Solve for x: -6 = -2 (x+3) -6 = -2 (x+3) is equivalent to -2 (x+3) = -6: -2 (x+3) = -6 Divide both sides of -2 (x+3) = -6 by -2: (-2 (x+3))/(-2) = (-6)/(-2) (-2)/(-2) = 1: x+3 = (-6)/(-2) The gcd of -6 and -2 is -2, so (-6)/(-2) = (-2×3)/(-2×1) = (-2)/(-2)×3 = 3: Answer: | | x+3 = 3 x=0
Use the formula: F=G.M.M/r^2, where G=Newton's gravitational constant, M=mass of the bowling b***s, r=the distance between them.
40*5/8=200/8=25
9x-9= -9
9x=-9+9
9x=0 divide both sides by 9
x=0/9
x=0
Solve for Z: Z^4 = -(3 i)-5 -(3 i)-5 = -5-3 i: Z^4 = -5-3 i Taking 4^th roots gives (-5-3 i)^(1/4) times the 4^th roots of unity: Answer: | | Z = -(-5-3 i)^(1/4) or Z = -i (-5-3 i)^(1/4) or Z = i (-5-3 i)^(1/4) or Z = (-5-3 i)^(1/4)
a = 1/4 (49-3 sqrt(249)) = 0.415200 and b = 1/4 (49+3 sqrt(249)) = 24.0848
a = 1/4 (49+3 sqrt(249)) = 24.0848 and b = 1/4 (49-3 sqrt(249)) = 0.415200

No it doesn't (3 1/2)^2 = (7/2)^2 = 49/4 = 12 1/4
or another way (3 1/2)^2 = (3 + 1/2)^2 = (3+1/2)(3+1/2) = 9 + 1/2(3) + 1/2(3) + 1/2(1/2) = 9 + 3 + 1/4 = 12 1/4
what do you mean by formula mass?
Divede numerator by 3 and denominator by 3
12/1287
Divide by 3 again
4/429 As an aside: If you add the digits of a number and the result is a number divisible by three, then the original number is divisible by three also (that is what I did here)
Is it? It is! It felt like a Monday to me this morning.
It means: 6.6666666666666667 X 10^25
It looks like you are trying to calculate a monthly payment on a loan of $8,700 @ 9.31% compounded monthly over a period of 3.5 years.
Your answer should be $243.52. Good luck.
(3x/4) + (2x/3)=51
9x/12 + 8x/12=51
17x/12=51 cross multiply
17x=612 divide both sides by 17
x=612/17
x=36
hi the answer to 15 + 19 =34
thanks!
what does the n stand for n+13=75
n + 13=75
n=75-13
n=62
Solve for x: (17 x)/12 = 51 Multiply both sides of (17 x)/12 = 51 by 12/17: ((12×17 x)/(17))/(12) = 12/17×51 12/17×51 = (12×51)/17: (12×17 x)/(17×12) = (12×51)/17 (12×17 x)/(17×12) = (17×12)/(17×12)×x = x: x = (12×51)/17 51/17 = (17×3)/17 = 3: x = 12×3 12×3 = 36: Answer: | | x = 36
That is NOT an equation! What are you trying to calculate? It looks like compound interest? let us know what you want to calculate.
