User: One number is 3 less than twice another. If their sum is 39, find the numbers. Which of the following systems of equations represents the word problem? y = 2x - 3 and y = x + 39 y = 2x - 3 and x + y = 39 y = 2(x - 3) and x + y = 39

Weegy: x + 2x - 3 = 39 <==EQUATION 3x - 3 = 39 3x = 42 x = 14 2x - 3 = 25 14 and 25 <==ANSWERS Answer: B. y = 2x - 3 and x + y = 39

(27x^4 - 18x^3 + 9x^2) ÷ 3x
= (27x^4/3x) - (18x^3/3x) + (9x^2/3x)
= 9x^3 - 6x^2 + 3x

(12x^3 - 11x^2 + 22x - 5) ÷ (4x - 1)
= (12x^3/4x - 1) - (11x^2/4x - 1) + (22x/4x - 1) - (5/4x - 1)
= 3x^2 - 2x + 5

Factor completely, then place the answer in the proper location on the grid. 12a^2 - 36ab + 27b^2
Weegy: 12a^2 - 36ab + 27b^2 = 3(2a - 3b)^2 User: Subtract the following polynomials, then place the answer in the proper location on the grid. Write the answer in descending powers of a. Subtract: 16a 2 - 32a + 9 from 12a 2 + 60a - 8. User: Multiply the following polynomials, then place the answer in the proper location on the grid. Write the answer in descending powers of x. (8x + 3)(4x + 7) Weegy: (8x + 3)(4x + 7) = 32x^2 + 12x + 56x + 21 = 32x^2 + 68x + 21 User: Divide the following polynomials, then place the answer in the proper location on the grid. Write the answer in descending powers of a. Divide 5a^2 + 6a - 9 into 25a^4 + 19a^2 - a - 78. (More)

(12a^2 + 60a - 8) - (16a^2 - 32a + 9)
= (12a^2 + 60a - 8) + (-16a^2 + 32a - 9)
= -4a^2 + 92a - 17
