A number plus itself, plus twice itself, plus 4 times itself is equal to -104

NARA [144]

The scenario will will be represented by: $x+x+2x+4x=-104$

The number will be -13

Step-by-step explanation:

We have to convert the given situation into the mathematical form

Let x be the number

Then

"a number plus itself"

x+x

"plus twice itself"

x+x+2x

"plus 4 times itself"

x+x+2x+4x

"is equal to -104"

$x+x+2x+4x=-104$

This can also be written as:

$x+x+2x+4x=-104\\8x=-104\\Dividing\ both\ sides\ by\ 8\\\frac{8x}{8}=\frac{-104}{8}\\x=-13$

1000 mg = 1 g
the prefix "milli" means "thousandth", which is why there are 1000 mg in one gram

Use that equation above as the conversion factor
3500 mg = (3500 mg)*(1 g/1000 mg) = (3500/1000) g = 3.5 g

So in short,
3500 mg = 3.5 g

Answer: 3.5
