12oz gold and 20oz silver
The answer is −<span><span>28<span>x^8</span></span><span>y^5</span></span>
4.2 x 10^<span>-3 is the answer</span>
First you should add -7 on both sides of the equation so you will have:
5b = -23 -7 ⇒ 5b = -30
now you should divide both sides by 5:
b = -30/5 ⇒ b = -6 :)))
i hope this is helpful
have a nice day
