Answers

Answer 1
Answer:

Answer:

u = t/18 - 5

Step-by-step explanation:

45n + 18u = t where t is the total price, n is the number of new video games, and u is the number of used video games

plug in two:

90 + 18u = t

solve in terms of u:

18u = t - 90

u = t/18 - 5

Answer:

1/12

Step-by-step explanation:

First, find common denominators. Note that what you do to the denominator, you must do to the numerator.

(3/4)(3/3) = 9/12

(2/3)(4/4) = 8/12

Subtract:

9/12 - 8/12 = 1/12

1/12 is your answer.

Answer:

1/12

Step-by-step explanation:

(3)/(4) - (2)/(3) \n \n = (3 * 3)/(4 * 3) - (2 * 4)/(3 * 4) \n \n = (9)/(12) - (8)/(12) \n \n = (9 - 8)/(12) \n \n = (1)/(12) \n

What is the positive solution of x2 – 36 = 5x?

Answers

The equation x^2 - 36 = 5x is a quadratic equation and can be solved thus: x^2 - 36 = 5x x^2 - 5x - 36 = 0 x^2 + 4x - 9x - 36 = 0 x(x + 4) - 9(x + 4) = 0 (x - 9)(x + 4) = 0 x - 9 = 0 or x + 4 = 0 x = 9 or x = -4 Therefore, the positive solution of x^2 - 36 = 5x? is 9.

short answer is 9 for anyone who wants it.

Yes the full answer is -4, 9 but the question asks for the POSITIVE SOLUTION so the answer is just 9
