Question

Simplify this expression.

1 + 4.25n + 32p – 3 + (–2p) + 54n
A. 5.5n – 12p – 2
B. 9.5n + 1.5p – 2
C. 94n − 1.5p − 4

Answer 1

The correct expression to simplify is:

`1+4.25n + 3/2p -3+(-2p)+5/4n`

Answer:

`5.5n-1/2p-2`

Step-by-step explanation:

1. Given expression:

`1+4.25n + 3/2p -3+(-2p)+5/4n`

2. Group like terms:

`(1-3)+(4.25n+5/4n)+(3/2p-2p)`

3. Simplify:

• 1 - 3 = - 2

• 4.25n + 5/4n = 4.25n + 1.25n = 5.5n

• 3/2p - 2p = 1.5p - 2p = - 0.5p = - 1/2p

`-2+5.5n-1/2p=5.5n-1/2p-2`
