<h2>
There are 120 pine trees and 180 maple trees.</h2>
Step-by-step explanation:
Total number of trees = 300
Given that for every two pine trees there will be 3 maple trees.
Let 2t be the total number of pine trees.
Then total number of maple trees is 3t.
Total number of trees = 2 t + 3 t = 5 t
That is
5t = 300
t = 60
Total number of pine trees = 2t = 2 x 60 = 120
Total number of maple trees = 3t = 3 x 60 = 180
There are 120 pine trees and 180 maple trees.
Answer:
−1 ≤ n + 7 < 9
To solve a compound inequality separate it into two inequalities
That is
n + 7 ≥ - 1 and
n + 7 < 9
Solve the inequality
n + 7 ≥ -1
n ≥ - 8
and
n + 7 < 9
n < 7 - 9
n < 2
Find the intersection
The final answer is
-8 ≤ n < 2
