Answer:
The answer should be C) 4x + 5x = 180
Step-by-step explanation:
Let x be total hours of battery life. We have been given that battery life of Vera's phone is down to 2/5. So remaining battery life,

We have been also given that it drains another 1/9 every other hour. Now let us substitute our given information into an equation.

Now we will solve for x.


Let us convert 2/5 into minutes. We know 1 hour has 60 minutes.

Therefore, remaining battery life will be 5 hours and 24 minutes.
Answer: yes
Step-by-step explanation:
Jim- 60× .45= 27
Dora- 10 of the 60
Ada- 60× .25= 15
Kim- 8 remaining
Jim placed the most with 27
The Triangle Sum Theorem states that the sum of the angles of a triangle equal 180°.
Therefore,
45° + 62° + k = 180
107° + k = 180
k = 73°
The value of k is 73°
