12 and 28, because
n + (<u><em>2n + 4</em></u>) = 40
<u><em>3n + 4</em></u> = 40
<em><u>3n = 36 n = 12</u></em>
<u><em>12x2 + 4 = 28</em></u>
<u>28</u> is the larger number.
$4
You round it to the nearest dollar which would be 20 and then 20% of $20 is 4
Ok, so the set up would be 3x+8 = 5x-40. If you solve for x you can then enter it into the equation and get your answer.
So subtract 3x from 3x and 5x. That leaves you with 8 = 2x-40
Next, you add 40 to both sides leaving you with 48 = 2x
Now divide 2 from x and 48 which give x = 24
Enter the value of x into the equation 3x+8
3(24)+8
80
And because we know it is an acute angle, angle ABC = 80 degrees
X = 34
<span>2+8-x=-24
</span>Add 2 + 8: 10-x=-24
Subtract 10 from each side: -x = -34
Change the signs from each side: x = 34
