Which equation shows the product 2.4 x 10? PLZ HELP :(

Elina [12.6K]

The Answer:

2.4x10=24

there is one 0 in 10, so you move the decimal over by 1, resulting in 2.4 turning into 24

If you have 5 math textbooks, how many different ways can you arrange them on your bookshelf?

alexdok [17]

Take all five books and name them from one to five. From there you can arrange them in any order until you no longer get a different set of numbers. Start with 12345 and go from there.

example: 12345, 15234, 14523,13452 and so on.

Find the constant of variation k for the direct variation. 2x + 6y = 0

Flauer [41]

Answer:

$k=-\frac{1}{3}$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem we have

$2x+6y=0$

Isolate the variable y

subtract 2x both sides

$2x+6y-2x=0-2x$

$6y=-2x$

Divide by 6 both sides

$y=-\frac{1}{3}x$

therefore

The constant of variation is equal to

$k=-\frac{1}{3}$
