They subtracted 1/3 from both sides instead of dividing 1/3 from both sides
pashok25 [27]3 years ago
4 0

Answer:

x= 15

Step-by-step explanation:

Francisca's mistake was that when she had an equation 5 = \frac{1}{3} x instead of dividing both sides by  \frac{1}{3}  she substracted  \frac{1}{3}  from both sides. So the correct way would be...

5 = \frac{1}{3} x\\\\(5)(3) = (\frac{1}{3} x )(3)

15 = x

Find the value of x. Round your answer to the nearest tenth. tan 12 degrees= ten over (x)
Lorico [155]
Tan(12)=-0.6358599287. That means -0.6358599287 = 10/x so you can swap the x to the other side to make x = 10/-0.6358599287 Which equals -15.7 rounded to the nearest tenth.
