Answer:
90 km/h
Step-by-step explanation:
To solve this problem you first need to convert minutes to hours since the unit is km/h. Doing this we get half an hour (1 hour=60 mins so you divide 30 by 60) after converting you simply divide 45 by 1/2 or .5 to get the answer.
Its c.
If you will substitute those numbers to the pair of equations, both will be true.
1=-3+4
1=3-2
Step-by-step explanation/answer:
Order the numbers from least to greatest!
72, 74, 76, 78, 80, 82, 92, 92
Then calculate the median
First off, What is a median?
The median would be the middle number in the set of numbers
In this case the median would be 79 but let me explain
72, 74, 76, 78, 80, 82, 92, 92,
We cross out every small and greater number from this set until you are left with a number in the set
Thus, the only two left numbers are 78 and 80
Therefore we have to add 78 and 80 then divided by 2
Answer: 79
