Two consecutive integers would be 13 and 14
because 13 x 13 = 169 and 14 x 14 = 196 and the inequality fits inbetween perfectly.
Slope like you wrote is rise over run. That means from the point given: (1,1) you will rise up by the first number and run to the left (negative)/right (positive) depending on the sign of the number.
EX: 5/2, rise up 5 and run to the right by 2. Your line’s direction should be pointed upwards.
EX: 2, your two numbers is 2 and the invisible 1 (apply the same method as the first example).
A group of 5 girls went to the library to study for an upcoming biology test. Each girl studied for the amount of time. If the total amount of time they spent studying was 8 hours, how long did each girl study for?
x represents how long each girl studied for
5x = 8 divide 5 on both sides and you get 1.6, so the amount each girl spent studying is 1 hour and 36 minutes
1. Find the unit rate
15 books divided by 5 days = 3 books sold per day.
Since we are looking for how many days it would take the store to sell 21 bucks, we could do 21 (amount of books) divided by 3 (how much books is sold in a day).
Therefore, it will take a week / 7 days to sell 21 books.
