Don’t you just love inequalities? Of course I can only hear you saying “not really…inequalities stink!” Well I know you may not like inequalities but you need to know how to work with them. All right let me stress some points:
* the solution to an inequality is more than a single number; inequalities have solution sets (many/infinite number of solutions). As an example lets consider the inequality x > 5 what can the value of x be? i.e. what numbers are greater than 5? clearly an infinite amount of numbers are greater than 5 so we need to express the solutions to inequalities in a different way other than writing out all the numbers greater than 5 – that would take a lot of paper and with global warming….you get the idea. So to deal with this little issue we graph the solution of an inequality on a number line.
other important points:
* we simplify inequalities using the same steps as solving equations
* when dividing/multiplying both sides of an inequality by a negative number you need to reverse the inequality symbol; example > would turn into < .
* when graphing your solution <, > symbols use open circles; <=, >= symbols fill in the circle.
* make sure you can solve linear equations before taking on inequalities- good luck and may the force be with you!!
It would be 10/9
Use the keep, change, flip rule to solve
5*2=10 which will be in top
And 9*1=9 which will be at the bottom
Im just gonna assume you mean from longest to shortest length? wouldn't it be 3/8 3/6 3/4?
Answer: 3(x minus 5.50) = 111.75; the monthly Internet service is $42.75
Step-by-step explanation:
Given the following :
Total amount spent on internet for 3 months = $111.75
Monthly credit received on bill = $5.50
Monthly Credit of $5.50 means $5.50 is deducted from the amount being paid on thir bill monthly.
Assume their monthly internet service fee = x
The amount paid before the credit deduction each month:
Amount paid - credit
(x - $5.50)
For 3 months :
3 × (x - $5.50) = $117.75
3(x - $5.50) = $117.75
Monthly fee paid before credit deduction:
3(x - $5.50) = $117.75
3x - $16.50 = $117.75
3x = $117.75 + $16.50
3x = $128.25
x = $128.25 / 3
x = $42.75
Answer:
A: 4/8
Step-by-step explanation:
1/2 is the same as 4/8 because if we divide 4 to both the numerator (4 divided by 4) and the denominator (8 divided by 2), we get 1 for the numerator and 2 for the denominator.
