music magic offers live streaming for $9.99 a month with downloads at $0.50 a song. You have $30 a month budgeted for this servi
marin [14]

Step-by-step explanation:

The equation 0.5s+ 9.99=30 describes the situation.

9.99 is the fixed amount

0.5 is the cost for each song download

30 is the maximum amount spend for a month

Here 's' represents the number of songs download

0.5s+ 9.99=30 means

0.5 times the number of songs plus the fixed cost 9.99 should be equal to 30 dollars.

The solution to this equation is s=40.02.

s= 40.02  means 40 songs can be downloaded as per the budget

Alexander says that 3x + 4y is equivalent to (3)(4) + xy because of any order, any grouping. Is he correct why or why not
snow_lady [41]

Answer:

Alexander is incorrect because the expressions are not equivalent.

Step-by-step explanation:

If the expression is evaluated for any value of x, y; the result will not be same.

For instance, let assume x = 1 and y = 2

3x + 4y = 3 + 4 = 7

(3)(4) + xy = (3)(4) + (1 * 2) = 12 + 2 = 14

So, the expressions are not the same and Alexander is incorrect.
