0.2(6x+1)/3.6=0.5x/9
Solution
(1.2x + 0.2)/3.6 = 0.5x/9
Cross multiplying, we get
9(1.2x + 0.2) = 3.6 * 0.5x
10.8x + 1.8 = 1.8x
10.8x - 1,8x = -1.8
9x = -1.8
Dividing both sides by 9, we get
x = - 0.2
That's the answer.
Thank you.

Step-by-step explanation:
Plan A: 10 CDs costs $2.30, so 1 CD cost $0.23
Plan B: A package of 50 CDs cost $10.5, so 1 CD cost $1.05
0.23 < 1.05
Choose Plan A
Hello,
Why "Multiply the polynomial by distribution" ?
It's s t u p i d, you compliquate the equation.
In order to find the roots of P(a)=(a-3)(a²+2a-6)=0
a²+2a-6
=(a²+2a+1)-7
=(a+1)²-7
=(a-√7)(a+√7)
P(a)=(a-3)(a-√7)(a+√7)
Roots are 3,√7 and -√7
(If i have well understood the question , sorry if not)
