Hannah buys 2/3 pound of roast beef. she uses 1/4 pound to make a sandwich for lunch. how many roast beef does she have left

2/3 - 1/4

=> taking L.C.M of the denominators we get,

=> 8/12-3/12

=> 5/12 is left with her,, ;)

HOPE THIS HELPS YOU...;)

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

1 is c

2 is a

3 is a
