Answer: -7/5
Step-by-step explanation:
x = - 5cm^2 - 7m^2 + 35/ m (5c - 7), C = (cross out the equal sign) 7/5 and m = (cross out the equal sign) 0 and n = -7/5
Answer:
Number of Possible Sequence = 5 x 4 x 3 x 2 x 1 = 120 ways

Answer:

Step-by-step explanation:
We have been given that in a recent year, 304 of the approximately 300,000,000 people in the United States were struck by lightning.




Therefore, the probability that a randomly selected person in the United States will be struck by lightning this year is
.
Answer:
guess and check
Step-by-step explanation:
Linear equation systems usually have two or more variables to find.
The values for these variables can be found by different methods, some of them are indeed graphing, substitution and with matrices.
So these are correct options that are used to solve linear systems of equations.
On the other hand, the guess and check method is not used to find the solution of these systems, since the more variables the system has the more difficult it is to guess the answer,<u> the graphic and mathematical methods are more effective and reliable.</u>
