Answer:
final cost of 3 pounds: <u> 8 dollars </u>
final cost of p pounds: <u> 3.75p - 3.25 dollars </u>
Step-by-step explanation:
Each pound costs $3.75, so 3 pounds cost 3*3.75 = 11.25 dollars. Subtract off the $3.25 to get the final cost to be 11.25-3.25 = 8 dollars. This takes care of the first part.
For the second part, the expression for the final cost is 3.75p - 3.25; where the 3.75p is the cost before the coupon is applied. If you plugged p = 3 into that expression, you should get 8 as a result. The variable p is some positive whole number. It's a place holder for the number of pounds of apples.
As you can see in the picture below, it's not possible to create a triangle that has side lengths of 4, 8, and 3
triangle inequality theorem, impossible triangle
It turns out that there are some rules about the side lengths of triangles. You can't just make up 3 random numbers and have a triangle! You could end up with 3 lines like those pictured above that cannot be connected to form a triangle.
The mistake he made was that he did not consider units of measurement while comparing the lengths
He has to convert the both quantities into the same unit to compare the lengths either centimeters to meters or meters to centimeters
Step-by-step explanation:
Length of desk = 1 meter
Henry's name tag = 8 cm
Henry says that his name tag is 7 cm longer than the desk. The mistake he made was that he did not compare the units of both quantities. He just subtracted 1 from 8 and got 7. Meter is a larger unit and centimeter is a smaller unit. In order to compare the lengths of the desk and his name tag the units have to be same.
Hence
The mistake he made was that he did not consider units of measurement while comparing the lengths
He has to convert the both quantities into the same unit to compare the lengths either centimeters to meters or meters to centimeters
