Two numbers sum to 53. Twice the first subtracted from the second is 8. Find the numbers.

If two lines have the same slope, they are parallel. True of false

Simplify the expression. (-2 - 2i) (-4 + 6i) >8 - 4i >8 - 12i >20 - 4i >-4 - 4i

Nick's telephone company charges $0.05 Per minute for weekend calls and $0.09 Per minute for calls made on weekends. This month Nick was billed 631 minutes. The charge for these minutes was $34.

He makes $316 a week and $23 for every sale he makes. He has to pay his rent this week that is $500, so he will need to make at least that amount.
