Alright
so
28% of 2 m³=0.28 times 2=0.56 m³ of silt in the first mixture
13% of the 1 m³=0.13 times 1=0.13 m³ of silt in 2nd
total is 0.56 m³+0.13 m³=0.69 m³ of silt
and the total is 2m³+1m³=3m³
so
0.69/3=0.23=23%
answer is D
It is the last equation. You square both sides.
6x + 7y = 59...multiply by -4
4x + 5y = 41...multiply by 6
Answer:
Option c) is correct.
The value of y in the given equation is 26 ie., y=26
Step-by-step explanation:
Given equation is

Now to the find the value of y in the above equation.
To find y simplify the above equation


Now apply distributive property



Therefore y=26
