José and Nancy take care of animals when owners are away. José charges $15 plus $2 per animal. Nancy charges $5 plus $3 per animal. For how many animals do they charge the same amount? Solve the equation below to find out. * 15 + 2x = 5 + 3x

A. 3 animals
B. 4 animals
C. 10 animals
D. 15 animals

C. 10 animals

Step-by-step explanation:

This is how i do it

(you just rearrange the number so the you can add the x's together)

15 + -5 = -2x + 3x

15 + -5 = 10

-2x  + 3x = 1x or X

so you answer is:

X = 10

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)

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
