Answer: 15v
Step-by-step explanation:
It is wrong because 14/24 should convert to 1/2 not 7/12
25% = 5 dollars 75%= 15 dollars and 125%= 25 dollars
X=9 beecause 135-20 =115 and 130 is bigger than 130
28. 6x+42-20=6x
42-20=0
42-20 gives you 22
22=0
Statement is false
30. -2x-4=-2x-3-1
-2x-4=-2x-4
Statement is true because both sides are identical
32. 2x+8-5=2x+3
8-5=3
3=3
Statement is true for any value of x
34. 3x+(x+4)=18
3x+x+4=18
4x+4=18
4x=18-4
4x=14 (next divide both sides by 4)
x= 7 over 2
7/2
