Question

calculati suma n+p stiind ca: mn+mp=147 si m =7
b)mn+mp=265 si m =5
c) mn +mp=364 si m=13
d)mn+mp=405 si m=15

Answer 1

mn + mp = 147   si  m = 7

m ( n + p ) = 147

7 × ( n + p ) = 147

n + p = 147 : 7

n + p = 21

____________________

b)   mn + mp = 265   si m = 5

m × ( n + p ) = 265

5 × ( n + p ) = 265

n + p = 265 : 5

n + p = 53

_______________________

c)   mn + mp = 364  si m = 13

m × ( n + p ) = 364

13 × ( n + p ) = 364

n + p = 364 : 13

n + p = 28

d)  mn + mp = 405   si  m = 15

m × ( n + p ) = 405

n + p = 405 : 15

n + p = 27
