Solve. 3n-7+2n=8n+11
Bezzdna [24]
------------------------------------
<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

Find the distance between (-5,3) and (2,-1).
natali 33 [55]

Answer:

distance = sqrt( 65 ) ~= 8.06

Step-by-step explanation:

To find the distance between two points, we can use the distance formula.

distance = sqrt( [x2 - x1]^2 + [y2 - y1]^2)

distance = sqrt( [-5 - 2]^2 + [3 - -1]^2)

distance = sqrt( [-7]^2 + [4]^2)

distance = sqrt( 49 + 16 )

distance = sqrt( 65 ) ~= 8.06

Cheers.
