Answer:


v=(10)/(72)

Explanation:

(3.6:2)v+10=9v+9

(3.6/2)v+10=9v+9

1.8v+10=9v+9

subtracting 1.8v from both sides we get

1.8v-1.8v+10=9v-1.8v+9

10=7.2v+9

subtracting 9 from both the sides we get

10-9=7.2v+9-9

1=7.2v

dividing both sides by 7.2 we get


(1)/(7.2)=(7.2v)/(7.2)


(1)/(7.2)=v

multiplying both numerator and denominator by 10


v=(10)/(72)=v

Hence this is our answer

______

Answer:

10/72

___________________

Explanation:

(3.6:2)v + 10 = 9v+9 ⇔ (1.8)v + 10 = 9v+9 ⇔ 10-9=9v-1.8v⇔ 1=7.2v ⇔ v=1/(7.2)

⇔ v=10/72 = 0,138888888889.
