Answer:
x=amount invested at 7%
2x=amount invested at 8%
3x=amount invested at 9%
interest=principal*rate*time (time=1 year)
$150=0.07x+0.08*2x+0.09*3x
$150=0.07x+0.16x+0.27x
$150=0.50x
$1500=5x
x=$300 invested at 7%
2x=$600 invested at 8%
3x=$900 invested at 9%

Answer:
The prime factorization of 891 is 9^2*11
Step-by-step explanation:
Divide 891 by 9, 9, and finally, 11. Or use a factorization calculator.
The function representing the price of the ring x years after 2000 is f(x) = (100 + 35)/100 *x + 590 = 135/100 *x + 590 = 1.35x + 590
i.e. f(x) = 1.35x + 590
(r+b-g)(b-g)
I this question , we have the values of r,b and g given , which are r=9,b=5,g=6
And we have to find the value of the given expression . And for that we need to substitute the values of r,b and 9 in the expression. That is ,
(9+5-6)(5-6) = 8(-1) = -8
So the value of the given expression is -8.
