User: What is the solution set of the following equation?
-8x + x + 15 = -7x + 12

Weegy: INPUT THE NUMBERS like for f(2) you would put 2(2)^2-7(2)+3= the answer. thank you for using weegy spartan967|Points 20|

User: Solve for x.
5(2x - 1) = 6

Weegy: B.x = 11/10 jher000|Points 2543|

User: Solve for x.
3(3x - 1) + 2(3 - x) = 0

Weegy: 3(3x - 1) + 2(3 - x) = 0 ; 9x - 3 + 6 - 2x = 0 ; 7x +3 = 0 ; 7x = -3 ; x = -3/7. The answer is B. x = -3/7 debnjerry|Points 13661|

User: Solve for B.
R = x(A + B)

Weegy: 1/a+b+x=1/a+1/b+1/x
=>(1/a+b+x)-1/x=1/a+1/b
Taking (a+b+x)x as LCM,
=>x-(a+b+x)/(a+b+x)x=b+a/ab
=>-(a+b)/x2+ax+bx=a+b
Cancelling (a+b) from both sides we get,
=> -1/x2+ax+bx=1/ab
=> x2+ax+bx= -ab
=>x2+ax+bx+ab=0
=> x(x+a)+b(x+a)=0
=>x+b=0 [ or x+a=0
=>x=-b or x=-a ] shobhna|Points 80|

User: The first side of a triangle measures 5 in. less than the second side, the third side is 3 in. more than the first side, and the perimeter is 17 in. How long is the third side?
If s represents the length of the second side, which of the following represents the length of the third side?

Weegy: s-2 is the length of the third side. s=8 so the length of the third side is 6. Expert answered|sls23|Points 1172|

Weegy: True. During the change of state, the molecules of a substance absorb energy to overcome the strong intermolecular force of attraction between them. Hence the heat enegy which we supply is absorbed by them for this purpose. [ So change in temperature is not observed. ] (More)
