z + 8 +3z is less than or equal to -4 for z

6x<3x+15 for x

-3x + 2.5x is less than or equal to 1.5(x+4) for x

-0.25 + 1.75x < -1.75+2.25x for x

x-6<6 and x+4 is greater than or equal too -1?
a: 2
b:14
c: 12
d: -6

( I just need if that's a,b,c or d)

and last

s + 4 <1.5 OR 3+x is greater than or equal to 7




Thanks for the help DDDDD

z+8+3z </= -4
(-8) (-8) subtrace
z+3z </= -12
(3) (3) divide
z </= -4


It might be the other way around as in z >= -4 im not that good with inequalities


that's the only one ill do I have a life too you know
