Which calculation can be used to find the value of y in the equation y3 = 27

1 answer:

6 0

You just divide each side of the equation by three so you'll get $y = 9$

Edit: I believe you wrote the equation wrongly. If it was $y^3 = 27$ , then you cubic root both sides and get $y = 3$ .

Find the percent of change. Original: 80, new: 64

lara31 [8.8K]

Hi there!

To find the percent of change we can use the following formula:
$\frac{new - old}{old} \times 100\%$

Let's fill in our data
$\frac{64 - 80}{80} \times 100\% =$

Subtract
$\frac{ - 16}{80} \times 100\% =$

Divide
$- 0.2 \times 100\%$

And finally multiply
$- 20\%$

Hence, the percent of change is negative 20%.
