Because the "sum" of two or more numbers means the answer when the numbers are added together, your answer is simply: 11+k
Unless k was assigned a value in the problem, this is your final answer. Because 11 and k aren't like terms (they don't have the same variable attached), you cannot add them together.
15-k
k-2.5 An algebraic expression is just using variables (in this case, k) for unknown numbers. Since the question is asking what the number k minus 2.5 is, your answer is k-2.5.
It is: 7k
The algebraic expression is 6x+k
the + of a number and 10 k decreased by 4 = k-4
(100)/(k+m)
15-k
Algebraic expression 14 less than the quantity k times 6
k - 6
k-2.5 An algebraic expression is just using variables (in this case, k) for unknown numbers. Since the question is asking what the number k minus 2.5 is, your answer is k-2.5.
It is: 7k
k > 10
The algebraic expression is 6x+k
the + of a number and 10 k decreased by 4 = k-4
As an algebraic expression it is: k-3
(2/3)k
k added to 2.5
