The conversion factor between kilo and base unit which is grams in this question is 1000 so there is 1000 grams in 1 kilogram so first we need to convert kilograms to grams so we multiply by 1000 so 30kgx1000= 30000 grams so to find the number of crayons then we divide by 30 which is the mass of one crayon to find out how many we need so 30000/30= 1000 so you would need 1000 crayons
We have,
x+y:x-y=3:2
To prove that, x+ y : x - y = 3:2.
x+y=3
And,
x+y = 2
Adding (1) and (2), we get
x+y+x-y=3+2
⇒2x=5
⇒ x =
Put x = in (1), we get
+y=3
⇒ y=3-=
x+y:x-y=
=3:2
So, x+y:x-y=3:2.

Answer: A. c = 3d
I'm gonna go with c = 3d
Step-by-step explanation: c = 3d
After looking at the table I believe the equation would be c=3d. I came to this conclusion because (6)=3(2); (9)=3(3); (15)=3(5); 18=3(6). I really hope this helps!:)

Answer:
Step-by-step explanation:
Days Cost
2 6
3 9
5 15
6 18
Now to find equation that models the given data we will use two point slope form.
Formula:
Substitute the values in the formula
where y denotes the number of days and x denotes the cost
Let us suppose d denotes the number of days and c denotes the cost
So, equation becomes:
Hence an equation models the data in the table is
So, option A is true.
