Answer:
Paul is wrong.
Step-by-step explanation:
He did not add the exponents right in this equation. The right answer would be 5.67 * 10^9.
I hope this helped. : )
3(x−5)/2=2(x+5)/3
Cross-multiply.
(3(x−5))/2=(2(x+5))/3
3(x−5)*(3)=2(x+5)*(2)
9x−45=4x+20
Subtract 4x from both sides.
9x−45−4x=4x+20−4x
5x−45=20
Add 45 to both sides.
5x−45+45=20+45
5x=65
Divide both sides by 5.
5x/5=65/5
x=13
600 becuase 90/.30= 300 and 300*2 =600
