Mr. Brown had a orchard of apple trees, a fire took out thirty trees. The remaining trees produced 130 apples each for a total of 11,700 apples. How many apple trees did Mr. Brown have before the fire. Mr. Brown started with x trees,

90

Step-by-step explanation: 11,700 divided by 130 is 90 Therefore Mr. Brown started with 90 apple trees. Hope this helps :) sorry if I'm wrong

x = 120 trees

Step-by-step explanation:

Since the trees he has left produces 130 apples each, and he ended up with 11 700 apples, it means he has left 11 700 / 130 = 90 trees.

Now, since he lost 30 trees in the fire, it means before he had 30 more trees => 90 + 30 = 120 trees

The equation for it:

( x - 30 ) * 130 = 11 700

x - 30 = 11 700 / 130

x = 90 + 30

x = 120

correct answer:

a + bi

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)
