Since she has "no more than $40 to spend" we know that the the symbol must be "less than or equal to"
. Now we can eliminate the first and second choices because they are "greater than or equal to".
Next, we can figure out how to model this situation. There is a flat $5 fee and each song is $2. We can model this with 2s+5 ($2 per son plus $5).
The answer is 
Hope this helps!
Addition Property of equality (+6 on both sides) V<19 any number less than 19 = V
2y+x-2y+3x=180
x=45
2x-15=-2y+3x
y=30
Answer:
for question 4, 1/3 is the probability since there are 6 sides and there are two numbers on a die less than 3, 2 and 1.
2 and 1 are 2 of the 6 numbers on the die.
so 2/6
but we have to simplify!
divide 2 by 2 and 6 by 2
1/3 done!
