Well it would be 70% of them because Jack had 100% and 30% minus 100% is 70%

The percentage would be 70%. The total amount of cards Jack has is 100%, since his brother took 30%, you subtract 100% by 30%. You’ll get 70%.

3+ (-9).<br>Should you add or subtract 3 and 9? Why?

You subtract because it's just adding a negative which cancels out the adding and makes it a subtraction problem.

nekit [7.7K]

Answer:

Step-by-step explanation:

$n-number,\ n>0\\\\9n^2+8=44\qquad\text{subtract 8 from both sides}\\\\9n^2+8-8=44-8\\\\9n^2=36\qquad\text{divide both sides by 9}\\\\\dfrac{9n^2}{9}=\dfrac{36}{9}\\\\n^2=4\iff n=\pm\sqrt4\\\\n=\pm4$
