Answer:
0.05x + 0.10y ≤ 1
Step-by-step explanation:
At a hardware store a bag holds upto 1 pounds of nails.
Each peny nails (x) weigh 0.05 pounds.
and wood nail (y) weigh 0.10 pounds
So total weight of penny nails and wood nails
= (0.05x + 0.10y)
This weight should be less than 1 pound bag.
So inequality formed will be 0.05x + 0.10y ≤ 1

Since slopes PQ & PR,
, it's a right triangle
The given equation is :
We need to find the value of x.
When the exponent 2 removes from LHS, it will shift to RHS as square root as follows :
We know that, 4×4= 16 and 5×5 = 25
So,
So, the solution of the given equation is 4/5.
