Question

Aduna valorile m,n,p,q cunoscand: 1×m=n×8=p×10=67-3×a=40

Answer 1

Răspuns

Explicație pas cu pas:

1 × m = n × 8 = p × 10 = 67 - 3 × q = 40

1 × m = 40

m = 40

_________

n × 8 = 40

n = 40 : 8

n = 5

_________

p × 10 = 40

p = 40 : 10

p = 4

_________

67 - 3 × q = 40

3 × q = 67 - 40

3 × q = 27

q = 27 : 3

q = 9

____________

m + n + p + q = 40 + 5 + 4 + 9 = 58 →  suma numerelor
