What number should be placed in the box to help complete the division calculation? (1 point) Long division setup showing an incomplete calculation. 15 is in the divisor, 7978 is in the dividend, and 5 hundreds and 3 tens is written in the quotient. 7500 is subtracted from 7978 to give 478. An unknown value represented by a box is being subtracted from 478.

Step-by-step explanation:

Given the long division setup :

Divisor = 15

Quotient = 5 hundreds and 3 tens

Dividend = 7978

7500 subtracted fromn7978 to give 478

Find the unknown number subtracted from 478

Explanation:

The coefficients of the equations help fill out the majority of the matrix. The column at the far right end is composed of the right hand side values of each equation.

For instance, the equation , which is really the same as will have the coefficients 3,-5,1 and the right hand side value 14 all be written in the first row of the answer matrix. The other equations form the other two rows. The order of the rows and columns is important.
