When a decimal is written in word form, what indicates whether the number can be written as a mixed number or as a fraction less

vekshin1

9514 1404 393

Answer:

"and"

Step-by-step explanation:

Properly written, the word "and" separates the integer portion from the fractional portion of the number. If there is no "and", then there is no integer portion, so the number is a fraction less than 1.

<u>Examples</u>:

one <em>and</em> three tenths = 1 3/10

thirty-one thousandths = 31/1000

Solve the equation <br> (If possible please show work)

deff fn [24]

Answer:

$x=-3$

Step-by-step explanation:

So we have the equation:

$-2(-x-4)+3=-7-4x$

First, distribute the left side:

$-2(-x)-2(-4)+3=-7-4x\\2x+8+3=-7-4x$

Add values on the left side:

$2x+11=-7-4x$

Add 7 to both sides. The right side cancels:

$(2x+11)+7=(-7-4x)+7\\2x+18=-4x$

Subtract 2x from both sides. The left side cancels:

$(2x+18)-2x=(-4x)-2x\\18=-6x$

Divide both sides by -6:

$(-6x)/-6=18/-6\\x=-3$

Therefore, x equals -3.
