90,000 because 9 is in the thousandths place and rounded up is 90,000
Answer:
Infinitely many.
Step-by-step explanation:
3x + 2y = 4
-6x - 4y = -8
Note that the second equation is obtained from the first by multiplying the first one by -2. Thus the graph of the 2 equations is the same line and there are infinitely many solutions.
12+40+28+12= 92
40-12= 28
92+28= 120
28-12= 16
120+16= 136
P=136
Let's say H represents the number of Hip-hop songs and P the number of Pop songs:
The first equation that describes the number of songs: H + P = 25
The second equation is for the price: 2H + 3P = 60
If you solve the system of equations you get P = 10 and H = 15
