valentina_108 [34]

Answer:

45 %

Step-by-step explanation:

Time left until Christmas = 2 weeks

= 2 * 7 days [since 1 week = 7 days]

= 14 days

Number of days in December = 31

Percentage of the month left before Christmas = $\frac{Time left until Christmas}{Number of days in December} * 100$

= $\frac{14}{31} * 100$

= 0.45 * 100

= 45 %

Solve for x in the equation 2x2-5x+1=3

Butoxors [25]

2x^2 - 5x + 1 = 3

Subtract 3 from both sides
2x^2 - 5x + 1 - 3 = 3 - 3

2x^2 - 5x - 2 = 0

Use quadratic formula with A = 2, B = - 5, C = - 2

x = - b +- sqrt b^2 - 4ac/2a

x = - ( - 5) +- sqrt (- 5)^2 - 4(2)( - 2)/(2)(2)

x = 5 +- sqrt 41/4

x = 5/4 + 1/4sqrt 41 or x = 5/4 + - 1/4 sqrt 41

Answer: x = 5/4 + 1/4 sqrt 41
x = 5/4 + - 1/4 sqrt 41
