Answer:
x = 40
Step-by-step explanation:
If you add the total of 3 angles in a STRAIGHT line, you have to get 180 in total.
So, x = 180 - ( 80 + 60 )
= 180 - 140
= 40
Rearrange the equation to get:
y = 3x - 7
From this you can see that:
m = 3, b = -7
Answer:
-4x-2 = -2/3
-4x = -2/3 + 2
-4x=4/3
therefore x = (4/3) divide by -4
x = ( 4/3) / -4
x = 4/3 x -1/4
x = -1/3
