Answer:
C is the correct answer
Step-by-step explanation:
Step-by-step explanation:
Let's represent the two integers with the variables
and
.
From the problem statement, we can create the following two equations:


With the first equation, we can subtract
from both sides to isolate the
variable to the left-hand side:

Now that we have a value for
, we can plug it into the second equation and solve for
:


Now, let's move everything to one side of the equation:

Factoring this quadratic will give us two values for
:


Since we now know
, we can plug this back into either of the original equations to get a value for
, which will be
.
So the two numbers that sum to
and have a product of
are
.
<span>One nickel is 0.077 inches thick. Thus, a stack of nickels that is 100 inches tall would be composed of 100 divided by 0.077 nickels. So, a stack of nickels 100 inches tall would need 1299 nickels.</span>
Hi! It will be a pleasure to help you finding the solution to this problem, so let's solve each part:
<h2>PART 1.</h2><h3>Finding the correct expression.</h3><h3>Correct answer:</h3>

From the problem, we know the following data of the problem:
- Laval parked at the beach.
- Laval paid a fixed price of $4 for a pass.
- Laval paid $1.50 for each hour.
Our goal is to find the the expression for the total cost for parking at the beach for h hours. So:
Step 1: Since we have a fixed price, this value will appear in our expression:

Step 2: Since Laval paid $1.50 for each hour, this can be represented as the following expression:

Finally, we can write total cost (C) as the sum of these two expressions:

Finally, our correct option is A:

<h2>PART 2.</h2><h3>Finding h.</h3><h3>Correct answer:</h3>
5 hours
Here we have to find how many hours Laval spent at the beach knowing that he paid a total amount of $11.50. From the previous part, we know that our expression is:

Finally, he spent 5 hours at the beach
