Answer :
Good morning ☕️
______
Answer:
10/72
___________________
Step-by-step 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.

Answer:
[tex]v=\frac{10}{72}[/tex]
Step-by-step 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
[tex]\frac{1}{7.2}=\frac{7.2v}{7.2}[/tex]
[tex]\frac{1}{7.2}=v[/tex]
multiplying both numerator and denominator by 10
[tex]v=\frac{10}{72}=v[/tex]
Hence this is our answer
