Answer:
3x+4=40
Step-by-step explanation:
Lets take "x" as the number of students who went on the trip last year
It says "3 times" the number of seventh grade students that went on the trip last year so we know that x will be multiplied by 3
It also says 4 more than so we know that 3x+4 is gonna be part of the equation
If 40 students went on this years trip then 3x+4=40
62 days = 1364 pages
1 day = x
62x = 1364
x = 1364/62
x = 22 pages each day
The answers are:
8.5
5.7
21.9
Remember, percent is always out of 100. If you have 22%, you have 22 people per every 100 people, or, 22/100.
22/100 is the incomplete answer because it needs to be simplified. If you divide both numbers by two you get 11/50 which is the lowest fraction you can have because 11 is a prime number.
