Hope this answers your question!
Don't forget the invisble negative ones to distriute
do inside to outside
{n-1-1[n-1-1(n-1)]}
do inside
{n-1-1[n-1-n+1]}
simplify inner parenthasees
{n-1-1[n-n+1-1]}
{n-1-1[0]}
multply
{n-1-0}
add
n-1-0=n-1
it is n-1 simplified
Put 10 where n is, then do the arithmetic.
... the cost for 10 people equals 100 + 4·10 = 100 + 40 = 140 . . . . dollars
Answer:
The correct choice is <u><em>option A. 2 < x < 10/3</em></u>
Step-by-step explanation:
|3x - 8| < 2
= -2 < |3x - 8| < 2
3x - 8 > -2 and 3x - 8 < 2
+8 +8 +8 +8
----------------- ------------------
3x > 6 3x < 10
/3 /3 /3 /3
----------------- -------------------
x > 2 x < 10/3
= 2 < x < 10/3
