Set up and solve a system of equations to solve the problem.
1. Ajar contains n nickels and d dimes. There are 20 coins in the jar, and the total value of the
coins is $1.40.
How many nickels and how many dimes are in the jar?

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

replication and blocking

step-by-step explanation:

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
