A television programmer is arranging the order that seven
movies will be seen between the hours of 6 P.M. and 8 A.M. Two of the movies
have a G rating, and they are to be shown in the first two time blocks . One
of the movies is rated NC-17, and it is to be shown in the last of the time
blocks, from 6 A.M. until 8 A.M. Given these restrictions the movie can be
arrange in:
2*1*4*3*2*1*1 ways = 48 ways
Answer:
2/3
Step-by-step explanation:
fraction of book already read = 1/3
fraction which represents whole book = 1 = 3/3
fraction of remaining book = fraction of whole book - fraction of book already read
= 1 - 1/3
= 3/3 - 1/3
= (3-1) /3
= 2/3
To solve a system of equation by elimination, the coefficients of the same variable of both equations must be equal. In this case, let's choose y.
In order to make the coefficient of y of the second equation be equal to 7, we divide it by 2. Resulting to:
2x - 7y = -34
Next, add the two solutions so that the y term is eliminated. The result is:
10x = 5
Then solve for x
x = 1/2
Substitute x to either of the solution to solve for y. The result is:
y = 5
