evalutate the expression at specific values of their variables

Question

evaluate cd-d+2e+10, when c=5, d=3, and e=9

Answer 1

To evaluate the expression "cd-d+2e+10" when c=5, d=3, and e=9, substitute the given values into the expression:

Replace c with 5:
5 * d - d + 2e + 10

Replace d with 3:
5 * 3 - 3 + 2e + 10

Replace e with 9:
5 * 3 - 3 + 2 * 9 + 10

Multiply 5 and 3:
15 - 3 + 2 * 9 + 10

Multiply 2 and 9:
15 - 3 + 18 + 10

Perform addition and subtraction:
30 + 18 - 3 -10

48 - 3 - 10

45 - 10

= 35

Therefore, when c=5, d=3, and e=9, the expression "cd-d+2e+10" evaluates to 35.
