Answer:
A ratio table is a structured list of equivalent (equal value) ratios that helps us understand the relationship between the ratios and the numbers. Rates, like your heartbeat, are a special kind of ratio, where the two compared numbers have different units
and the number of dimes that Victoria has. Define the variables that you use to write
the system.
Answer:
0.05n+0.10d=1.90
n=d+2
Step-by-step explanation:
One nickel is worth $0.05, so n nickels are worth 0.05n. One dime is worth $0.10, so dd dimes are worth 0.10d.The total 0.05n+0.10d equals $1.90:
0.05n+0.10d=1.90
Since there are 2 more nickels than dimes, there are more nickels, so if we add 2 to the number of dimes, we will get the number of nickels, meaning nn equals d+2.d+2.
n=d+2
From the problem, we create a system of equations that represent the value and quantity of nickels and dimes Victoria has. The system is: 0.05N + 0.10D = 1.90 and N = D + 2, where N represents nickels and D represents dimes.
The problem is about finding the number of nickels and dimes Victoria has. To do this, we will use a system of equations. We'll define N as the number of nickels and D as the number of dimes.
The first equation is based on the total value: since a nickel is worth $0.05 and a dime is worth $0.10, Victoria's coins add up to $1.90 - hence 0.05N + 0.10D = 1.90
The second equation is based on the quantity of coins: Victoria has 2 more nickels than dimes - hence N = D + 2.
Therefore, the system of equations is:
