Shannon bought 2 necklaces at $15.00 each. She received a third necklace at half-price. How much did Shannon spend?

$37.50

Step-by-step explanation:

2 necklaces for $15.00 = $30.00

Plus the $7.50  for the third necklace ($7.50 is half of $15 which is what each necklace costs)

Add it all together:

$30 + $7.50 = $37.50

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 )

probably .5
