Answer:
x=1
Step-by-step explanation:
3(x+1)=-2(x-1)+6
1) Distribute 3 to x and 1:
3x+3=-2(x-1)+6
2) Distribute -2 to x and -1:
3x+3=-2x+2+6
3) Combine alike terms:
3x+3=-2x+8
4) Add 2x to both sides:
5x+3=8
5) Subtract 3 from both sides:
5x=5
6) Divide both sides by 5:
x=1
Answer:
-17(-)-18=-17+18=1 or -17+18=1
Step-by-step explanation:
if -17 is one number you Add 18.
-17(-)-18=-17+18=1
77+72=149
149/2=74.5
through the process of elimination, I found that Jim needs to get an 88 or higher to receive an average of 79 or greater.
77+72+88=237
237/3=79
