Collin did the work to see if 10 is a solution to the equation r/4=2.5
Natasha2012 [34]

Answer:

Yes, because if you substitute 10 for r in the equation and simplify, you find that the equation is true.

Step-by-step explanation:

\frac{r}{4}  = 2.5 \\ lhs =  \frac{r}{4}  \\  =  \frac{10}{4}  \\  = 2.5 \\  = rhs \\  \therefore \:  \frac{r}{4}  = 2.5 \\

1. Mr.Customs is correcting the class’s math homework on customary units. Which of the following measurements is reasonable?
frosja888 [35]

Answer:

The reasonable measurement in question 1 is D - the distance from New York to California is 2,250 miles.  The best unit of measurement for the length of the distance of your textbook is A - inch.  

Step-by-step explanation:

The United States uses the Imperial System of measurement which uses things such as inches, feet, yards and miles.  In order to understand reasonable measurements, you need to first realize the order in which size would be determined.  For instance, 12 inches is equal to one foot, which can be found on your typical ruler.  Additionally, three feet is equal to one yard, which we can find on a yard stick.  Lastly, there are 1,760 yards in one mile, which is typically measured with some time of pedometer/odometer.  So, when you think about calculating measurement for common things such as a pencil or distance between cities, think about whether this distance could be measured using a ruler or perhaps the odometer on a car.
