At a middle school 30% of the students walk 12.5% are dropped off by car and the remaining take the bus
If there are 800 students who attend this school how many students use each form of transportation

240 walk, 100 are dropped off and 460 take the bus.

Step-by-step explanation:

first, find the bus percentage by subtracting 30 and 12.5 from 100 (which is 57.5%)

now put these percentages in decimal form: 30 -> .30 and 12.5 -> .125 and 57.5 -> .575 and multiply them (separately to 800)

.30 x 800 = 240

.125 x 800 =100

.575 x 800 = 460

1,918

step-by-step explanation:

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.
