Explain if this student has made a mistake. Explain what the mistake was and how you would fix it. include the right answer

Mistake =>

How it can be fixed =>

(correct answer)

Step-by-step explanation:

The student solved the problem correctly up to the second step where 6 was added to both sides of the equation.

The mistake he made was in his division.

Thus, instead of dividing both sides by 8, he divided both sides by 4, which is incorrect.

Mistake =>

How it can be fixed =>

(correct answer)

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
