X is amount of books.
x ≤ 9 if the books are 2 inches thick.
x ≤ 18 if the books are 1 inches thick.
Equation for 1 inches.
x ≤ 18
Equation for 2 inches.
2x ≤ 18
Equation for both.
x + 2y = 18
y is amount of 2 inch books
This one equation above is standard form.
The distance between the two points would be 6.
Answer: The answer is 1/3 because you simplify your answer, and the answer is 1/3
Step-by-step explanation:
Answer:
240
Step-by-step explanation:
Since David has 60 fewer storybooks than Huiling, take the total number of storybooks, which is 460 and minus it by 60.
460-60=400
Now, there are 5 units, 5units=400
1unit=80
Since Jenny has 3 times as many storybooks as David, Jenny has 3 units, 3unit=80x3=240
