Hey ! there
Answer:
- Value of expression is -47 . That means Option A is correct answer .
Step-by-step explanation:
In this question we are provided with an expression that 5 ( v - 10 ) - 7 and value of v as 2 . And we are asked to find the value of expression when value of v is 2 .
Solution : -
[tex] \quad \: \longmapsto \qquad \: 5(v - 10) - 7[/tex]
Step 1 : Substituting value of v as 2 :
[tex] \quad \: \longmapsto \qquad \:5(2 - 10) - 7[/tex]
Step 2 : Solving parenthesis :
[tex] \quad \: \longmapsto \qquad \:5( - 8) - 7[/tex]
Step 3 : Multiplying 5 with -8 :
[tex] \quad \: \longmapsto \qquad \: - 40 - 7[/tex]
Here we get ,
[tex] \quad \: \longmapsto \qquad \: \pink{\underline{\boxed{\frak{- 47}}}}[/tex]
- Henceforth , value of expression when v = 2 is -47 .
- Therefore , Option A is the valid answer.
