Answer:
n = 2p
Step-by-step explanation:
14n + 6p – 8n = 18p
Combine like terms
14n-8n +6p = 18p
6n +6p = 18p
Subtract 6p from each side
6n+6p -6p = 18p-6p
6n = 12p
Divide by 6
6n/6 = 12p/6
n = 2p
The rate that is not equivalent to the others is "1 for $0.75".

How to find the rates?</h3>
To find the rates, you need to take the quotient between the price and the number of units, these rates, give the value of a single item in dollars.
Here, the four rates are:
- 1) $36/27 = $1.33...
- 2) $4/3 = $1.33...
- 3) $20/15 = $1.33...
- 4) $0.75/1 = $0.75
So we can see that the rate which is not equivalent to the others is the last one (the bottom right one).

answer: y = 1.5x - 5.5
explanation:
use y = mx +b to model your equation
(m = slope, b = y-intercept)
let's start by finding slope
to find slope, subtract the y values over the x values.
- 4 - (-1) / - 5 - (-3)
solve and simplify.
-3 / -2
two negatives equals a positive, so convert into a decimal and remove the negative
you get 1.5.
now, plug the slope a y and x value into the equation to find b, the missing value.
-1 = 1.5(3) + b
-1 = 4.5 + b
-5.5= b
so, your equation is y = 1.5x - 5.5.
