Answer: x=9

Explanation: begin by substituting or replacing “y” with 4x since y=4x. This should give you the new equation of 4x=8x-36. Then subtract 8x from both sides so that it will cancel out 8x and leave you with 4x-8x=-36. Then combined like terms to then give you -4x=-36. Lastly, divide each side by -4 which will give you the answer of x=9 because when you divide -4 by -36, two negatives cancel each other out and leave you with a positive outcome.

A weed called the raindrop vine is known for growing at a very fast rate.
Vinvika [58]

First, we need to convert 0.75 feet to inches.

0.75 feet = 9 inches

Now, we need to divide 9 by how many hours are in a day, which is 24.

9/24 = 0.375

The raindrop vine can grow up to 0.375 inches per hour.
