Step-by-step explanation:
[tex] \frac{v}{7} = 3 \\ [/tex]
[tex] \frac{v \times 7}{7} = 3 \times 7 \\ [/tex]
[tex]v = 21 \\ [/tex]
Answer:
- Option B is correct i.e. 21
Step-by-step explanation:
In the question we're provided with an equation that is :
- v/7 = 3
And we are asked to find the solution for the equation .
Solution : -
[tex] \longrightarrow \: \frac{v}{7} = 3[/tex]
Multiplying by 7 on both sides :
[tex] \longrightarrow \: \frac{v}{ \cancel{7} }\times \cancel{7} = 3 \times 7[/tex]
On further calculations , we get :
[tex] \longrightarrow \: \blue{\boxed{v = 21}}[/tex]
- Therefore , solution for equation is 21 .That means option B is the correct answer.
Verifying :
We are verifying our answer by substituting value of v in the equation given in question :
[tex] \longrightarrow \: \frac{v}{7} = 3[/tex]
Putting value of v :
[tex] \longrightarrow \: \cancel{\frac{21}{7}} = 3[/tex]
By dividing 21 with 7 , we get :
[tex] \longrightarrow \:3 = 3[/tex]
[tex] \longrightarrow \: L.H.S=R.H.S[/tex]
[tex] \longrightarrow \: Hence , \: Verified.[/tex]
- Therefore , our answer is valid .
