Use distrubutive property <em>a(b + c) = ab + ac</em>
6(5r - 4) - 2(r - 7s - 3)
= (6)(5r) + (6)(-4) + (-2)(r) + (-2)(-7s) + (-2)(-3)
= 30r - 24 - 2r + 14s + 6
= (30r - 2r) + 14s + (-24 + 6)
<h3>= 28r + 14s - 18</h3>

2.30 PM
Step-by-step explanation:
Olivia has a 1hr head start of Ben. While traveling at 55 mph she will have covered a distance of;
55 * 1 = 55 miles
Then Ben begins to travel at 65 mph which is
65 – 55 = 10 mph
Faster than Olivia.
This means that Ben will be closing in on the 55 miles head-start made by Olivia by 10 mph. To find out after how long Ben will completely close the gap;
55 / 10 = 5.5 hours
0.5 hours in minutes is;
5/10 *60 = 30 minutes
Ben will catch up to Olivia on;
9.00 + 5.30 = 14.30
= 2.30 PM

100 / 5 = 20
Substitute n with 20, and we get 5 * 20 = 100
So if 5n must be less than 100, then all we know is that n is under 20. But without more information, we can't determine exactly what n is. It could be anywhere between 0 and 19.
