First move the (Y) to the other side of the equal sign,
Then subtract add (15) on both sides
Since a variable can't be negative just divide by (-1) on both sides,
The answer would be,
Hope this helped

Answer:
16
Step-by-step explanation:
Put the numbers where the variables are and evaluate:
F(3) = 2(3)^2 +1 = 19
G(4) = 2(4) -1 = 7
H(5) = 5
Then the desired sum is ...
F(3) +G(4) -2H(5) = 19 +7 -2(5) = 16
Gravity always acts downward on every object on earth. Gravity multiplied by the object's mass produces a force called weight. Although the force of an object's weight acts downward on every particle of the object, it is usually considered to act as a single force through its balance point, or center of gravity.
I think it would be 2 and a half hours/ 2 hours and 30 minutes.
