PLEASE HELP!!!!!!!! :/

Answer 1

Hey ! there

Answer:

• Value of expression is -47 . That means Option A is correct answer .

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 : -

`\quad \: \longmapsto \qquad \: 5(v - 10) - 7`

Step 1 : Substituting value of v as 2 :

`\quad \: \longmapsto \qquad \:5(2 - 10) - 7`

Step 2 : Solving parenthesis :

`\quad \: \longmapsto \qquad \:5( - 8) - 7`

Step 3 : Multiplying 5 with -8 :

`\quad \: \longmapsto \qquad \: - 40 - 7`

Here we get ,

`\quad \: \longmapsto \qquad \: \pink{\underline{\boxed{\frak{- 47}}}}`

• Henceforth , value of expression when v = 2 is -47 .
• Therefore , Option A is the valid answer.
