Answer:
25
Step-by-step explanation:
5(n-8)=3n+10
5n-40=3n+10
5n=3n+50
2n=50
n=25
54:84___(÷2)
27:42___(÷3)
9:14
235/100=2.35 (I didnt know if you wanted the answer so i just put it down)
(divided)
Y=-x
(X,Y) will change to -> (-y,-x)
(5,-3) will change to ->(3,-5)
-3 changed to 3 because -(-3) = 3
So the answer is (3,-5). I recently learn about this one too.
Answer:
-127.488°
Step-by-step explanation:
45" is 0.75 of 1', so -128° 30' 45" = -128° 30.75'
Next: 30.75' is 30.75/60 of 1°, and or -128° plus 0.5125 of 1°.
The final answer is found by adding 0.5125° to -128°:
-128.0000°
+ 0.5125°
--------------------
-127.4875
To the nearest thousandths of a degree, that would be -127.488°
