0.1(x-8) = 0.90.1x - 0.8 = 0.90.1x = 0.9 + 0.80.1x = 1.7x = 1.7 / 0.1x = 17
-9/44y = 2 5/11To add the mixed number 2 5/11, we first convert it to an improper fraction:2 5/11 = 22/11 + 5/11 = 27/11
Now we have:-9/44y = 27/11y = (27/11) / (-9/44)y = (27/11) * (-44/9)y = -1188/99y = -12
Therefore, the solutions to the equation are x = -0.2 and x = 0.2.
0.1(x-8) = 0.9
0.1x - 0.8 = 0.9
0.1x = 0.9 + 0.8
0.1x = 1.7
x = 1.7 / 0.1
x = 17
-9/44y = 2 5/11
To add the mixed number 2 5/11, we first convert it to an improper fraction:
2 5/11 = 22/11 + 5/11 = 27/11
Now we have:
(3x - 0.6)(x + 0.2) = 0-9/44y = 27/11
y = (27/11) / (-9/44)
y = (27/11) * (-44/9)
y = -1188/99
y = -12
Expanding the left side, we get:
3x^2 - 0.6x + 0.6x - 0.12 = 0
3x^2 - 0.12 = 0
3x^2 = 0.12
x^2 = 0.12 / 3
x^2 = 0.04
x = ±√0.04
x = ±0.2
Therefore, the solutions to the equation are x = -0.2 and x = 0.2.
