Bweighs 2/3 of what d weighs. if d weighs 72 pounds how much does b weigh

48 lb.

Step-by-step explanation:

Translate this word problem into algebraic equations:  B = (2/3)D and D= 72 lb.

Substituting 72 lb for D in the first equation, we get B = (2/3)(72 lb) = 48 lb.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
