Answer 2

VI.3.167 :

p=3r
g=p-r => g=3r-r => g=2r
v=r:2 => r=2v
g-v=36 => g=v+36
______________________
g=2r ; g=v+36
2r=v+36
r=2v |×2
_______________________
2r=v+36 ; 2r=4v
v+36=4v
4v-v=36
3v=36
v=36:3
v=12
_______________________
r=12×2
r=24
________________________
p=3×24
p=72
________________________
g=12+36
g=48

12+24+72+48=156 baloane


VI.3.166 :

a=b-26
b=(c+d)-205
c=d+148
d=24+(32×2)
_____________
d=24+64
d=88
_____________
c=88+148
c=236
______________
b=(236+88)-205
b=324-205
b=119
________________
a=119-26
a=93
________________
88+236+119+93=536


VI.3.168 :

Al-3=An-5=Ar-7
Al+3+An+5+Ar+7=45 prăjituri
Al+An+Ar=45-(3+5+7)
Al+An+Ar=45-15
Al+An+Ar=30
Acum ei sunt egali :
30:3=10 prăjituri
Al=10+3=13
An=10+5=15
Ar=10+7=17


VI.3.169 :

b mari-b mici=42 lei
b mari = 9 lei
b mici = 3 lei
_______________
9y-3y=42 lei
6y=42 lei
y=42:6
y=7 borcane
________________
100-(9×7+3×7)=
100-(63+21)=
100-84=26 lei rest


VI.3.170 :

1 dovleac = 4 verze
1 varză = 4 gutui |×4
→1 dovleac=4 verze=16 gutui |×2
→2 dovleci=8 verze=32 gutui
1 gutuie=2 mere |×32
→2 dovleci=32 gutui=64 mere
Răspuns:c)64 mere
