Answer:
As a reduced fraction:
minutes, which is 24 minutes
Step-by-step explanation:
Sam's speed is 1 lawn in 40 minutes. Vanessa's speed is 1 lawn in 60 minutes. If they both work together, the total speed is:

Which means that the total speed would be 5 lawns in 120 minutes. To find the time it would take to mow one lawn at that speed, we need to invert that speed so we get minutes per lawn:

Answer:
12 kilograms
Step-by-step explanation:
Let's construct an equation for her profits, we will call it P(x), where x is the number of kilograms produced/sold.
We know she has -$108 profit from buying supplies, and for each kilogram she produces, she earns -$16 (or loses $16, if earning negative money bothers you). However, we also know that she earns $25 per kilogram sold.
Constructing the equation with this information, we get: 
Setting this equation to zero and solving for x:



Step-by-step explanation:
- <em>perimeter</em><em>(</em><em>P)</em><em>=</em><em>3</em><em>+</em><em>4</em><em>+</em><em>4</em>
- <em>3</em><em>+</em><em>4</em><em>+</em><em>4</em>
- <em>1</em><em>1</em>
