It's not -33What is the value of x in the equation?

Two-thirds (x + 6) = negative 18
–36
–33
–24
--18

Answers

Answer:

x = -33

Step-by-step explanation:

It is required to find the value of x in the following equation ::

Two-thirds (x + 6) = negative 18

It means,

(2)/(3)(x+6)=-18

We need to simplify the above equation

(x+6)=(-18* 3)/(2)\n\nx+6=-27

Subtracting 6 on both sides of the equation,

x+6-6=-27-6\n\nx=-33

So, the value of x is (-33).

Neal buys a board game. He pays for the board game andpays $1.54 in sales tax. The sales tax rate is 5.5%.
What is the original price of the board game, before tax?

Answers

Answer:

$27.99

Step-by-step explanation:

100/7.25% sales tax = 1.54 x 13.7931034483 = 21.2413793104

We did the example to prove that when accounting for fixed tax the price will be higher once tax of same percentage amount applied.

This proves 1.75% more in interest is a far lower price ($6.56 less)

Where we compare the price set for 5.5 as asked in the question.

100/5.5% sales tax = 1.54 x 18.181818181 =27.9999999987

=$27.99
