There are 206 bones in the body. What fraction represents the number of bones in one hand (27) compared to the total number of b
Law Incorporation [45]

Answer:

\frac{27}{206}

Step-by-step explanation:

Let

x -----> the number of bones in one hand

y -----> the total number of bones in the body

we know that

The fraction that represents the number of bones in one hand compared to the total number of bones in the body, is equal to divide the number of bones in one hand by the total number of bones in the body,

we have

x=27\ bones\\y=206\ bones

\frac{x}{y} =\frac{27}{206}

Explain how to rewrite the equation -2x - 6y = 18 in slope-intercept form.
MrMuchimi

Answer:

y = -1/3x -3

Step-by-step explanation:

-2x - 6y = 18

We want to solve for y since the slope intercept form is y =mx+b where m is the slope and b is the y intercept

Add 2x to each side

-2x-6y +2x = 2x+18

-6y = 2x+18

Divide each side by -6

-6y/-6 = 2x/-6 + 18/-6

y = -1/3x -3

This is in slope intercept form with the slope -1/3 and the y intercept -3
