Answer:
<u>420 names were read</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Rate of names read per minute at the graduation ceremony = 5
2. If the names had been read at the rate of seven names per minute, the ceremony would have taken 24 minutes less. How many names were read?
x = Number of minutes it takes to read the names at the rate of seven names per minute
x + 24 = Number of minutes it takes to read the names at the rate of five names per minute
Solving for x:
5 * (x + 24) = 7x
5x + 120 = 7x
5x - 7x = -120 (Subtracting 120 and 7x at both sides)
-2x = -120
x = -120/-2
x = 60 ⇒ 7x = 420
<u>420 names were read</u>
Answer:
−(d+1)>3
Step 1: Simplify both sides of the inequality.
−d−1>3
Step 2: Add 1 to both sides.
−d−1+1>3+1
−d>4
Step 3: Divide both sides by -1.
