Y=6x+4 is the expression you will use
Basically, choosing one red marble out of everything is 3 / 10 because there are 3 chances of picking the red marble and 10 marbles overall. Picking one blue marble would be 6 / 10, or 3 / 5. You would multiply these two probabilities together because they are independent of each other:
(3 / 10)*(3 / 5) = 9 / 50
The probability is 9 / 50.
<span><span><span>(3x−2)/</span><span>(x−1<span>)^2</span></span></span>=<span>A/(<span>x−1) </span></span>+ <span><span>B/x</span><span>(x−1<span>)^2
</span></span></span> =[<span><span>A(x−1)+Bx</span><span>(x−1<span>)] / 2</span></span></span></span>
3x-2=A(x-1)+Bx
3x-2=x(A+B)-A
A+B=3
-A=-2=>A=2
A+B=3=>2+B=3=>B=1
lets check our partial fraction
we have

Answer:
552.5
Step-by-step explanation:
2/5x + 68 = 289
2/5 x = 289 - 68
2/5x = 221
x = 221 * 5/2 = 552.5
I hope im right!!!
