When it comes to finding the percent of something, you simply divide the percent by 100 and multiply that number by the given amount, like so:
105*.17=17.85
$17.85

<span>Question:
</span>------------------------------------<span>
3n - 7 + 2n = 8n + 11
------------------------------------
Combine like terms:
</span>------------------------------------<span>
5n - 7 = 8n + 11
</span>------------------------------------<span>
subtract 8n from both sides:
</span>------------------------------------<span>
-3n - 7 = 11
</span>------------------------------------<span>
Add 7 to both sides
</span>------------------------------------<span>
-3n = 18
</span>------------------------------------
Divide by -3 on both sides:
------------------------------------
n = -6
------------------------------------
Answer: n = -6

Answer:
-186
Step-by-step explanation:
When you add a positive number to a negative, it gets bigger (In value) . For example:
-5 + 4 = -1
-10 + 12 = 2
So for this equation, -200 + 14, all you have to do is subtract 14 from 200, which will get you 186.
Since you removed the negative, add it back to get -186
Answer:
6
Step-by-step explanation:
We have to use Pythagoras' identity twice to find y
The square on the hypotenuse is equal to the sum of the squares on the other two sides.
In right triangle MUT to find TU
TU² + 3² = 6², that is
TU² + 9 = 36 ( subtract 9 from both sides )
TU = 27 ( take the square root of both sides )
TU =
=
= 3
In right triangle NUT to find y
y² = 9² + (3
)² = 81 + 27 = 108 ( take the square root of both sides )
y =
=
= 6
