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:
3/4
Step-by-step explanation:
Change 2 1/4 into an improper fraction. 9/4 divided 9 by 3 and then put 4 underneath. You get 3/4.
Answer is 0.9
3.6÷4=0.9
0.9 is already a tenth
Unless you mean 4 divided by 3.6 then the answer is 1.1
4÷0.9=1.11111111 rounded to the nearest tenth it is 1.1
