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

4.5w = 5.1w - 30<br><br> Please help!!!
Lelu [443]
4.5w = 5.1w - 30

4.5w - 5.1w = -30

-0.6w =-30

Divide both sides by -0.6

-0.6w/-0.6 = -30/-0.6

<span>w = 50

In triangle abc, the angle c is six times as large as angle
mote1985 [20]
The interior angles of a triangle add up to 180 degrees

a = 1st angle, b = 2nd angle, c = 3rd angle

c = 6a
b = a + 60
a + b + c = 180

a + (a + 60) + (6a) = 180
8a + 60 = 180
8a = 180 - 60
8a = 120
a = 120/8
a = 15 <=== here is one angle

b = a + 60
b = 15 + 60
b = 75 <=== and another one

c = 6a
c = 6(15)
c = 90 <=== and the last angle
