Answer:
1/x-2/3=3/2x
-2/3=3/2x-1/x
-2/3=(3-2)/2x
-2/3=1/2x
by cross multiplication
-2(2x)=1(3)
-4x=3
x= -3/4

Answer: 6x, 5x, and 3 are the terms
Step-by-step explanation:
A term is any number that can be added or subtracted in an expression.
Answer:
4x^2−12x+9
Step-by-step explanation:
The form of a perfect square trinomial is ...
(a +b)² = a² +2ab +b²
The first and last terms must be positive and perfect squares. The middle term must be twice the product of their roots (possibly with a minus sign).
x^2 -10x -25 . . . . -25 is not a positive perfect square
4x^2 -12x +9 . . . . 12x = 2√(4x^2·9) = 2·6x . . . . perfect square
9x^2 +12x +16 . . . 12x ≠ 2√(9x^2·16) = 2·12x
16x^2 +16x +1 . . . 16x ≠ 2√(16x^2·1) = 2·4x
.45 is between 0.4 and 0.5
Answer:
Step-by-step explanation:
5/8x = 1/2x + 2
5/8x - 1/2x = 2
46x = 2
x=16
So you want to get x by itself so you. First you get 5/8x and 1/2 and subtract 1/2 from both sides. Then find the common demonantor for both numbers. After use inverse operations to multiply both sides by the reciprocal of the fraction coefficient. Finally check the solution by substituting 16 for x in the original equation.
