DIA [1.3K]

Answer:

  1. 5x+3
  2. x -7
  3. -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

_____

<em>Additional comment</em>

Note that swapping the order of operands in a subtraction problem (problems 2 and 3) will cause the sign of the result to reverse.

1 25% of what number is 13?
nasty-shy [4]

Step-by-step explanation:

Let 25% of x be 13

\therefore \:  \frac{25}{100}  \times x = 13 \\  \\ \therefore \:    \frac{1}{4}  \times x = 13 \\  \\ \therefore \:   x = 13 \times 4 \\  \\  \therefore \:  x =  52

Hence, 25% of 52 is 13.
