Answer: There are 27 trees that Abe can plant in each row. And there are 1 pine tree and 2 oak tree in each row.
Explanation:
Since we have given that
Number of oak trees = 54
Number of pine trees = 27
According to question, we have given that Abe wants to plant the trees in rows that all have the same number of trees and are made up of only one type of tree.
So, the greatest number of trees is given by
Hence, there are 27 trees that Abe can plant in each row.
Therefore, there are

Step-by-step explanation:
Given that z² is directly proportional to w then the equation relating them is
z² = kw ← k is the constant of proportion
To find k use the condition z = 4 when w = 8, thus
4² = 8k
16 = 8k ( divide both sides by 8 )
2 = k
(i)
z² = 2w ← equation of proportion
(ii)
When w = 18, then
z² = 2 × 18 = 36 ( take the square root of both sides )
z = 
= 6
(iii)
When z = 5 , then
5² = 2w
25 = 2w ( divide both sides by 2 )
w = 12.5

Answer:
<em>She need to subtract 7</em> from the left side to make a true equation again.
Step-by-step explanation:
The steps are given as:
suppose Malcolm adds 2 to the left side of an equation and subtracts 5 from the right side.
Now we are asked: What number should he now subtract from the left side to make a true equation again?
We know that if we apply any operation to one side of an equation than it must be applied to the other side as well in order to keep the statement true.
So now she need to subtract 7 from the left side to make a true statement.
( Because as she has subtracted 5 from the right.
and before that she has already added 2 to the left so now if she will subtract 7 from the left than the total change in the left will be: 2-7= -5 i.e. -5 is subtracted in the left which is equal to the operation applied to the right ).
