First, we'll set up two equations. One for the amount of each coin and another for the value of the coins.
N will represent nickels
D will represent dimes
N + D = 30
---The problem tells us that there are 30 total coins
0.05N + 0.10D = 2.95
---Nickels are worth 5 cents and dimes are worth 10 cents, and the total value of the coins is 2.95
Now that we have our equations, we need to solve for one of the variables in the first equation. I will solve for N.
N + D = 30
N = 30 - D
Then, we take that equation and substitute our new value for N into the second equation (value) and solve for D.
0.05(30 - D) + 0.10D = 2.95
1.5 - 0.05D + 0.10D = 2.95
1.5 + 0.05D = 2.95
0.05D = 1.45
D = 29
Now that we know how many dimes there are, we can plug that value into our equation for N and solve for N.
N = 30 - D
N = 30 - 29
N = 1
Therefore, there are 29 dimes and 1 nickel.
Hope this helps!
I believe that the answer would be D, there is a relationship between price and gift baskets sold, and the relationship is that as the price increases, the gift baskets sold decreases.
Despite the fact that there is an outlier, the point representing the 80 gift baskets sold at $52, there is still a pattern which shows that as the price of the baskets increases, the number of sales decreases based on the other points.
Answer:
The exponential grows at approximately four times the rate of the quadratic.
Answer:
105
Step-by-step explanation:
X - 32 = 73
Carry over the like terms (which is 32) to the 73 to remain with the x (the unknown)
x = 73 + 32
As we carry over the like terms, if the number is a positive on the left hand side or LHS, it will be a negative number on the right hand side or RHS as shown above.
x = 73 + 32
x = 105
Therefore x is 105
TO FIND OUT IF THE ANSWER WAS CORRECT, JUST CALCULATE IT AS THE EQUATION STATES :
X (105) - 32 = 73
