Let x be the <span>heights of a maple tree and y be the height of the cherry tree.
We know:
</span>

<span>The new ratio is obtained like this:
</span>

.
From the above equation we get

.
then

Solving the above equation for y we get:

So
So the first tree is (400-160=240) more taller than cherry tree.
If there are multiple operations at the same level on the order of operations off from left to right and you work like this first noticed that there are no parentheses or exponents so we moved to multiplication and division with any sense of parentheses
Vas happenin!!
The last option is correct… She flipped the Y values and the X values it would be 4-12÷9-7
Hope this helps

It would be C because a coefficient is always with a variable and 6 is with a variable which makes it a coefficient
Hope this helps
