Answer:
Infinite solutions.
Step-by-step explanation:
If an equation is an identity, then there will be infinite solutions that the identity will have.
Let, us assume that an identity equation is given by
(a + b)² = a² +2ab + b².......... (1)
Now, putting any real values of a and b the identity will be satisfied.
Therefore, there are infinite solutions for an identity equation. (Answer)
Given:
A solution of 60% fertilizer is to be mixed with a solution of 21% fertilizer to form 234 liters of a 43% solution.
To find:
The quantity of the 60% solution in the mixture.
Solution:
Let x be the quantity of the 60% solution and y be the quantity of the 21% solution.
Quantity of mixture is 234. So,

...(i)
The mixture has 43% fertilizer. So,

Multiply both sides by 100.
...(ii)
Using (i) and (ii), we get




Divide both sides by -39.


Putting this value in (i), we get


Therefore, 132 liters of the 60% solution must be used.
Answer: He should have translated the scenario as value of all dimes = value of all
Step-by-step explanation:
use this equation to solve for the surface area.
A=2(w+l+hl +hw)
w stands for width
l stands for length
h stands for height
That should be the equation there looking for (10x.20)h+.50
