Răspuns :
a/b = 5
a-b = 32
a = 5 * b
5 * b - b = 32
4 * b = 32
b = 8
a = 40
a+b/2 = 48 /2 = 24
a-b = 32
a = 5 * b
5 * b - b = 32
4 * b = 32
b = 8
a = 40
a+b/2 = 48 /2 = 24
a)
• a÷b=5→a=b×5
• a-b=32→a=b+32
_______________
? a,b
_______________
a: |------|------|------|------|------|
b: |------| 32
4 p.e=32
1 p.e=32÷4
1 p.e=8 (b)
8×5=40 (a)
Verificare:
40÷8=5 (A)
40-8=32 (A)
Răspuns:
a=40
b=8
b)
(40+8)÷2=48÷2=24 (media aritmetică)
Succes !
