A13 and one fourth inch board is cut from a 38 and three fourths inch board. the saw cut takes three eighths inch. how much of the 38 and three fourths inch board is left after cutting?

There is 25 1/8 inches left

Step-by-step explanation:

We have a board that is 38 3/4 inches

We cut away 13 1/4

38 3/4

-13 1/4

25 2/4

The saw takes 3/8

25 2/4

-    3/8

Get a common denominator of 8   2/4 * 2/2 = 4/8

25 4/8

-    3/8

25 1/8

There is 25 1/8 inches left

Step-by-step explanation:

A 13 and one fourth inch board is cut and the saw cut takes three eighths inch. So total length from cut = 13 1/4 + 3/8 = 13 5/8 inch.

Original board is 38 and three fourths inch.

So after cutting, there is 38 3/4 - 13 5/8 = 25 1/8 inch left in the original board.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
