1. The equation that represents Layla's fees according to the information provided is: y= 2x+3, where:

y is the amount earned

x is the number of days

2. The equation that represents Sam's fees according to the information provided is: y= 3x, where:

y is the amount earned

x is the number of days

3. In the graph, you can see that there is a point in which the two lines intercept. In that point, both earn the same amount that is 9 and the number of days is 3. Also, you can find the answer doing the following:

2x+3= 3x

3= 3x-2x

x= 3

Layla and Sam will earn the same amount for dog sitting after 3 days.

-That amount is: $9.

2x+3= 2(3)+3=  9

3x= 3(3)= 9

For a summer block party, Elsa is bringing cups and a large ice cream
Klio2033 [76]

Answer:

Look bucko this story will help u, make sure to read it all!

Step-by-step explanation:

She tried to explain that love wasn't like pie. There wasn't a set number of slices to be given out. There wasn't less to be given to one person if you wanted to give more to another. That after a set amount was given out it would all disappear. She tried to explain this, but it fell on deaf ears.

Cake or pie? I can tell a lot about you by which one you pick. It may seem silly, but cake people and pie people are really different. I know which one I hope you are, but that's not for me to decide. So, what is it? Cake or pie?

It was a concerning development that he couldn't get out of his mind. He'd had many friends throughout his early years and had fond memories of playing with them, but he couldn't understand how it had all stopped. There was some point as he grew up that he played with each of his friends for the very last time, and he had no idea that it would be the last.

She nervously peered over the edge. She understood in her mind that the view was supposed to be beautiful, but all she felt was fear. There had always been something about heights that disturbed her, and now she could feel the full force of this unease. She reluctantly crept a little closer with the encouragement of her friends as the fear continued to build. She couldn't help but feel that something horrible was about to happen.

I'm heading back to Colorado tomorrow after being down in Santa Barbara over the weekend for the festival there. I will be making October plans once there and will try to arrange so I'm back here for the birthday if possible. I'll let you know as soon as I know the doctor's appointment schedule and my flight plans.

She reached her goal, exhausted. Even more chilling to her was that the euphoria that she thought she'd feel upon reaching it wasn't there. Something wasn't right. Was this the only feeling she'd have for over five years of hard work?

At that moment he had a thought that he'd never imagine he'd consider. "I could just cheat," he thought, "and that would solve the problem." He tried to move on from the thought but it was persistent. It didn't want to go away and, if he was honest with himself, he didn't want it to.

You can decide what you want to do in life, but I suggest doing something that creates. Something that leaves a tangible thing once you're done. That way even after you're gone, you will still live on in the things you created.

He looked at the sand. Picking up a handful, he wondered how many grains were in his hand. Hundreds of thousands? "Not enough," the said under his breath. I need more.

There once lived an old man and an old woman who were peasants and had to work hard to earn their daily bread. The old man used to go to fix fences and do other odd jobs for the farmers around, and while he was gone the old woman, his wife, did the work of the house and worked in their own little plot of land.
