Hi!
Alrighty, so there are 5 sets of 50 in 250 (250 divided by 50), so just take 50 times 12 and get 60! Hope that helped :)

Question 1 is 60 because 50 times 5 is 250 so then 12 times 5 is 60, so there would be a total of 60 channels with commercials on. Question 2 the answer is 9 because 100 times 3 equals 300 and 3 times 3 equals 9, so there would be a total of nine shows rescheduled.

Beyonce is solving a system of equations: 2x - 3y = - 2 and 4x + y = 24 She multiplies the second equation by 3 and then adds th
zmey [24]

Answer:

Yes, Beyonce will get the same solution.

Step-by-step explanation:

The given system is

2x - 3y = - 2

and

4x + y = 24

If she multiplies the first equation by -2 , she gets,

-4x+6y=4

4x + y = 24

Adding the two equations gives

7y=28

This means y=4

When we put y=4 into the bottom equation we get:

4x+4=24

4x=20

x=5

Therefore Beyonce will still get x=5, and y=4 as solution.
