turn your inequality sign the other way ...
In a typical year, a willow tree grows 3.5 feet, while a Chitalpa tree grows 2 feet. Suppose a 6-foot willow tree and a 13-foot Chitalpa tree were planted at the same time.
- Write an inequality to describe when the willow tree is taller.
in writing the inequality I did this:
6 + 3.5y < 13 + 2y
Did I understand this right?
so the inequality correctly stated is:
6 + 3.5y > 13 + 2y
If I want to solve this:
1.5y > 7
1.5/1.5y > 1.5 /7
y > 4.67
I don't know why, but it doesn't look right to me. I am trying to understand this. Does that mean in 4.67 years the Willow tree will be at even height of the Chitalpa?
