Chapter 2: Q12. (page 145)

Evaluate the expression $| 3 t - 2 u | + 5 v$ if $t = 2, u = - 5$ and $v = - 3$ .

Short Answer

Expert verified

The value of the given expression is $1.$

Step by step solution

Step 1. Given Information.

We have the expression $| 3 t - 2 u | + 5 v$ .

To find the value of the given expression when role="math" localid="1643090177102" $t = 2, u = - 5 and v = - 3$ .

Step 2. Apply the concept.

We substitute the given value of $t, u, v$ in the given expression and find the value of the expression $| 3 t - 2 u | + 5 v$ .

Step 3. Calculation.

Solving the given expression:

$\begin{array}{l} | 3 t - 2 u | + 5 v = | 3 (2) - 2 (- 5) | + 5 (- 3) \\ = | 6 + 10 | - 15 \\ = | 16 | - 15 \\ = 1 \\ \Rightarrow | 3 t - 2 u | + 5 v = 1 \end{array}$

Hence, the value of the given expression is $1.$
