Pouvez-vous trouvez quatre nombre entier consécutif dont la somme vaut 1254 Et merci à vous

312.5, 313.5, 314.5, 315.5

Step-by-step explanation:

n + (n + 1) + (n +2) + (n+3) = 1254.

Solving gives, 4n + 6 = 1254.

1254/4 = 313.5 as our n.

Substituting for our n's: 313.5 + 313.5 + 1 + 313.5 + 2 313.5 + 3 =

312.5 + 313.5 + 314.5 + 315.5.

Check:

312.5 + 313.5 + 314.5 + 315.5 = 1254.

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.
