evaluate the following expression 5c-2k when c=7 and k=3
7
29
3
34
To evaluate the expression 5c-2k when c=7 and k=3, substitute the given values into the expression:
5(7) - 2(3)
Simplifying the expression:
35 - 6 = 29
Thus, the evaluated expression is 29.
To evaluate the expression 5c - 2k when c = 7 and k = 3, substitute the values of c and k into the expression.
Therefore, the expression becomes:
5(7) - 2(3)
Simplifying the expression further:
35 - 6
This gives a final result of:
29
So, when c = 7 and k = 3, the value of the expression 5c - 2k is equal to 29.
To evaluate the expression 5c - 2k when c = 7 and k = 3, you need to substitute the given values of c and k into the expression and perform the arithmetic operations.
First, replace c with 7 and k with 3 in the expression:
5c - 2k = 5(7) - 2(3)
Next, multiply the numbers inside the parentheses:
5(7) = 35
2(3) = 6
Now, substitute the calculated values into the expression:
5c - 2k = 35 - 6
Finally, perform the subtraction:
35 - 6 = 29
Therefore, when c = 7 and k = 3, the value of the expression 5c - 2k is 29.
