We move all terms to the left:
+31x+32)-((+5)=0
So your answer is 0
1) 23
2) 3
3) 6x+5 (I am not sure what they ask for)
4) -12+x
5) -56x + 16
6) -90+80x
7) -18x+45y-27
8) 6x+24y-42
9) 2/3w+x-1
10) -1.2wy +3y
Answer:
perimeter = 1 3/4
Step-by-step explanation:
1. 3/4 x 2 because there are two sides with the fraction 3/4. 3/4 x 2 is 1 1/2
2. 1/8 x 2 because there are two sides with the fraction 1/8. 1/8 x 2 is 1/4
3. 1 1/2 + 1/4 = <u>1 3/4</u>
Answer:
