Speed = distance / time
3 hours 45 minutes = 3.75 hours
80 = distance / 3.75
distance = 80 * 3.75 = 300 kms Answer
3p-7+p=13 ok so you will want to add 3p to 1p if there's only a variable then there a invisible 1 in front of it so you'll add 3 to 1 wich is 4 so now your problem Is now 4p-7=13 you then make the negative 7 to a positive 7 so now your going to add 13+7 wich equals 20 now you divide 20 by 4 wich gives you 5
For this problem, let x be the number of children and y for adults. Formulate the equations: 1st equation, x + y = 3,200 and 2nd equation 5x + 9y = 24,000. Re-arrange 1st equation into x = 3200 - y. Then, substitute into 2nd equation, 5(3,200-y) + 9y = 24,000. Then, solve for y. The 16,000 - 5y + 9y = 24000. Final answer is, y = 2000 adults went to watch the movie.
Bruh it clearly says 65 mph so that’s the answer
1.
In line with the test each person who came into interaction
with the infected person will become infected also. With this information, the
calculation would be: 9 people each day for 7days would be equivalent to 9 x 7
which equals 63 people.
2.
Here were 7 other people in the experiment if patient
zero is left out. If each person intermingled with 6 different people every day
in 7 days then the calculation would be: 7 people infected x 6 new people = 42
infected people each day
42 new people every day x 7 days = 294
infected persons.
