Answer:
Number of tadpoles Chris has = 3
Number of tadpoles David has = 6
Number of tadpoles George has = 12
Step-by-step explanation:
Given: Total number of tadpoles divided among 3 friends = 21
Number of tadpoles Mark gave to Chris = A
Number of tadpoles Mark gave to David = B = 2A
Number of tadpoles Mark gave to George = C = 2B = 2(2A) = 4A
∴ Total number of tadpoles = A + B + C
⇒ 21 = A + 2A + 4A
⇒ 21 = 7A
⇒ A = 21 ÷ 7 = 3
∴ Number of tadpoles Chris has = A = 3
Number of tadpoles David has = B = 2A = 2(3) = 6
Number of tadpoles George has = C = 2B = 2(2A) = 4A = 4(3) = 12
The answer is x1= 0, x2= 6

Answer:
The new pressure of the gas is 42 pounds per square inches.
Step-by-step explanation:
When the temperature remains constant, the volume of a gas is inversely proportional to the pressure of the gas.
We can rewrite the above equation is
[at constant temperature]
At a pressure of 14 pounds per square inches, a balloon is filled with 93 cubic inches of gas.
The volume of the gas is decreased to 31 cubic inches.
Here,
= 93 cubic inches, 
= 14 pounds per square inches,
=31 cubic inches, 
= ?
pounds per square inches
The new pressure of the gas is 42 pounds per square inches.
the answer to your question is x= -2
