Answer- 30
Step-by-step explanation:
About 10 songs because if you add up all ten numbers of all the songs then you divide, then you divide again you will get 10 songs
To solve this, it is easiest to set up a proportion, letting x represent the number that we don't know.
2/10 = x/5
Now, we can use cross products to simplify this proportion. Cross products sets the products of the numerator and denominator of separate fractions equal to one another. It results in the equation:
(5)(2) = (10)(x)
Let's multiply out these numbers to further simplify the equation.
10 = 10x
Finally, we have to divide both sides by 10, to get our variable x alone
x = 1
Therefore, 2 tenths is equal to 1 fifth.
Luis spent $9.50, in which:
Candy (y) = $1.25
Chips (x) = $0.50
$9.50 = 1.25y + 0.50x
Luis bought 10 snacks in all
10 = x + y
-----------------------------------------------------------------------------------------------------------------
You're answer:
x + y = 10
1.25y + 0.50x = 9.50
