Answer:
- 5x+3
- x -7
- -x +7
Step-by-step explanation:
Combine like terms. The associative and commutative properties of addition apply, as does the distributive property.
__
1. (2x+5)+(3x-2) = (2x +3x) +(5 -2) = 5x +3
__
2. (3x-2)-(2x+5) = 3x -2 -2x -5 = (3x -2x) +(-2 -5) = x -7
__
3. (2x+5)-(3x-2) = 2x +5 -3x +2 = (2x -3x) +(5 +2) = -x +7
_____

Note that swapping the order of operands in a subtraction problem (problems 2 and 3) will cause the sign of the result to reverse.
Answer:
9.8 X 10^-07
Step-by-step explanation:

If we ask 500 individuals whether they have credit card and if we consider the probability of people having a credit card being normally distributed, then we assume that, considering 30% do not have a credit card, everyone who is within 1SD of the mean will have a credit card, while the remaining ~15% on either tail of the distribution do not.
