Answer:

x = 20

Step-by-step explanation:

the angles shown are supplementary

supplementary angles add up to 180°

hence, 5x - 7 + 3x + 27 = 180

==> combine like terms

8x + 20 = 180

==> subtract 20 from both sides

8x = 160

==> divide both sides by 8

x = 20

Write two decimals that are equivalent to 8.1

8.10 and 8.100 because its about significant figures. There can be an infinite number of zeros after the 1.

$2x^{2/3}+3x^{1/3}-2=(2x^{1/3}-1)(x^{1/3}+2)=0$

Then

$2x^{1/3}-1=0\implies2x^{1/3}=1\implies x^{1/3}=\dfrac12\implies x=\dfrac18$

$x^{1/3}+2=0\implies x^{1/3}=-2\implies x=-8$

(assuming you are solving over the real numbers)
