Answer:

Step-by-step explanation:

you have set them up so you can cross multiply.

(3 * x) = (7 * 27)

3x = (189)

to solve for x we need to isolate the variable, so divide both sides by 3:

x = 63

Answer:

37 degrees.

Answer:

a = 3
b = -18

Step-by-step explanation:

Using the least common denominator, we have ...

$2-\dfrac{x+1}{x-2}-\dfrac{x-4}{x+2}\\\\=\dfrac{2(x-2)(x+2)-(x+1)(x+2)-(x-4)(x-2)}{(x-2)(x+2)}\\\\=\dfrac{2(x^2-4)-(x^2+3x+2)-(x^2-6x+8)}{x^2-4}\\\\=\dfrac{(2-1-1)x^2+(-3+6)x+(-8-2-8)}{x^2-4}=\boxed{\dfrac{3x-18}{x^2-4}}$

The values of a and b are ...

a = 3

b = -18
