This sentence is key: "At this point, he is 3 blocks from school and half way there"
<span>since 3 blocks is halfway of the trip, that means the total distance is 6 blocks </span>
<span>from the stoplight to the library must be one block, and one block took him 4 minutes </span>
<span>therefore, therefore, the total trip takes 4 * 6 = 24 minutes, or 4 * 3 = 12 minutes from the library </span>
<span>8:24 + 12 = 8:36 </span>
<span>he arrives at school at 8:36 </span>
<span>(and yes, make sure to sketch this out!)</span>
Answer:
It's not enough information. What's the question?
Step-by-step explanation:
Answer:
213
Step-by-step explanation:
u multiply first then add the rest ez
2^(1+2n)
2^(1+0) = 2
2^(1+2) = 2^3 = 8
2^(1+4) = 2^5 = 32
Answer:
and 
.
Step-by-step explanation:
So I believe the problem is this:
where we are asked to find values for 
and 
such that the equation holds for any 
in the equation's domain.
So I'm actually going to get rid of any domain restrictions by multiplying both sides by (x-3)(x+7).
In other words this will clear the fractions.
As you can see there was some cancellation.
I'm going to plug in -7 for x because x+7 becomes 0 then.
Divide both sides by -10:
Now we have:
with
I notice that x-3 is 0 when x=3. So I'm going to replace x with 3.
Divide both sides by 10:
So and .
