X=7 All you need to do is combine like terms and then move the appropriate terms to the appropriate side.
Answer:
7
Step-by-step explanation:
So, we know that this process happened 3 times in total. The original amount of kids we can call x, so the next wave filled in the gaps inbetween, so we call that amount x-1, the next wave would be (x+x-1)-1 or 2x-2, and the last would be 4x-4
adding this all up we get 8x-7=49, so 8x = 56 or x = 7

Bob travels within the speed limit.
For Bob to travel within the speed limit, the distance travelled by Bob in 3 hours must be less than the distance travelled gotten from the equation y = 70x.
<h3 /><h3>Maximum distance in 3 hours from the equation</h3>
With x = 3, y = 70(3) = 210 miles.
<h3>
</h3><h3>
Bob's distance in 3 hours</h3>
From the straight line graph, Bob travels, 200 miles in 3 hours.
<h3 /><h3>Conclusion</h3>
Since this distance is less than that gotten from the equation, Bob travels within the speed limit.
So, Bob travels within the speed limit.
