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:

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

HELP PLZ AND EXPLAIN

Marat540 [252]

Hey there! :D

Find 10% of 85.

10%=.10

85*.10= 8.5

Add that to 85.

85+8.5= 93.5

We could also see if this 10% error is in the other direction.

85-8.5= 76.5 <== this is not an answer choice

So, we know it must be "A" 93.5 C

I hope this helps!
