the volume of mercury we have to use the following formula:

V = volume

r = radius  =  1516mi

π = 3.14

V = ⁴⁄₃πr³

we replace with the known values

V = ⁴⁄₃ * 3.14 * ( 1516mi )³

V = 4.187 * 2298256 mi³

V =  9622797 mi³

The volume of mercury is 9622797 mi³

Now we divide the earth volume by the mercury volume

65617414 mi³  / 9622797 mi³  = 6.819

round to the nearest tenth

6.819 = 6.8

Mercury can enter 6.8 times inside the earth
