Answer:
x = -1/9
Step-by-step explanation:
first let's think of x as 1x so than x^2 is basically 1x.
you bring down 8x + 1 = 0 so you have x + 8x + 1 = 0.
than you add x and 8x which equals 9x.
you bring the problem down one more time so 9x + 1 = 0.
you subtract 1 from each side so the 0 becomes because 0 - 1 is -1.
So than you bring the rest of the problem down 9x = -1
Last thing you do is divide 9 from both sides which x = -1/9.
Answer:

Step-by-step explanation:
The vertical angles have the same measure, so ...
3x +50 = 6x -10
60 = 3x . . . . . add 10-3x
20 = x . . . . . . divide by 3
Answer:
$4.75
Step-by-step explanation:
11-(6+0.25)
11-6.25=4.75
Answer:
1) 145°
2) 20°
3) x = 7 ; measurement of the missing angle = 24
Step-by-step explanation:
1) supplement = 180°, 180 - 35 = 145
2) complment = 90° , 90 - 70 = 20
3) the figure is a right angle so the measurement is 90°
66 + (4x-4) = 90
62 + 4x = 90
4x = 28
x = 7
4(7) - 4
28 - 4
= 24
