Anumber, half of that number, and 1/5 of that number added. result is 51. what is the original number?

30

Step-by-step explanation:

let the original number be x then

x + x + x = 51

multiply through by the lowest common multiple of 2 and 5, that is 10, to eliminate the fractions

10x + 5x + 2x = 510

17x = 510 ( divide both sides by 17 )

x = 30

Thus the original number is 30

dont think so

step-by-step explanation:

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !
