Answer:

x=10

Step-by-step explanation:

\mathrm{Subtract\:}55\mathrm{\:from\:both\:sides}\\3x+55-55=9x-5-55

\mathrm{Simplify}\\3x=9x-60

\mathrm{Subtract\:}9x\mathrm{\:from\:both\:sides}\\3x-9x=9x-60-9x

\mathrm{Simplify\:}again\\-6x=-60

\mathrm{Divide\:both\:sides\:by\:}-6\\\frac{-6x}{-6}=\frac{-60}{-6}

\mathrm{\:Simplify\:one\:more\:time}\\x=10

I hope this helps you out!

Have a wonderful afternoon!

Answer:

x = 10

Step-by-step explanation:

3x + 55 = 9x - 5  (add 5 to both sides)

3x + 55 + 5 = 9x - 5 + 5

3x + 60 = 9x  (subtract 3x from both sides)

60 = 9x - 3x

60 = 6x (rearrange)

6x = 60   (divide both sides by 6)

x = 60/6

x = 10

Bumek [7]

Answer:

X = 13

Step-by-step explanation:

42 - X = 29

Subtract 42 from each side

42-42 - X = 29-42

-X = -13

Multiply each side by -1

What is the equation of the line, in point-slope form, that goes through (-2,-1) and is perpendicular to y=5x+3?
Lemur [1.5K]

The correct answer is B. y + 1 = -1/5 (x + 2)

I got B by putting the numbers in point-slope form which is y - y1 = m ( x - x1 ) so I got:     y + 1 = m ( x + 2 )

Then to find m(the slope) I knew if the slope was 5 it would be parallel to y=5x+3 so therefore -1/5 would be perpendicular to the line y=5x=3.

Hope that helps!!
