Question

nu vreau doar raspunsul vreau si rezolvarea dau coroana

Answer 1

a) n/12=5/6
6 N=60
n=60:6=30
b)35/n=5/6
210=5 n
n=210:5=42
c)( n+1)/18=5/6
6( n+1)=90
n+1=90:6=15
n=15-1=14
d)30/(2 n+4)=5/6
5( 2 n+4)=180
2 n+4=180:5=36
2 n=36-4=32
n=32:2=16
e)105/(10 n+6)=5/6
5(10 n+6)=630
10 n+6=630:5=116
n=110:10=11
f)55/ n+2=5/6
5( n+2)=330
n+2=330:5=66
n=66-2=64
g)50/ n-14=5/6
5( n-14)=300
n-14=300:5=60
n=60+14=74
h)15/ n+7=5/6
5( n+7)=90
n+7=90:5=18
n=18-7=11
i) n-23/18=5/6
6( n-23)=90
n-23=90:6=15
n=15+23=38
j)25/ n•( n+1)=5/6
5[ n• ( n+1)]=150
n•( n+1)=150:5=30
n²+ n=30
