Answer:
We end up with our original number
Step-by-step explanation:
Let x be our number
We increase by 100
increase = old number * 100%
increase = x*1
increase = x
New number = old number + increase
= x+x
=2x
Now we decrease by 50%
decrease = number *50%
= 2x*.5
=x
Final number = new number - decrease
= 2x-x
=x
Answer:
14256
Step-by-step explanation:
- 10/100×15840=1584
- 15840-1584=14256
- Answer =14256
I think it's right and scalene
It's a right triangle because it has a right angle and it's a scalene triangle because it has three unequal sides.
Answer: 7
Step-by-step explanation:
Answer:
A and C
Step-by-step explanation:
By letting x = 0 she is eliminating the terms in x , rather than simplifying
A
9x - 3x - 4 ← collect like terms
= 6x - 4
B
12x - 4 ← already in simplest form
C
5x + x - 4 ← collect like terms
= 6x - 4
Thus A and C are equivalent expressions
