There is an error in the student's work, the remainder should be 10

<h3>Further explanation </h3>

The division operation is one of the basic arithmetic operations

Common signs used are \large{\boxed{:}}} or \large{\boxed{\slash}}

The division is written by placing the numerator above the denominator with a horizontal line between them or use a slash with the numerator's position and the denominator is parallel

The division is actually an iterative subtraction operation (as many as the number of divisors)

Division is the opposite of multiplying

The general form of division can be stated by:

\large{\boxed{\bold{divident:divisor=quotient+remainder}}

example:

7: 3 = 2 + 1

  • 7 = dividend
  • 3 = divisor
  • 2 = quotient
  • 1 = remainder

Division operation statement:

"7 divided by 3 equals 2 remainder 1 "

The form of division can also be expressed in terms of fractions

In the example above, the form of mixed fractions  :

\displaystyle \frac{7}{3} =2\frac{1}{3}

Mixed fractions consist of whole number and proper fractions

From the task

(see also the attached image)

When dividing 878 by 31, a student finds a quotient of 28 with a remainder of 11.

Division operation statement:

"878 divided by 31 equals 28 remainder 11

Arithmetic operations :

878 : 31 = 28 + 11

  • 878 = dividend
  • 31 = divisor
  • 28 = quotient
  • 11 = remainder

Because Division is the opposite of multiplying , so we check the solution with multiplying

divident - (divisor x quotient) = remainder

878 - (31 x 28) = 11

878 - 868 = 11

10 ≠ 11

So students make mistakes in subtraction operations,remainder should be 10

a system of equations is graphed here. which system of equations does the graph represent? A) y = 3x + 2y = -2x + 5 B) y = 3x -
n200080 [17]

Notice that the line with negative slope has a y-intercept of 5 and the line with positive slope has a y-intercept of 2.

On the other hand, the slope of the line with negative slope is -2, while the slope of the line with positive slope is 3 (This can be identified since in one case, the value of y decreases by 2 for each increase of 1 unit in x, and in the other, the value of y increases by 3 for each increase of 1 unit in x).

Using the y-intercept form to represent each line, the system of equations represented by the graph must be equivalent to:

\begin{gathered} y=-2x+5 \\ y=3x+2 \end{gathered}

From the given options, the one that displays the correct system of equations is option A.

Therefore, the answer is:

\begin{gathered} A) \\ y=3x+2 \\ y=-2x+5 \end{gathered}
