Sandra has 828 math worksheets to do in class and her friend kayla has 828 work also how many does they have in all ?

1656 worksheets

Step-by-step explanation:

To find a total, we need to add Sandra's worksheets and Kayla's worksheet. Let x be the total of worksheets.

828+828=x

Add them up

1656=x

They have a total of 1656 worksheets.

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.
