Answer:
c=3d
Step-by-step explanation:
What equation models the data in the table if d = number of days and c = cost? Days Cost 2 6 3 9 5 15 6 18
Answer: An equation is a statement used to show the relationship between variables and shows the equality between two expressions. We want to find the relationship between the number of days and the cost.
Given that:
Days Cost
2 6
3 9
5 15
6 18
Lets take the ratio of days to cost using the first row:

The relationship c = 3d is true for all values of days and cost
Answer:
7x+5
Step-by-step explanation:
2x+5+2x+3x
=2x+2x+3x+5
=7x+5
7) -5-x=0
x=-5
8) 4x-36=0
4(x-9)=0
x-9=0
x=9
The first thing we must do to solve the problem is to define the variables.
We have then:
n: pounds of grapes
c: total price
We have to:
"The price of grapes at a farm is $ 1.85 per pound"
Therefore, the equation will be:
c = 1.85n
Answer:
c = 1.85n
