2x + 4y = 8
<u>-2x -2x</u>
<u>4y = 8 - 2x</u>
4
y = 2/1 - 1/2x
* plung in y*
2x + 4 (2/1 - 1/2x) = 8
2x + 8 - 2x = 2
(2x - 2x = x cancle out)
8 = 2

Step-by-step explanation:
1. Approanch
An easy way to calculate one's salary after they recive a raise is to, convert the percent that one's salary is increased into a decimal; divide the percent by 100. Then multiply the increase as a decimal by the original salary, to attain the amount the salary is raised by. Finally add the amount the salary is raised by to the original salary to find the new salary. A quicker way to do this is to convert the percent by the salary is increased into a decimal. Then add 1 to that number. Finally one will multiply that number by the original slary and get the new salary.
2. Solving
Original salary; 1500
Raise; 20%
<u>a. convert the raise as a percent into a decimal, then add 1</u>
20% = 0.2
0.2 + 1 = 1.2
<u>b. multiply the number by the original salary</u>
1.2 * 1500
1800
Number 7 is 16 and #6 is 29
and 8 is 45
Answer:
Yes I can :O
Mean: About 11.87
Median: 11
Mode: 10
Step-by-step explanation:
Mean: Add up all the numbers and divide by the total number of numbers
<em>*deep breath in haha*</em>
6+7+7+8+8+9+9+9+50 (the 10s)+33 (the 11s)+12+12+12+12+13+14+14+16+16+17+17+18+18+19=356
356 (total) / 30 (number of numbers) = 11.8666666666666666666666 etc = 11.87
Median: With all the numbers in order, the middle number (if there are two add them together and divide by 2)
Not much to show, just mark them off starting from the outside getting inside, you end up with 11!
- See attached
Mode: Data value that occurs most often, in this case we can see that 10 happened the most
Hope this helps, have a nice day! :D
