Step-by-step explanation:
x = price per video game
y = price per CD
164 = 5x + 3y
and then we know
x = y + 12
now we can use this as substitute in the first equation :
164 = 5(y + 12) + 3y = 5y + 60 + 3y = 8y + 60
104 = 8y
y = $13
x = y + 12 = 13 + 12 = $25
so, each CD costs $13.
Answer:
n-5=6
Step-by-step explanation:
five less than a number is represented by n-5 and then it is equal to 6
<span>5(x - 2) + 2x
= 5x - 10 + 2x
= 7x -10
answer
</span>7x -10
We can easily convert grams to pounds and find that 1 g of coffee beans is 0.00220462 pounds. Now we can multiply that value with 60 cups to find how many cups it makes.
We find that it makes 0.1322772 cups.
Then we know that 236.588 milliliters are in a cup. We multiply the value of the coffee available with 1 g of coffee beans (in cups - of course) and get the value the question asked :
0.1322772 * 236.588 milliliters
The answer is 31.2951981936 milliliters!
Hope this helps!
