Consider the algebraic expression 5

(Evaluate the expression when a = 2.5. show your work)

I NEED HELP, school is over next week and these are for my test corrections, Please help.

P.s I don't know if the question made sense but that's how it was written for me, lol.

Check how your post is displayed.

All I see of your "expression" is a 5

Just type normally on your keyboard, use * for multiplication,
/ for division and x^2 or terms like "x squared"

(I mean consider the algebraic expression 50+2a)

Ok

50+2a
= 50 + 2*2.5
= 50 + 5
= ....

To evaluate the algebraic expression 5 when a = 2.5, you simply substitute the value of a into the expression and perform the necessary calculations.

Step 1: Replace the variable a with the given value of 2.5 in the expression 5.
5

Step 2: No further simplification is needed since there are no other variables or operations involved. Therefore, the final answer is:
5

So, when a = 2.5, the value of the algebraic expression 5 is also 5.
