8m+27= 2m-3
take 2m and subtract it from 8m, this gives you 6m. now your equation is 6m+27=-3.
subtract 27 from -3, this will make it 6m=-30.
divide 30 by 6. this gives you your answer. m=-5, because -30 divided by 6 equals -5.
now to test it you can plug -5 into the equation in place of M. 8 times -5 equals -40, plus 27 equals -13. 2 times -5 equals -10 plus -3 equals -13.
Answer:
1080°
Step-by-step explanation:
formula to find the sum of interior angles of a polygon is (n-2)×180
octagon has 8 sides so n=8
(8-2)×180
6×180
=1080°
Answer:
+
Step-by-step explanation:
We sure can write 2^2/5+ 3^1/10 as 
// use the
to transform the expression
Convert
to
=
(here a = 2, n = 5, m = 2)
Then convert
to
=
(here a = 3, n = 10, m = 1)
Now we get
=
+
. This is the simplified form, which is the answer.
Subtract 3t from the equation to get 2t=-7. Multiply by three to find that 6t=-21.
