Pls help​

1.) -2 1/4 + 2 1/5 =

   (-9/4)5 + (11/5)4 =

   -45/20 + 44/20 =

   -1/20 =

2.) -5  ÷ 2/4 =

    -5/1  ÷ 2/4 =

    -10/4 =

    -2 2/4 or -2 1/2

3.) (-5/6) - (3/2) =

    (-5/6) - (3/2)3 =

    (-5/6) - (9/6) =

    -14/6 or -2 2/6

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

answer4 to the second power is 16

and 4 to the third power is 64,
