Question

Evaluate 8p +3q-188p+3q−188, p, plus, 3, q, minus, 18 when p=\dfrac12p= 2 1 ​ p, equals, start fraction, 1, divided by, 2, end fraction and q=7q=7q, equals, 7.

Answer 1

Answer: 7

Explanation:

Answer 2

Given:

The expression is

`8p+3q-18`

To find:

The value of the expression when
`p=(1)/(2)` and
`q=7`.

Solution:

We have,

`8p+3q-18`

Putting
`p=(1)/(2)` and
`q=7`, we get

`8((1)/(2))+3(7)-18`

`=4+21-18`

`=7`

Therefore, the value of the expression is 7 when
`p=(1)/(2)` and
`q=7`.
