The answer would be B simply because it sounds more reasonable.
Answer:
if the interest rate is anual, after 20 years the account would have $2400
Explanation:
(interest rate • $$$ invested • amount of time) + $$$ invested = $$$ after total amount of time
(0.07 • 1000 • 20) + 1000 = 2400
I got the answer as 10,560 per min
Answer:
17
Step-by-step explanation:
(x+28y)/x =50
Multiply each side by x
(x+28y)/x *x =50*x
x+28y = 50x
Subtract x
x-x+28y = 50x-x
28y = 49x
Divide by y
28y/y = 49x/y
28 = 49 x/y
Divide by 49
28/49 = x/y
We want to find
(y+28x)/y
Rewriting as
y/y +28 (x/y)
1 + 28(x/y)
Replacing x/y with (28/49)
1 + 28(28/49)
1 +28*28/49
1+784/49
1+16
17
Answer: 19nickels and 7dimes.
Ps i really don’t know where the 50.05 came from if it is suppose to be there then I really don’t know how to solve this.
Step-by-step explanation:
Ok so if you know that there are 19nickels, let n=number of nickels.
The number of total coins subtracted by number of nickels will give you number of dimes.
165-number of nickels=number of dimes
Value of dimes=10(number of dimes) or total value of dimes/individual value (10cent)
Then you can substitute total as $1.65 and get the value of nickels by multiplying by 5cent ( my teacher taught me using whole numbers to make it easier so I turned $1.65 to 165 cent). Since the value of the dimes is the value of nickels subtracted from the total, I can subtract 95 from 165 and divide the difference by 10, to get the number of dimes.
5(n)=5(19)=95
(165-95)/10=number of dimes
70/10=7dimes
You can check by multiplying 7x10 and 5x15 again and adding them together to see if they equal 165 cent.
