What is the algebraic expression of the problem one-fifth of the sum of the number ( u is the number in this case) and two

Answer 1

You are asked to find an algebraic expression. That means there will not be an equal sign.

The sum of two numbers means add them together.

One of the numbers is represented by u and the other is 2.

So the sum is represented by u + 2.

Now we want one-fifth of that sum, which means multiply by 1/5.

1/5 (u + 2)

If you were told that the result of that operation was 20 (for example), then you could write an equation and solve for u.

1/5 (u + 2) = 20

u+2 = 100 (multiply both sides by 5)

u = 98
