The answer is a
Answer: 1. X+2
2. 6x-3
3. -2x-1
4. 9x5
Step-by-step explanation:
1. X+4-3+1 There is only one variable, so you don’t need to worry about that. Just do all of the numerical operations. 4-3+1= 2. So it would be x+2
2. X-5+5x+2. Again, do the numerical operations first. -5+2=-3. X+5x=6x. So it would be 6x-3.
3. 2x+7-4x-8. 7-8=-1. 2x-4x=-2x. So it would be -2x-1.
4. (4+3)x+2x-5. Do the operation in the parenthesis first. Then it would be (7)x or just 7x+2x-5. Simplify to 9x-5.
Answer:
2.150 = 2.15
2 +15/10 > 2.15
2 + 0.015 < 2.15
215/100 = 2.15
Step-by-step explanation:
2.150 = 2.15, because 2.15 can be rewritten as 2.150.
2 +15/10=2+1.5=3.5
2 +15/10 > 2.15
3.5 > 2.15
2 + 0.015 < 2.15
2.015 < 2.15
215/100 = 2.15
2.15 = 2.15
