Answer:
x = 66
Step-by-step explanation:
The similarity ratio is DO/PA = 27/18 ➡3/2
So DT/PN ➡ x/44 = 3/2
132 = 2x divide both sides by 2
x = 66
Answer:
a. 7 times
b. 74.7 km
Step-by-step explanation:
a. From Albany to Pittsburgh, there are 739.7 km.
She stopped to rest after every 95 kilometres:
Therefore, let us find how many times she stopped:
739.7 / 95 = 7.79
We only need the quotient, that is, 7
So she stopped 7 times.
b. After her last stop, she had traveled:
7 * 95 = 665 km
Therefore, the distance she has left after her last stop is:
739.7 - 665 = 74.7 km

Answer:
15 business class and 12 economy class
Step-by-step explanation:
Let the x be the number of business class. y be the number of economy
x + y = 27 ...............(a)
700x + 375y = 15000 .............(b)
Multiply first equation by 700
700*x + 700*y = 700*27
700x + 700y = 18900 ...............(c)
Recall:
700x + 375y = 15000 .............(b)
-
700x + 700y = 18900 ...............(c)
____________________________
0 -325y = -3900
y = -3900/-325 = 12
Recall x + y = 27, x + 12 = 27, x = 27 - 12 = 15
the answer is 15 business class and 12 economy class
