No. A unit rate would be something like 6 2/3 miles per hour, which is the same speed as above.
First, let's break the worded equation up into two parts:
- "<span>4 times a number less than 6'
This is 4 * (6-x)
- "</span><span>8 more than twice that number"
This is 2x+8
Now combine these two expressions:
</span>4 * (6-x) = 2x+8
4 * (6-x) = 2 * (x+4)
2 * (6-x) = x+4
12-2x = x+4
-3x = -8
x = 8/3

Answer:
D
Step-by-step explanation:
elves in 1000 years = elves now x (rate of increase)^time
elves increase every century. there are ten years in a century. thus time = 1000/100 = 10 years
144 x (3)^10 = 8,503,056 elves
<span> x = 4
x = -4<span>
x= 0.0000 - 1.4142 i
</span><span> x= 0.0000 + 1.4142 <span>i </span></span></span>
