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 second and thrid one :)
Step-by-step explanation:
Answer:
5 3/4+7 1/2
5.75 + 7.50 = 13.25 or 13 1/4
Step-by-step explanation:
5 3/4+7 1/2
5.75 + 7.50 = 13.25 or 13 1/4
No that’s equivalent to 7 + 7x
Answer:
Y=3/5x -4/5
Step-by-step explanation:
3/5 is the slope so you do 3/5x
-4/5 is negative because the line passes two negative coordinates
Hope this helps!
