.
Step-by-step explanation:
Given:
We need to reduce
by 
Solution:
To reduce the equation means we need to subtract the one equation from other.
First we will arrange the equation n proper format we get;
⇒ equation 1
Also Arranging other equation we get;
⇒ equation 2
Now we will subtract equation 2 from equation 1 we get;

Now Applying distributive property for the sign we get;

Now Arranging the like terms we get;

Hence the reduce form of the given equation is
.
Answer:
24 hours
Step-by-step explanation:
4 people can do the work in 6 hours
4*6 = 24 work hours
It will take 1 person 24 work hours to complete the job
2(2x +2y) and <span>√(4x + 4y)^2</span>
380 - 18% of 380
= 380 - (18/100)×380
= 380 - 68.4
= 311.6
