Question

determina valoarea fiecarei litere stind ca a×b=90 ,b=c×3 ,c=d÷10 ,d-e=250 ,e÷10=5

Answer 1

a×b = 90
b = c×3
c = d:10
d - e = 250
e : 10 = 5 =>e = 5×10 = 50
inlocuim pe e cu 50 in ec. d-e = 250
d-50 = 250
d = 250+50
d = 300
c = d:10 = 300:10 = 30
b = c×3 = 30×3 = 90
a×b = 90 => a = 90:b = 90:90 = 1

a = 1
b = 90
c = 30
d = 300
e = 50

Answer 2

a×b=90
b=c×3
c=d:10
d-e=250
e:10=5



e:10=5
e=10×5
e=50


d-50=250
d=250+50
d=300


c=300:10
c=30

b=30×3
b=90

a×90=90
a=90:90
a=1




RĂSPUNS :
a-----> 1
b------>90
c--------->30
d-------->300
e--------->50




VERIFICARE :
1×90=90
90=30×3
30=300:10
300-50=250
50:10=5
