What you want to do is isolate the variable. Take your equation 3u=14-4u and move the -4u over to the other side; making it look like this 7u=14. Then divide by 7 to isolate the u making u=2. Your answer is u=2.
The length of segment of EF would be 16
Answer:
![3^{\frac{7}{10} }](https://tex.z-dn.net/?f=3%5E%7B%5Cfrac%7B7%7D%7B10%7D%20%7D)
Step-by-step explanation:
= 3^1/2 x 3^1/5 = 3^(1/2 +1/5) = 3^7/10
Answer:
Last option is the correct answer.
Step-by-step explanation:
By sine rule..

Answer: 5
Steps:
5x - 2y = 30
5(8) - 2y = 30
40 - 2y = 30
-2y = 30 - 40
-2y = -10
y = -10/-2
y = 5
I would appreciate the brainliest if this answer was correct and the steps were clear and helpful! :)
