Answer:

8 kilometers per hour.

Step-by-step explanation:

1-If you multiply the hours of the trip back (which is 4 hours) and the kilometer per hour (6 km/h) you will get 24.

2-Do the same thing with the trip there and you will get 3 hours multiplied by *blank* equals 24.

3-the blank is 8 kilometers per hour. And I wrote equal 24 to mean that the distance to Guam was 24 kilometers.

A runner is participating in a 10.3 mile race. If the runner stopped at a water station that is twice as far from the starting l
Rudik [331]
We have the representation of this problem in the figure below. As we have a 10.3 mile race, then the equation is fulfilled as:

d = 10.3mi =  d_{1}+ d_{2}

We know that there is <span>a water station that is twice as far from the starting line as from the finish​ line, then:

</span>d_{2}=2d_{1}

So:

d_{1} +2d_{1}=10.3
∴ d_{1}=3.43mi

and d_{2}=2(3.43)=6.86mi

<span>Finally, the distance of the runner from the finish​ line is:
</span>
6.86mi

Combine like terms
vredina [299]
Lets write this out:-

z² + z + 4z³ + 4z²

z² will become 1z² because when ever there is a varaible, and before it there is NO coefficient the coefficient automatically becomes 1. Same is with z. z will be come 1z.

Lets write it out again:-

1z² + 1z + 4z³ + 4z²

Combine like terms:- 

1z² + 1z + 4z³ + 4z²
(1 + 4)z² = 5z²
1z + 5z² + 4z³

So, when combining like terms in z² + z + 4z³ + 4z² the answer is
1z + 5z² + 4z³.

Hope I helped ya!! xD
