Answer:
Use the Triangle exterior angle theorem. The definition of this theorem, is that the exterior angle you are solving for is the sum of the two opposite interior angles. Set the equation:
80 + x = 3x - 22
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract x and add 22 to both sides.
80 (+22) + x (-x) = 3x (-x) - 22 (+22)
80 + 22 = 3x - x
Simplify.
102 = 2x
Isolate the variable, x. Divide 2 from both sides.
(102)/2 = (2x)/2
x = 102/2
x = 51
Check. Plug in 51 to the equation given.
80 + x = 3x - 22
80 + (51) = 3(51) - 22
131 = 153 - 22
131 = 131 (True).

Answer:
- 7 / 4
Step-by-step explanation:
( x1, y1 ) = ( 1, 10 )
Here,
x1 = 1
y1 = 10
( x2, y2 ) = ( 5, 3 )
Here,
x2 = 5
y2 = 3
Formula : -
Slope = ( y2 - y1 ) / ( x2 - x1 )
Slope = ( 3 - 10 ) / ( 5 - 1 )
Slope = - 7 / 4
Proper fraction = - 7 / 4
Answer:
ok simple. lets start with 15/30, 15/30 is basically 1/2 because 15 is half of 30
1/3 is not to the half point of 3 the half point of 3 is 1/5. 2/3 is more than halfway of 3 as it is more than 1.5/3. Do I make sense?
