Answer:
$15
Step-by-step explanation:
Let's start by figuring out how much 1 cup of oil costs.
12 cups of oil is 36$
Let's set up a proportion.
12/36=1/x
Cross Multiply
12x=36
Divide both sides by 12.
x=3
1 cup of oil is $3.
Dinesh makes 5 batches of hummus, and each batch requires 1 cup of oil.
5*1=5
This means he needs 5 cups of oil.
5*3=15
He used $15 worth of oil in the 5 batches of his recipe.
However, since it is impossible to buy 5/12 bottles of oil, he would have needed to spend $36.
Given:
The given function is:

To find:
The value of x that is in the domain.
Solution:
Domain is the set of input values.
We have,

We know that the square root is defined for non negative values. So,



Thus, the domain of the given function is all real number that are greater than or equal to 7.
In the given options 0, -3, 6 are less than 7 but 8 in option A is the only value that is greater than 7. So,
is in the domain of the given function.
Therefore, the correct option is A.
Answer:
Molly paid for each song $1.5
Step-by-step explanation:
Let
x ------> amount that Molly paid for each song
we know that
The amount that Molly paid for each song multiplied by 8 is equal to the gift card value
so
The linear equation that represent this problem is

Solve for x
Divide by 8 both sides


Molly paid for each song $1.5
100 times as bigger because it is in the 109s
