Answer:
im doing the same work but i am working on it ill help you afterwards when i am done .
Step-by-step explanation:
Pilar started with 80 and adds 10 each week.
y= 10x + 80 (ten seashells • weeks + 80 she started with)
Marisol started with 0 and adds 20 each week.
y = 20x (no need to add + 0 because she started with nothing)
Inequality:
y = 10x + 80 < y = 20x
Weeks:
I would reccomend just plugging in numbers (for example if I put in 5 I would determine if it was too high or low then go to the next number.)
I plugged it into an online graph so I can’t show my work but the answer is 8 weeks.

A×4. C×2
A×3. C×4
A×2. C×6
A×1. C×8
To start, let's define our variable, which is x. x will represent the width of the rectangle. Next, since you know that the length is 4 times as long as the width, it will be represented by 4x. Now, since you know that the perimeter of a figure is the sum of the length of all the sides of the rectangle, you can express the perimeter with this expression: 4x+4x+x+x
Then, you set the expression to the perimeter, which is 110.
4x+4x+x+x=110
Combine like terms: 10x=110
And solve for x: x=11
Now that you have solved for x, which represents the width of the rectangle, you now know that your answer is 11.
