Jeffrey purchased and downloaded 12 songs on monday. he purchased 3 songs on tuesday. the cost to download each song is $2. write a numerical expression to represent this situation

 2 × 12 + 2 × 3 or 2 × (12 + 3)

Step-by-step explanation:

Here, the cost of one song = $ 2

If the downloaded song on Monday was 12,

Then, the total money spend on Monday = 2 × 12

Similarly, If the downloaded song on Tuesday is 3,

Then, the total money spend on Tuesday= 2 × 3

Thus, the total cost of the songs on Monday and Tuesday = 2 × 12 + 2 × 3  Or  2 × ( 12 + 3)

Which is the required numerical expression.

By solving it we get = 2 × 15 = 30

Therefore, he spent $ 30 on Monday and Tuesday in downloading songs.

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)
