Answer:

x = -57/14, y = -6/7

Step-by-step explanation:

2x + y = -9

-(2x - 5y = -3)

--------------------   (Add the two equations together)

7y = -6

y = -6/7

2x - 6/7 = -9

2x = -57/7

x = -57/14

The Cutty Sark is a famous clipper ship (look it up)! A Cutty Sark model kit advertises a scale ratio of 1: 78, a length of 45 i
lukranit [14]

Answer: If the ratio is 1:78, a) the Cutty Sark is 3510 inches long or 292.5 ft; b) the Cutty Sark is 2028 inches tall or 169 ft according to this model

Step-by-step explanation: The ratio indicates that for every inch of the model, it corresponds to 78 inches of the actual size. If the length is 45 inches for the model, it would be an equivalent of 45*78 of the actual size = 3510 inches. The same can be applied to the height. Multiplying 26 x 78, the actual size should have a height of 2028 inches.
