For the first question the answer is C(n)=0.75n-0.25
for the second question the answer is y=2x
Answer:
108 cubic units
Step-by-step explanation:
V = 4 cubic units
v = (1/3)³ = 1/27 cubic units
V/v = 4/(1/27) = 4/1 x 27/1 = 108 cubic units
Answer:
you'd get the expression 6.37+7.8k
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.
