Answer:
Step-by-step explanation:
move all the terms to the right so your equation will equal 0. then look for the common denominator. which in this case is 60 (5*4*3).
multiply all terms by 60 then simplify.
12(2x-3)-15(6-3x)+120-20(7x)=0
24x-36-90+45x+120-140x=0
combine like terms and then divide
-71x=6
x=-6/71
(do not forget parenthesis when simplifying they are very important when it comes to distributing the minus sign)
The answer would be 3:33333
Answer:
25
Step-by-step explanation:
8b^2 +2a(4c-b)
Let a = 1/4 b=2 c= -3
8 ( 2)^2 +2(1/4) ( 4*-3 -2)
Parentheses first
8 ( 2)^2 +2(1/4) ( -12 -2)
8 ( 2)^2 +2(1/4) ( -14)
Then exponents
8 ( 4) +2(1/4) ( -14)
Then multiply
32 -7
Subtract
25
