Answer: 9 elm trees were removed.
Step-by-step explanation:
Let x represent the number of elm trees removed.
The total number of elm trees in the park is 22. Elm leaf beetles have been attacking the trees. After removing several of the diseased trees, there are 13 healthy elm trees left. The equation to find the number of elm trees that were removed would be
x + 13 = 22
Subtracting 13 from the left hand side and the right hand side of the equation, it becomes
x + 13 - 13 = 22 - 13
x = 9
Answer:
y = 4
Step-by-step explanation:
5x + y = -1
y = -1 - 5x
y = 6x + 10
6x + 10 = -1 - 5x
11x = -11
x = -1
y = 6x + 10 = 6(-1) + 10 = -6 + 10 = 4

Answer: Step-by-step explanation:
In order to answer this question you will need to find 2 distances and then add them to each other.
Begin at -29. How far will you have to move to the right 29 in order to get to 0?
Now how far will you have to more to get from 0 to 100?
Draw an open number line to help you.

-29 0 100
Your first distance is 29. Your second distance is 100. The total distance is 129.
