2. Justify each step in solving the equation 4x = 7(x - 3) by writing a reason for each statement.

Statement

Reason

1. given

1. 4x = 7(x-3)

2. 4x = 7x - 21

2.1

3.

3.-3x = -21

4.

4. X = 7

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)

yes

step-by-step explanation:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
