Answer:
How does y vary with x?
This is called direct variation and to find proportionality, we use the formula y/x = K
Step-by-step explanation:
The first table's results would look like:
6:15
12:30
18:45
24:60
30:75
To do these, you divide the y values by the constant to receive x.

Answer:
5/4, 1.3, 1 8/25
Step-by-step explanation:
5/4 is equal to 1 1/4, which is 1.25
1.3 is still 1.3
1 8/25 is equal to 1.32, which is sliglightly greater than 1.3
<span>3y-6x=9
</span><span>3y = 6x + 9
y = 2x + 3
answer
</span> y = 2x + 3
Given expression:
for x = 3 and y = –2
(6) Mistake did by Grayson:
In second step, first to do 3² and then multiply with 4.
But Grayson first multiply 4 with 3 and then squared the expression.
This is wrong.
(7) Mistake did by Emily:
In third step, first to multiply 2 with (–2) using BODMAS rule and then add with 36.
But Emily first added 36 with 2 which gives 38.
This is wrong.
(8) Mistake did by Pat:
In first step, the y value given is –2.
But Pat substituted y value is 2.
This is wrong.
(9) Correct evaluation:



This is the correct way to evaluate the given expression.
1 meter is 100 centimeters
and 100 /5 = 20
It will take 20 books to get to 1 meter
