Answer:
25
Step-by-step explanation:
Since y varies inversely with x, the relation between y and x will be:

Introducing the proportionality constant, we can write:

Using the first set of given values of x and y, we get:

This means, the relation between y and x is:

We have to find y if x = 20. Using this value in above equation, we get:

Thus y would be 25 if x is 20.
Answer:
$37.05
Step-by-step explanation:
If you take 15% and 20% you get (15%+20%) which is 35%, then you take 100%-35% you get 65%, 65% of 57 is 37.05.
Thus Your Answer: $37.05
Answer:
12
Step-by-step explanation:
A² + B² = C²
9² + B² = 15²
81 + B² = 225
B² = 144
B = 12
2x-3yi=14+12i
=> 2x=14; -3yi=12i => x=7; y=-4
Answer:
71 baskets of 3 apples.
Step-by-step explanation:
From each of the 28 baskets of 6 you can get 6/3 = 2 baskets of 3.
From each of the 5 baskets you can get 9/3 = 3 baskets of 3.
Therefore:-
From the 28 baskets you can create 28 * 2 = 56 baskets of 3.
From the 5 baskets of 9 you can get 5 * 3 = 15 baskets of 3.
Total 15 + 56 = 71.
