In here, we will use the distance formula

Compute the distance between <span>(-5, 3) and (5, 3)
</span>

<span>
= 10
The distance between </span>(-5, 3) and (5, 3) is 10
Let's represent this unknown number with the variable 'n'
n + n + 2n + 4n = -104
Explanations:
'n+n' - a number plus itself
'+2n' - plus twice itself
'+4n' - plus 4 times itself
Anyway:
n + n + 2n + 4n = -104
Simplify:
8n = -104
Divide both sides by 8:
n = -13
The number is -13
Good luck! If you need me to explain something in more depth, just ask :))

Answer:
31 and 13
Step-by-step explanation:
31+13=44 and 13+18=31 so they are 18 apart
A) 5n- 1
the patterns going up in 5s and to get back to 4 you need to - 1
$25 x 14 (students)= $350
$350 - $84.14= $265.86
$265.86 divided by 14 (students)= $18.99
Answer: $18.99
