Question 565302
You plant a 14 inch hemlock tree that grows at a rate of 4 inches per year.
You also plant a 8 inch spruce that grows at a rate of 6 inches per year.
In how many years will both trees be the same height, and how tall will they be.
:
Let x = no. of yrs for them to be equal
:
Write an expression for each tree (which is what you did)
Hemlock: 4x + 14
Spruce: 6x + 8
:
When they are equal
6x + 8 = 4x + 14
Find x
:
Then replace x with it's value to find the height of each tree, of course they should be equal.
