can you ]show the work plz

I'll  just take her to Alabama. I'll give her my love.

Isn't it -3?

Use an inequality:

x + 9 > 28

Therefore x > 19.

She could have ran for 19 minutes yesterday.

That's not normal......

This is a big problem for traditional Chinese, like me....(although Im a teenager lol)

This cannot happen.

This will never happen in Chinese regions like mainland China, Hong Kong.

If 34x + 6 congruent 2 mod 20, 34x + 4 is divisible by 20.

We use trial and error(again) and test for each negative integer from -1.

34(-1) + 4 = -30 which is not divisible by 20.

34(-2) + 4 = -60<-- OMG answer already here. It is divisible by 20.

Therefore the largest negative integer which satisfies the congruence is -2 :)

I think I saw the pattern:

2 + 2 = 5

5 + 5 = 2

Therefore in this question:

a + a = b

b + b = a

Therefore when 9 + 9 = 15 then 15 + 15 = 9.

First calculate the horizontal distance from Tammy to the helicopter.

\(\cos 12 = \dfrac{\text{Horizontal distance}}{400}\\ \text{Horizontal distance} =400 \cos 12\)

Add 700 to the result to obtain the horizontal distance from Rusty to the helicopter.

Horizontal distance from Rusty to the helicopter = 400 cos 12 + 700 = 1091.3 meters :)

if you're talking about how many years apart, its 254,965,000 years apart.

im eating tape while typing this, it isnt that bad

Thanks so much!

n + 4m - 2p - 2m - 3p

= (4m - 2m) - (2p + 3p) + n <-- combine like terms.

= 2m - 5p + n :D

Looks like someone calls you for help, Melody.

If \(3x+7\equiv 2\pmod{16}\), \(3x+5\) is divisible by 16.

The smallest integer solution for x is 9. where 3(9) + 5 = 32 is divisible by 16.

Substitute x = 9, 2x + 11 = 29.

29 mod 16 = 13.

Let's test for the 2nd smallest integer solution for x, which is 25. where 3(25) + 5 = 80 is divisible by 16.

2x + 11 = 61.

61 mod 16 = 13.

Good!!

Therefore, the answer is 13 :D

Good Job!

As you required.

The solution of r should be a 4-digit solution, as the question requires......

I will solve both situations given by hectictar.

Situation 1:

\(\sqrt{79}-5x = x-11\\ 6x = \sqrt{79} + 11\\ x = \dfrac{\sqrt{79}+11}{6}\)

Situation 2:

\(\sqrt{79-5x}=x-11\\ 79-5x = x^2 -22x+121\\ x^2-17x+42=0\\ (x-14)(x-3) = 0\\ x = 14\text{ OR }3\)

You have made a small mistake Max :)

\((r+2)^2=(r+1)^2\\ r+2=\pm (r+1)\\ \text{clearly r+2 can not equal r+1}\\ r+2=-(r+1)\\ r+2=-r-1\\ 2r=-3\\ r=-1.5\)

It would have been easier just to solve it as it was.

\(r^2 + 4r + 4 \equiv r^2 + 2r + 1 \pmod{55}\\ 2r \equiv-3 \pmod{55}\\ r \equiv -1.5 \pmod{55}\)

there isn't, pie is circle

The square root of pi is 1.7724538509055159

so there are alot of ways i guess.

cause 1+1 can equal x, so just use ur brain and find 'x'
