Which explains whether or not this model accurately shows 13 × 3?
it does because 13 = 10 + 3, and the model shows 3 groups of 10 and 1 group of 3.
it does because 13 = 10 + 3, and the model shows 3 groups of 10 and 3 groups of 1.
it does not because 13 = 10 + 3, and the model should show 1 group of 10 and one
group of 3.
it does not because 13 = 10 + 3, and the model should show 3 groups of 10 and 3
groups of 3.

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8

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.
