Answer:
<h2>7 ft</h2>
Step-by-step explanation:
let the height height of the tree be "h"
Hence the tree's height h=9 ft
one year later,let the height of the tree increased by x ft
hence
--------This is the equation for the growth of the tree
In order to solve for the added height(growth) of the tree we need to solve for x
Answer: can’t really see it
Step-by-step explanation:
The cost of an apple pie is $13 and a blackberry pie is $18.
<h3>How to find the cost?</h3>
Let A be apple pies and B be blackberry pies.
3A + 11B = $237
3A + 12B = $255.
On solving the quadratic equation, we get
-B = -18
Therefore,
B = 18
Substitute B in any one of the equations,
3A + 11*18 = 237
3A = 237 - 198
A = 39/3
A = 13
The cost of an apple pie is $13 and a blackberry pie is $18.
