Answer:
64 textbooks
Step-by-step explanation:
the first two teachers had 21 students each that's 21+21=42
the other teacher had 22 students so apparently all the textbooks handed to the students are,21+21+22=64
Each book is 2.4cm thick; that means if you're stacking books on top of each other, that is, on their sides, each book will be 2.4 cm tall. multiply the length of each book (2.4cm) by 21 to figure out how tall 21 books together will be. 2.4 x 21 = 50.4. the shelf needs to be at least 50.4cm tall.
The answer is 600. 572 rounded to the nearest hundred is 600
Answer:
Substitute point (4, 8)
y = y1 + m(x - x1)
y = 8 + m(x - 4)
y = 8 + mx - 4m
let m = 3 (It can be anything) Substitute m into equation:
y = 8 + (3)x - 4(3)
y = 2x - 4
