Question

Evaluate 6t - 20 - 32u when t= 6 and u = 1/4

Answer 1

6t - 20 - 32u=
6(6)- 20 - 32(.25)=
36-20-8=
8

Answer 2

Answer: The required value of the given expression is 8.

Step-by-step explanation: We are given to evaluate the following expression for t = 6 and
`u=(1)/(4):`

`E=6t-20-32u~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)`

To evaluate the given expression, we must substitute the values of t and u in (i).

From (i), we get

`E\\\\=6t-20-32u\\\\=6* 6-20-32*(1)/(4)\\\\=36-20-8\\\\=36-28\\\\=8.`

Thus, the required value of the given expression is 8.
