Select the following expressions. I will just list the letter choice:
A, C, D
Answer:
Step-by-step explanation:
1. 94/100=0.94=94%
2.15/20=0.75=75%
3. 4/10=0.4=40%
4. 3/100=x/100 》x=3
5. 80/100=x/30 》x=2400/100=24
6. 30/100=x/10 》x=3
7. 2/5=0.4=40%
8. 60/100=x/5 》 x=300/100=3
9. 50/100*x=150 》 50x=15000 》x=300
10. 3/5=0.6=60% 》 100%-60%=40%
Answer:
I got x<equal to -11 or x>equal to4
Step-by-step explanation:
x^2+15x+44=0
(x+4)(x+11)=0(Factor left side of equation)
x+4=0 or x+11=0(Set factors equal to 0)
x=−4 or x=−11
Check intervals in between critical points. (Test values in the intervals to see if they work.)
x<−11(Works in original inequality)
−11<x<−4(Doesn't work in original inequality)
x>−4(Works in original inequality)
Answer:
x<−11 or x>−4
