<span> 4x+7=5
subtract 7 on both sides
4x = -2
divide both sides by 4
x = -2/4
simplify
x = -1/2</span>
Half of 2 = 1 so 1 year apart . That means
80-1 = 79 years
1 and 13/100 i'm pretty sure
$20 x 4.75% = NC Sales Tax
$20 x 0.0475 = NC Sales Tax
NC Sales Tax = $.95
5/13 = 0.3846153846153846
or for short 0.384
3/10 = 0.3
so most likely 3/10 is bigger than 5/13
