Question

Calculati suma n+p,stiind ca : a) mn+mp=147si m=7. b) mn+mp=265 si m=5. c)mn+mp=365 si m=13. d)mn+mp=405 si m =15. Urgent !!!!!!!

Answer 1

Răspuns:

Explicație pas cu pas:

mn+mp=147

mx(n+p)=147

7x(n+p)=147

n+p=147:7

n+p=21

mn+mp=265

mx(n+p)=265

5x(n+p)=265

n+p=265:5

n+p=53

mn+mp=365

mx(n+p)=365

13x(n+p)=365

n+p=365:13

n+p=28,(076923)

mn+mp=405

mx(n+p)=405

15x(n+p)=405

n+p=405:15

n+p=27
