Step-by-step explanation:
Answer:
a = 15
b = -10
Step-by-step explanation:
Here, we want to solve the system of linear equations
Firstly, let us multiply the first equation through by 10
2a - 5b = 100 ••••(i)
from the second equation;
a = 29 + b
Substitute this into i
2(29 + b) - 5b = 100
58 + 2b -5b = 100
-3b = 100-58
3b = 42
-b = 42/3
-b = 14
recall;
a - b = 29
a - (-14) = 29
a + 14 = 29
a = 29-14 = 15
Answer:
Step-by-step explanation:
ky-bf = fy/m
Ky - bf = fy/m
Multiply each term by m
Kym - bfm = fy
Collecting y
Kym - fy = bfm
y(km - f) = bfm
y = bfm/(km-f)

Step-by-step explanation:
Raghu investment = Rs 60,000
Nazar investment = Rs 100,000
Raghu profit = 1800
Nazar profit = 3000
Raghu invested Rs. 60000 and Nazar Rs. 100000. The ratio of their investments will be:
= 60000/100000
= 3/5
= 3:5.
The ratio of their profit will be:
= 1800/3000
= 3/5
= 3:5
Since we have identical ratio, we can then say that the investment and the profit are divided proportionally.
