Problema Solution
Dr. Root re rods measurements of a vine she is studying. Compared to the first measurement, the vine has quadrupled in length. It is now more than 48 centimeters long. Use an inequality to show how long the vine might have been when dr. Root first measured it.
Answer provided by our tutors
let x = the length of the vine when dr. Root first measured it
Compared to the first measurement, the vine has quadrupled in length: 4x
It is now more than 48 centimeters long:
4x > 48 divide both sides by 4
x > 12
the length of the vine was more then 12 cm when Dr. Root first measured it.
