Answer:
4/5
Step-by-step explanation:
4/5 because that would make five tries and he has made 4 with black so he has a 4/5 chance
It would be written as a fraction to make the exponent negative put it over one : 1/7^4
Answer:
ten stickers because 24 minus the 4 your friend gave you equals 20. divide that by the number of packs he bought and you get ten stickers per pack.

Answer:
x=3.5
Step-by-step explanation:
MN is divided in half because of MO. BN would equal 6, too. In all, LN should equal 12. So, your equation would be:
2x+5=12
Solve this equation:
2x=12-5
2x=7
x=3.5

Answer:
infinitely many solutions
Step-by-step explanation:
I assume that you meant
3x = -12y + 15 and x + 4y =5 (you accidentally omitted the 'y')
Multiplying the second equation by 3 yields
3x + 12y = 15
... which is identical to the first equation. Thus, the two lines coincide, and we conclude that there are infinitely many solutions.
