What is the algebraic expression of a number decreased by the sum of the number and one?

x-(x+1)

Step-by-step explanation:

The number is our unknown here, so we'll use the variable x to represent it in the equation. Now, a key phrase here is "decreased by"; that's telling us to subtract whatever comes next, which in this case, is the sum of x and 1. Since we're instructed to subtract the sum of these numbers together, we want to go ahead and put x+1 in parentheses. Now we've got the basic elements of the equation figured out, we only have to put it all together! And that gives us x, which is the number, minus (x+1), which is the sum of that number and 1.

the answer is 175.4379

step-by-step explanation:

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !
