Respuesta :

1. k+5=11
2. 7n=42
3. l+13=17
4. 10- p²=9
5. x²+y²=4

Answer:

5+k = 11

Step-by-step explanation:

"Sum of a number" means addition.

"A number k and five" means you add the variable k and 5

"Is 11" tells you that the answer will be 11

You need to add K and 5 and get 11. Use this to set up an equation. Solve for K if need be. This results in k=6 but i believe that is not part of the prompt. Happy mathing ;)
