4/7 is the same as 4 divided by 7. When you do that you get a really long decimal, I made sure I was right by using a calculator and multiplying that by 35 to get 20.

Hope that helps and have a great day!

Answer:

x = 9

m Angle B = 54

m Angle E = 54

Step-by-step explanation:

As m Angle B and m Angle E are congruent,

5x + 9 = 7x - 9

-2x = - 18

x = 9

m Angle B = 5x + 9 = 54

m Angle B = m Angle E

Therefore, m Angle E = 54
