Solve the following congruence for 'x' in terms of 'y': 2x + 3y is congruent to 1 (mod 81).

So far I've done:

(2x + 3y) - 1 + 81k

2x - (3y + 1) = 81k

2x = (-3y + 1)mod81

however my teacher said we can't divide by 2. I was wondering if I was on the right track, and if so, what to do next?

I can't figure out what color/type of eyeliner to use that won't look harsh. I really like bringing out the green in my eyes. help??

So there are two questions that I supposedly answered on here that I swear on my life I never answered...even the way the answers are given totally does not sound like how I would say something...what gives? has this happened to anyone else?

And it wasn't anybody in my family on my account or anything else.

I got a 1380 on the 1600 scale (740 critical reading and 640 math) and a 2090 on the 2400 scale

I have no idea how good this is...I'm thinking I should take them again to improve my math score?

(a) Determine the current in each resistor.

1 A (R1)

2 A (R2)

3 A (R3)

(b) Determine the potential difference across each resistor.

4 V (R1)

5 V (R2)

6 V (R3)

1 & 2 are parallel, 3 is in a circuit series. It's a 12 volt battery.

I also found out that the potential difference across R3 is 6.4 volts

I might be going to a concert at the Beacon Theatre in NY and I'm not sure which would be better-first row Upper Balcony, or third to last row in Loge?

The fundamental frequency of an open organ pipe corresponds to the note middle C (f = 261.6 Hz on the chromatic musical scale). The third harmonic (f3) of another organ pipe that is closed at one end has the same frequency. Compare the lengths of these two pipes.

Some of them are really into the whole Twilight/New Moon thing, so I was wondering what I could get for them (preferably under $10)? I know that they have stuff at Hot Topic, but I looked and there wasn't anything great there.

I have pale skin with pink undertones (half Irish and half italian, and I got the Irish skin =|), dark brown hair, and blue-green eyes. I really want to bring my eyes out more but I have no idea how to do that. What would you suggest? Black or brown eyeliner? And what colors would look good with my eye color/skin tone?

Emily takes a trip, driving with a constant velocity of 85.5 km/h to the north except for a 22 min rest stop. If Emily's average velocity is 72.8 km/h to the north, how long does the trip take?

(in hours)

my hair grows really slowly, i wanted to buy the hair, skin and nails formula from GNC, does anyone know if it works? the one with biotin in it. if not, do you know any products that do work?

Anything unique and related to Twilight would be awesome =]

I get that the poem is about a family gathering in the summer, but why are the children crying for their mothers at the end?
