Answer: 17 nickels, 8 dimes
Step-by-step explanation:
Since we are given system of equations, we can use elimination method to find n or d. First, let's eliminate n. To do so, we need to make sure they are equal to each other. Then, we would have to multilpy the second equaiton by 0.05.
0.05N+0.1D=1.65
0.05N+0.05D=1.25
Now, we can subtract the 2 equations.
0.05D=0.4
D=8
Now that we know the number of dimes, we can plug it into any of the equations to find nickels.
N+8=25
N=17
There are 17 nickels and 8 dimes.
Step 1: 25% = 1/4 Turn the percent into a fraction
Step 2: 10.99 x 1/4 Multiply the discount
Step 3: 2.75 Get the amount that will be discounted
Step 4: 10.99 - 2.75 Subtract the total cost by the discount.
Answer: $8.24
Answer:
The answer is B
Step-by-step explanation:
You add up all the numbers which should be 600 and divide by the total amount numbers used.
600/15=40.
Answer:
Area = 406
Step-by-step explanation:
First things first: Divide the shape
Here is how I did it:
21 x 16
14 x 5
Now solve:
21 x 16 = 336
14 x 5 = 70
Now add:
336 + 70 = 406
So the area is 406
