Subtract 2W from both sides
2L = P - 2W
divide both sides by 2
L = P/2 - W
6+12= 18
6+6+6=18
18-4=14
Explanation:
Before he was 6.
So 6+12 would give us 18 which will be his age after 12 years.
and 3 times 6 equals 18
we want to know what the current age was so
we subtract 18 - 4 which is equal to 14
Answer:
is that thing a less than sign?
Step-by-step explanation:
Answer:
The number of problems solved = 2000
Step-by-step explanation:
Let us assume the monthly quota of problems be x
number of problem solved in first week = 25 % of x =![0.25x](https://tex.z-dn.net/?f=0.25x)
number of problems solved in 2nd week = 110% of (problems solved in 1st week)
= ![1.10 (0.25x)](https://tex.z-dn.net/?f=1.10%20%280.25x%29)
=![0.275x](https://tex.z-dn.net/?f=0.275x)
number of problem solved 3rd week= 60% of ( problems solved in 1st and 2nd week)
= ![0.60(0.25x+0.275x)](https://tex.z-dn.net/?f=0.60%280.25x%2B0.275x%29)
=![0.60(0.525x)](https://tex.z-dn.net/?f=0.60%280.525x%29)
=![0.315x](https://tex.z-dn.net/?f=0.315x)
number of problem solved in 4th week = ![320](https://tex.z-dn.net/?f=320)
now we have
number of problems solved in ll 4 weeks = x
![0.25x +0.275x+0.315x+320=x](https://tex.z-dn.net/?f=0.25x%20%2B0.275x%2B0.315x%2B320%3Dx)
![0.84x+320=x](https://tex.z-dn.net/?f=0.84x%2B320%3Dx)
![320=x-0.84x](https://tex.z-dn.net/?f=320%3Dx-0.84x)
![320=0.16 x](https://tex.z-dn.net/?f=320%3D0.16%20x)
![x=\frac{320}{0.16}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B320%7D%7B0.16%7D)
![x=2000](https://tex.z-dn.net/?f=x%3D2000)
Hence the number of problems solved = 2000
The answer will be 39 because it's the half of it
