The equation y=2.54x gives the length y in centimeters corresponding to a length x in inches. What is the length in centimeters of a 1-foot ruler? Help please!!!!!!

Question

anonymous · Answer

X is the length in inches. Convert 1ft to inches. Plug in for x and solve. You will get a result in inches. Then convert the result to cm.

anonymous · Answer

i think there are 12 inches in one ft, so you'd just have to plug in 12 for x and solve for y to get an answer for 1ft in cm

anonymous · Answer

Sorry, as per the question, the result is in cm, so no final conversion necessary/

i did this: 2.54(12) and got 30.48 no what?

That is correct, 1 foot = 30.48 cm

@jim_thompson5910, ok so thats the right answer?

jim_thompson5910 · Answer

The formal way to do this is

y=2.54x

y=2.54(12) .. Plug in x = 12 (since 12 inches = 1 foot)

y = 30.48
