x
Answered by GPT 3.5
To find the cost of 8 plants, we can set up a proportion:

5 plants / $16.20 = 8 plants / x

To find x, we can cross multiply and solve for it:

5 * x = 8 * $16.20
5x = $129.60
x = $129.60 / 5
x = $25.92

Therefore, the cost of 8 plants would be $25.92.

Paige should use the answer choice "500feet²" to express her final solution since it is the most appropriate unit for measuring the area of a pound.

Subtraction Property of Equality justifies this operation.

In the original equation, Zayn added 9 and 12 to both sides to isolate the variable. By subtracting 21 from both sides in the next step, he further simplified the equation to solve for x.

None of the above.

The correct solution for the equation ax+b=c, solved for a, is:
a = (c-b)/x
