Step-by-step explanation:
Let the total amount of salary be X, then
3/10X + 2/3X + amount left= his salary(X)
(9X + 20X)/ 30 + 2100 = X
29X/30 - X = -2100
(29X - 30X)/30 = -2100
by cross multiplying
-X = -2100×39
-X = -81900
divide both side by -1
X = 81900.
therefore his salary = 81900
Answer:

Step-by-step explanation:
Since they are simliar, they are proportional.
SO, you can do AC/XZ = BC/YZ
You can also see that XZ is 5 times larger than AC
SO multiply BC by 5.
Answer:
2.1 x 10^5 = 210,000.
Step-by-step explanation:
Convert 2.1 x 10^5 to ordinary form
10^5 = 100000
2.1 = 21/10
Thus.
2.1 x 10^5 = 21/10 * 100000 = 210,000
Ordinary form of 2.1 x 10^5 is 210,000.
