17 3/4 - 2/5x = 4 1/2
-2/5x = 4 1/2 - 17 3/4
-2/5x = 9/2 - 71/4
-2/5x = 18/4 - 71/4
-2/5x = - 53/4
x = (-53/4) / (-2/5)
x = -53/4 * - 5/2
x = 265/8
x = 33 1/8 bottles
6.8 ounces would be used?
105 m = 2.5 h
x miles = 1 hour
You cross multiply since it's a proportion:
2.5 * x
105 * 1
=
2.5x = 105
Then you divide everything by 2.5
The answer is 42
Answer:
6%.
Step-by-step explanation:
We have been given that Tammy deposited $520 in the bank account that earns simple interest every year after 5 years she had earned $156.
To find the interest rate we will use simple interest formula.

I= Interest.
P= Principal amount.
r=Annual interest rate (in decimal form).
T= Time in years.
We have been given that I=156, T=5, P=520
Upon substituting our values in above formula we will get,




Let us multiply 0.06 by 100 to convert annual interest rate in percentage.

Therefore, the annual interest rate was 6%.
