What is inequality?
Inequality is a relation that makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size.
\(8x+2 < 6x-9\)
Subtract 2 from both sides
\(8x+2-2 < 6x-9-2\)
Simplify
\(8x < 6x-11\)
subtract
\(8x-6x < 6x-11-6x\)
Simplify
\(2x < -11\)
divide 3 both sides by 2
x=-11/2

Anna enjoys dinner at a restaurant in Washington D.C, where the sales tax on meals is 10%. She leaves a 15% tip on the price of her meal before the sales tax is added, and the tax calculated is on the pre-tip. She spends a total $27.50 for dinner. What is the cost of her dinner without tax or tip?
Answers
Answer: $20.62
Step-by-step explanation:
Ok so she spent 27.50 and the tax was 10% and the tip was 15%
10% of 27.50=0.1*27.50=2.75
15% of 27.50=0.15*27.50=4.125=4.13 (rounded to the nearest cent)
So the question is asking about without the tax (2.75) or the tip (4.13) so you have to subtract the tax and tip from the total cost (27.50)
27.50-2.75-4.13=20.62
The cost of her dinner without tax or tip is 20.62
Answer:$20.62 would be the price

An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $3800 and his stock in Company B was worth $3400. The stock in Company A has decreased 22% since last year and the stock in Company B has decreased 12%. What was the total percentage decrease in the investor's stock account? Round your answer to the nearest tenth (if necessary).
Answers
Answer: The total percentage decrease in the investor's stock account is 34%
Step-by-step explanation:
The investor's stock in Company A= $3800
The investor's stock in Company B= $3400
Percentage decline in stock of company A= 22%
Decline in value of stock of company A= 3800× 22/100
= 38×22
= $836
Percentage decline in stock of company B= 3400×12/100
= 34×12
=$408
Total decline in wealth of investor= 836+ 408
= $1244
Total percentage decline in wealth= 1244×100/7200
= 124400/7200
= 17.27%
The percentage decrease in investor's stock is 17.27%

Josh is 72 inches tall. Ruben is 9/10 as tall as josh. John is 11/12 tall as ruben. a. what is rubens height in inches b. what fractional of of joshs height is johns?
Answers
Answer:
A. Ruben's height- 64.8 inches
B. John's height- 3/4 of Josh's height
Step-by-step explanation:
A. Since Ruben's height is 9/10ths of Josh's, and Josh's is 72 inches, we can find 90% of Josh's height which is 72, therefore giving us 64.8 inches.
B. Now take John's height of being 11/12th as being tall as Ruben, we can enter 11/12th of 64.8 which would give us about 54 inches. Finally, taking John's height of 54 inches, we would divide it with Josh's height of 72 inches. Hence, 54/72=3/4 as a fraction.
B. 33/40 is the fractional part of johns height to Josh’s
