Answer:
Ms D left at 6:40 AM
Step-by-step explanation:
Given:
MS D arrived at school at 7:30 AM
time spent for dinner = 35 mins
Time taken to to go to school = 15 mins
We will first find the Total time taken after leaving.
Total time taken can be calculated by adding time spent for dinner and Time taken to to go to school.
Total time taken after leaving = time spent for dinner + Time taken to to go to school = 35 +15 = 50 mins
MS D arrived at school at 7:30 AM.
Hence Time Ms D left = Time She arrive at school - Total time taken after leaving = 7 hrs 30 min - 50 mins = 6 hrs 40 mins.
Hence Ms D left at 6:40 AM.
Answer:
One. It is a = 7/3
Step-by-step explanation:
Let's simplify the equation 6a − 3a − 6 = −2 + 3 by combining like terms:
3a - 6 = 1
Adding 6 to both sides, we get:
3a = 7.
Dividing both sides by 3, we get
a = 7/3.
This equation has ONE solution, which is a = 7/3.
