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.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

-6 is the correct option from the above given options
