2l+2w=perimeter <= equation for perimeter
<span>w+4=l <=length is 4 greater than width </span>
<span>2w+2(w+4)=24 <= plug in the l in the first equation with the second equation </span>
<span>2w+2w+8=24 <= solve the equation </span>
<span>4w=16 </span>
<span>w=4 </span>
<span>and, since </span>
<span>w+4=l <= length is 4 greater than width </span>
<span>then l=4+4 </span>
<span>l=8</span>
To figure out which airline provides more reliable service, we need to figure out what ABC Airlines's delays are in percents.
To get that, we need to reduce 18/126 by 2.
When we reduce both the numerator and the denominator we get 9/63.
Now, we cannot reduce that again, without getting a decimal for the numerator/denominator.
So, now that we know that the fraction is 9/63, we divide it, and we get :
<span> 0.142857
</span>
Changing that into a percent, we get 14%.
14% is the percent that ABC Airlines has delays.
DEF Airlines has delays of 13% in recent flights.
So, from that, we can conclude that DEF gives more reliable service.
Unfortunately, Katie will be $20 short
She has $40
Plus the $38 x 5 she will be earning which is $190
$190+$40 is $230
Looks like Kate needs one more day of hard work to get her bike ; )
