Charlotte earned a grade of 84% on her multiple-choice math final that had a total of 200 problems. How many problems on the final exam did Charlotte get wrong?

Wrong problems = 32

Step-by-step explanation:

Total no of problems = 200

Charlotte earned a grade of 84% on her multiple-choice.

Correct problems,

Wrong problems = 200 - correct problems

= 200 - 168

= 32

Hence, there are 32 problems on the final exam Charlotte get wrong.

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.
