Colton solved an equation incorrectly, as shown below:
step 1: x – 13 = 26
step 2: x = 26 – 13
step 3: x = 39
which statement best explains why step 2 is incorrect in colton's solution?
a he did not subtract 13 from 26.
b he did not multiply 26 by 13.
c he did not add 13 to 26.
d he did not divide 26 by 13.

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)

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total

the answer is 8/21

hope this
