Question

Evaluate the algebraic expression when x=10x/2 + 5

A. 5/2
B. 10
C. 5
D. 2/5

Answer 1

To evaluate the algebraic expression when x=10x/2 + 5A, substitute the value of x=10 into the expression and simplify to find the value of A.

Step-by-step explanation:

To evaluate the algebraic expression when x=10x/2 + 5A, we need to substitute the value of x into the expression and simplify.

Substituting x=10, we have:

10 = 10(10)/2 + 5A

Simplifying further:

10 = 100/2 + 5A

10 = 50 + 5A

Now, rearrange the equation:

10 - 50 = 5A

-40 = 5A

Finally, solve for A:

A = -40/5

A = -8

Therefore, when x=10, the value of A in the expression is -8.
