Answer:
7-(-4)= Positive
-3+(-2)= Negative
5-8= Negative
-10 +12= Positive
Step-by-step explanation:
The solution of inequality 
is f < 132
<em><u>Solution:</u></em>
Given that we have to find the solution of inequality
These things do not affect the direction of the inequality:
Add (or subtract) a number from both sides.
Multiply (or divide) both sides by a positive number.
Simplify the sides
<em><u>Given inequality is:</u></em>
Add 19 to both sides of equation
Multiply both the sides of inequality by 2
Thus the solution to given inequality is f < 132
You want to leave a 15% tip on a meal that cost $65.00.
First, convert the 15% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.
Second, you need to find out what 15% of your $65.00 meal cost is.This is always done by multiplying 0.15 by $65.00, or
0.15 x $65.00=$9.75.
So, the amount of tip you are going to leave is $9.75.
This makes the total cost of your meal (to write on your charge slip or other payment)
$65.00 + $9.75 = $74.75.
The sum of a rational number and an irrational number is irrational." By definition, an irrational number in decimal form goes on forever without repeating (a non-repeating, non-terminating decimal). By definition, a rational number in decimal form either terminates or repeats.
