\frac{AD}{AB} =\frac{DE}{BC}

\frac{2}{6} = \frac{x}{12}

6x = 24\\x=4

What is the equation of a line , in a slope -intercept form , that passes through (5,-3) and has a slope of 2/3? A. y-3= 2/3(x+5
zmey [24]
Ur asking for slope intercept form, but ur answer choices are in point slope form....so I am gonna find the answer in point slope form.

y - y1 = m(x - x1)
slope(m) = 2/3
(5,-3)....x1 = 5 and y1 = -3
now we sub...but pay very close attention to ur signs
y - (-3) = 2/3(x - 5) = 
y + 3 = 2/3(x - 5) <=== ur answer in point slope form

zalisa [80]

Answer: 135%

Step-by-step explanation: Given

Europe =  35%

Asia = 10%

Australia* = 20%

North America = ?

To find

Europe + Asia + Australia =

35% + 10% + 20% = 65%

Then the total subtracted from the given

200 - 65 = 135

Therefore,

North America = 135%

Confirm

To make sure that is the correct answer, add it all together.

35 + 10 + 20 + 135 = 200

Which means it is correct.
