(-1/3x + 9.5) + x(3/4+2.5)
Kobotan [32]

Answer:

35x + 114

12

Step-by-step explanation:

(-1/3x + 9.5) + x(3/4 + 2.5)

(-1/3x + 95/10) + x(3/4 + 25/10)

(-x/3 + 5 × 19/2 × 5) + x(3/2² + 5²/2 × 5)

(-x/3 + 19/2) + x(3/2² + 5²⁻¹/2)

(2(-x) + 3 × 19/ 3 × 2) + x(3/2² + 5/2)

(-2x + 57/3 × 2) + x(3 + 2 × 5/2²)

-2x + 57/3 × 2   +  x(3 + 2 × 5/2²)

-2x + 57/3 × 2   +  x(13/2²)

-2x + 57/3 × 2   +  x × 13/2²

-2x + 57/3 × 2   +  13x/2²

2(-2x + 57) + 3(13x)/3 × 2²

2(-2x + 57) + 3 × 13x/3 × 2²

2(-2x + 57) + 39x/3 × 2²

(-2 × 2x + 2 × 57) + 39x/3 × 2²

(-4x + 114) + 39x/3 × 2²

-4x + 114 + 39x/3 × 2²

-4x + 39x + 114/3 × 2²

35x + 114/3 × 2²

35x + 114/3 × 4

35x + 114/12
