D is the answer for equivalent
Answer:
a=-24
Step-by-step explanation:
a/-6+8=12
subtract 8 from both sides
a/-6=4
multiply each side by -6
a=-24
The third one because 2(15+5)=2(20)=40
Answer:
Step-by-step explanation:
lm=6x+3
mn=4x-17
ln=x+14
lm+mn>ln
6x+3+4x-17>x+14
10x-14>x+14
9x>28
x>28/9
mn+ln>lm
4x-17+x+14>6x+3
5x-3>6x+3
-x>6
x<-6
lm+ln>mn
6x+3+x+14>4x-17
7x+17>4x-17
3x>-34
x>-34/3
combining x<-6 or x>28/9
It’s A bc 228/3 is 76 and the rest of the answers seems like it wouldn’t be the correct answer.(I apologize if I’m wrong)
