Hello!
Let's write some important information contained in the exercise:
• hotdogs: $2.59 (,x,)
,
• hamburgers: $5.29 (,y,)
He needs 11 packages. Let's write it:
• x + y = 11
He spent a total of $39.29. We can write it as:
• 2.59x + 5.29y = 39.29
Now, let's solve these two equations as a linear system:
First, let's isolate x in equation A:
Now, we will replace where's x by 11-y in equation B:
As I called the hamburgers as 'y', we know that he bought 4 packages of hamburgers.
Answer:
the answer is
Step-by-step explanation:
The proportion of coconut milk in the cocktail is ml for every 15 ml of orange juice.
Proportion shows the fractional composition of a given quantity or substance.
So that:
orange juice = 15 ml
contents of the orange juice;
apple juice = 25 ml
coconut milk = 10 ml
total = 35 ml
So that;
the fraction of apple juice in the orange juice = x 15
=
the fraction of apple juice in the orange juice = ml
Also,
the fraction of coconut juice in the orange juice = x 15
=
the fraction of coconut juice in the orange juice = ml
Therefore, the proportion of the cocktail that is coconut milk is: for every 15 ml of orange juice, then ml of coconut juice is required.

Answer: 104.5 seconds
Step-by-step explanation:
Hi, to answer this question we have to apply proportions:
Six students eat 6 apples in 33 seconds.
The proportion is: number of apples eaten /time
6 apples /33 seconds = 6/33
For 19 apples:
19 apples / x seconds =19/x
6/33 = 19/x
Solving for x:
x = 19 / ( 6/33)
x = 104.5 seconds
