Use the three steps to solve the problem.
the length of a rectangle is 2 inches less than 3 times the number of inches in its width. if the perimeter of the rectangle
is 28 inches, what is the width and length of the rectangle?
(width sin., length plin.)

answer: the length is 7.3 and the width is 20.7.

step-by-step explanation: 28/3 = 9.3)(9.3 - 2= 7.3 is length. 20.7 is the remainder.

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)

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this
