1 Andre tried to solve the equation: 1/4(x+12)=2. What was his mistake. A. 1/4(x+12)=2
B. 1/4x=-10
C. x=-40​

the correct answer is x=-4

Step-by-step explanation:

the mistake he made is writing 1/4x=-10 instead of 1/4x=-1

He should have wrote -1 instead of -10

1/4 x =2-3=-1

Step-by-step explanation:

In this line he made a mistake. He wrote -10 instead of -1

so x = -4

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)

answer is 67%
