WILL GIVE BRAINLIEST! Estimate the following sum using front-end estimation. 48.1 + 29.7 + 11.8

O 70

O 80

O 90

O 100

90

Step-by-step explanation:

If you add all those together than you get 89.6 which equals to 90 if estimating. no need for an explanation

Only add those numbers up and round

80 is your answer i think

Step-by-step explanation:

Sorry if 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.
