PLEASE HELP ME FIND THE AVERAGE!
Studentka2010 [4]

Answer:

The answer is 22

The sum of two numbers is 48:

x + y = 48      ⇒ x = 48 - y

One third of one number is 5 greater than one sixth of another number:  

1/3x =5  + 1/6 y    

1/3(48 - y) = 5 + 1/6y

1/3 * 48 - 1/3 * y = 5 + 1/6 y

16 - 1/3y = 5 + 1/6y

16 - 5 = 1/6y + 1/3y

11 = 1/6y + 2/6y

11 = 3/6y

y = 11 * 6 / 3

y = 22

x = 48 - y

x = 48 - 22

x = 26

The smallest number is 22.

X+2x + ___=5x. What goes on the blank
Helen [10]

Answer:

2x

Step-by-step explanation:

The equation would be x+2x+2x=5x.

You can rewrite the equation as 1x+2x+2x=5x because that is the same thing.

Then you combine all of the like terms, and because they all have an x you just add them together.

Hope this helps!

Write an equation in slope intercept form for a line perpendicular to the line
konstantin123 [22]

Answer:

y=(1/3)x- 4/3

Step-by-step explanation:

If two lines are perpendicular to each other, then the slopes will be the negative inverse to each other.

Example:

the negative inverse of 2 is -1/2

the slope of  y=-3x+2  is -3

the negative inverse of -3 is \dfrac{1}{3}

So we have the perpendicular line be :y=\dfrac{1}{3}x+b

Since it also go through (4,0)

plug in we get 0 = \dfrac{4}{3}+b

b=-\frac{4}{3}

So the equation would be

y=\frac{1}{3}x - \frac{4}{3}
