30 !
to convert measurements in the metric system, you can move the decimal point left or right. why does this work? the metric system only uses decimal numbers. converting in the metric system does not involve multiplication or division. the metric system is based on powers of 10. the metric system does not have conversion factors.

This works because the metric system is based on powers of 10.

Step-by-step explanation:

since it's based on 10 it allows you to move the decimal to the left or right because each time you move it it goes up 10 or down ten depending on which way you move it. Each time you move a decimal it goes 10 either way.

:) hoped this helped

Please give me the brainliest answer

This works because the metric system is based on power of 10.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

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.
