Can anyone help me with this problem..please! : Solve for m: N= mn / m - n?

If you mean N=(mn)/(m-n)\nThen m=[mn/N]+n\n\nIf you mean N=[mn/m]-n\nThen m=(mn)/(N+n)

You can easily solve this by realizing (4m - 3n)(4m + 3n) has a pattern (a + b)(a - b), which equals to a^2 - b^2\n\nSo,\n(4m - 3n)(4m + 3n) = (4m)^2 - (3n)^2\n= 16m^2 - 9n^2

Observe:\nsum= 4+12+24+40+60+.....+t(n-1)+t(n)\nsum=       4+12+24+40+.....+t(n-2)+t(n-1)+t(n)\nSubtracting,\nt(n)=4+8+12+16+20+.........upto n terms\n      = n/2[2*4+(n-1)*4]\n      = n/2[4+4n]=n[2+2n]

m = (9-(-1))/(-2-3) = 10/-5 = -2\n\n-1 = -2(3) + b\nb = -1 + 6\nb = 5\n\n\nf(x)= -2x + 5\n\n\nYou got the slope sign reversed.  Be careful about that.  Otherwise, it's correct!

I suppose the problem was already due so I'll finish it for you now.\n\nF=m*a\na=F/m= 2*10^6N/1.2*10^6kg = 1.67m/s^2 * g/9.81m/s^2 = 0.17g

2.5 m= - 25.. are you trying to solve for M.... \nand -3.25t=-3.11 i am assuming you are trying to solve for T?\n\nfor the first one... 2.5m/2.5=-25/2.5 so m = 10\n\n2nd one .. -3.25t/-3.25= -3.11/-3.25\n\ni don't know if this is what u looking for

convert to Newtons from mN, then divide by gravity because F=mg. so you get .00000780/9.8

Use the law of sines\n\nn/sin(N)=m/sin(M)\n\nso \n\nm = n*sin(M)/sin(N)\n\nPlug in the values and use your calculator.

come on. all these questions are almost EXACTLY the same. \np1v1/t1 = p2v2/t2 = nr = constant.\n(0.998atm)(2.1L) / (36+273K) = (0.9atm)v2 / (28+273K)\nand then solve for v2. and u get\nv2 = 2.268L\n\n3. p1v1 = p2v2 = nr/t = constant\n(1.08atm)(14.57mL) = (1.43atm)v2\nv2 = 11.0039mL.

You are solving for k so it you need to rewrite the problem to look like this k=z/(xy) where x=3, y=8, z=6 substitute the letters for numbers so k=6/(3*8) k=6/24 or k=1/4 to check just solve for any other letter such as z by using what you know of k and you should come out with z=6

PV = NRT, solve for N, note that T is absolute temperature in kelvins
