Bond [772]

The correct expression to simplify is:

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

Answer:

5.5n-1/2p-2

Explanation:

<u>1. Given expression</u>:

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

<u>2. Group like terms</u>:

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

<u>3. Simplify</u>:

  • 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

Devaughn is 8 years older than Sydney. The sum of their ages is 64. What is Sydney's age?
Zigmanuir [339]

Answer:

Sydney's age is 28

Step-by-step explanation:

Let Devaughn be D

And Sydney be S

D=S+8..... equation 1

D+S=64...... equation 2

Substitute equation 1 to equation 2

S+8+S=64

2S+8=64

2S=64-8

2S=56

S=56/2

S=28

Hope it helps

Good luck
