Answer:
This has 2 solutions
Step-by-step explanation:
This question has 2 solutions because the answers can be x=1 and x=-4 because 5-8=-3 and you can get 5 with a absolute value and 5-8=-3
Step-by-step explanation:
4 balls = 344
7 balls = 7×344/4= 602
So, 4 x 3 is 12, so 4 blades cost 79.74 x 3 (because every turbine has 3 blades each) is 318.96
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.
