Answer:
Step-by-step explanation:
Let t represent the number of years.
We have been given that When Joseph first starts working at a grocery store, his hourly rate is $10.
For each year he works at the grocery store, his hourly rate increases by $0.50. Increase in hourly rates after t years would be 
The hourly rates after t years will be 10 plus .
We can represent this information in an equation as:
Therefore, the function represents Joseph's hourly rates after t years.
3 times the product of 5 and b is reduced by 2
3*(5*b)-2
15b-2
The answer is: 
The explanation is shown below:
1. Cynthia rounds the number, which is identified as 
, to one decimal place and the result is 6.3.
2. Based on this, we know that could have been between 6.25 and 6.35. Therefore, the error interval for is given by:
Where 
indicates that the value 6.25 is included and 
indicates that the value 6.35 is not included (Because if had been exactly 6.35, Cynthia would round up to 6.4).
Answer:
Step-by-step explanation:
L=2W-4
40=2L+2W
The first equation uses the information that the length of a rectangular rug is 4 feet less than twice its width.
The second equation is using your standard perimeter equation of 2L+2W=perimeter of a rectangle.
Hope this is helpful :)
