4:3 =8:?
Answer: 8:6
so 6 would be correct
3x-8+6x=7
9x-8=7
9x=15
x=9/15
x=3/5
It is 150 degrees. This is due to the fact that all angles across from each other in this way are equal. Therefore you add the two angles.
Answer:
(13/2)^27
Step-by-step explanation:
First note that ( )^0 = 1, so we need not bother with the last term.
Next, note that
(2/13)^(-6) divided by (2/13)^3 is (2/13)^(-9).
Finally, we must cube this last result. We get: (2/13)^(-9*3) = (2/13^(-27)
or
(13/2)^27
Note: we're "evaluating" an algebraic expression here, not "solving it," since there is no equation here.
