Answer:
There are 23 quarters and 37 dimes in the collection
Step-by-step explanation:
Let's name the two unknowns we need to find :
Q = number of quarters in the collection
D = number of dimes in the collection
So our first equation on the number of coins we have in the collection can be written as:
Q + D = 60
Now let's write an equation that takes care of the total value of the collection ($ 9.45), having in mind that each quarter is worth $ 0.25, and each dime is $ 0.10:
So let's solve this system of linear equations in "Q" and "D" by substitution. We use the first equation to solve for "d" for example, and then use this to substitute for D in the second equation:
Then, there are 23 quarters in the collection. We can find the number of dimes via the substitution equation we used:

Answer:
There are 15 calories in 1 fluid ounce.
Step-by-step explanation:
To find the answer, you can use a rule of three to find the number of calories in 1 fluid ounce given that there are 120 calories in 8 ounces:
8 ounces → 120 calories
1 ounce → x
x=(1*120)/8
x=15
According to this, the answer is that there are 15 calories in 1 fluid ounce.
