Answer:
B) {x| x<-12 or x>-6}
Step-by-step explanation:
-2/3x>8
change -2/3 as -3/2 and multiply both sides by -3/2x
-2/3x•(-2/3)x<-3/2•8
calculate
reduce
x<-3•4
multiply numbers
-----------
x<-12
-----------
now we're done with the first equation, let's do the other equation to find the answer!
-2/3x<4
multiply both sides by -3/2 and again change -2/3 by -3/2
-3/2•(-2/3)x>-3/2•4
calculate
reduce
x>-3•2
multiply numbers
----------
x>-6
----------
Answer:
3rd choice
Step-by-step explanation:
Add 6 to both sides to get 5x >= 15, or x >=3. This is the 3rd choice.
That would be 449 because if you divide them you will get it. So 5*4=20//22-20=2//take down 4=24.//5*4=20//24-20=4//take down 5=45//5*9=45//45-45=0// so that's why it's 449
