2 answers:
Answer:
c) 12x + 36 = 10x + 48
Step-by-step explanation:
We are given the following information:
Height of tree A = 36 inches
Growth rate of tree A = 12 inches per year.
Height of tree B = 48 inches
Growth rate of tree B = 10 inches per year.
If x is the number of years after which the tree will have same height.
Height of tree A in x years =
Height of tree B in x years =
Equating these equation,
Hence, option c) represents the correct equation such that the tress will have same height in x years.

Step-by-step explanation:
Given:
Profit made in previous financial year = $10 million
We need to write an equation to find the profit made by the business.
Solution:
Let the profit (in millions) made by business A be 'x'.
Let the profit (in millions) made by business B be 'y'.
Now given:
business B making 4 times as much profit as business A.
so we can say that;
Now we know that;
Profit made in previous financial year is equal to sum of profit (in millions) made by business A and profit (in millions) made by business B.
framing in equation form we get;
Substituting the value of y in above equation we get;
Hence The equation to find the profit made by business combined is .
On Solving above equation we get;
profit (in millions) made by business A =
profit (in millions) made by business B =
Hence Business A made $2 million profit and Business B made $8 million profit.
