A cellar contains only bottles of port, claret, sherry and brandy. Of these, 1/5 of the bottles are port and 1/5 are claret. The cellar also contains 15 dozen bottles of sherry and 30 bottles of brandy. How many bottles of port and claret does it contain?

70 bottles of each

Step-by-step explanation:

let X be bottles of port and claret

X = 2/5

1/2 X = 1/5

180 + 30 = 210 = 3/5

210/3 = 70 = 1/5

70 x 2 = X = 140

2/5 = 140

1/5 = 70

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y
