D 4.25 + 2.5x less than or equal to 25

Answer 1

D. 4.25 + 2.5x less than or equal to 25.

Explanation:

• 2.5x + 4.25 = 25
• - 4.25 on both sides

• 2.5x = 20.75
• divide by 2.5x on both sides
  x = 8.3
• round it down to 8
• plug in 8 for x.
• 2.5(8) + 4.25 = 24.25
  
• 24.25 < 25.
  which concludes, 4.25 + 2.5x is less than or equal to 25.
