Answer:
I think it is 26%
Step-by-step 124 divided by 479
So 8 to the blank power divided by 8 to the negative 4 power=8 to the 9th power so
simplify
8^-4 means a reciprocal so 8^-4 means 1/(8^4) or 1/4096
8^9 is 134217728
so (8^x)/(1/4096)=134217728
multiply both sides by 1/4096
8^x=134217728/4096=32768
32768= 2^15 or 2*2*2*2*2*2*2*2*2*2*2*2*2*2*2 or since we know that 8=2*2*2 we can group the 2's this way (2*2*2)(2*2*2)(2*2*2)(2*2*2)(2*2*2) we notice that there are 5 groups so 8^5 is the answer so x=5

Answer:
x = 12.5
Step-by-step explanation:
The value of x is part of the value of an angle in a triangle where the other angles are known. This suggests that the relevant theorem is the "angle sum theorem," which tells you <em>the sum of angles in a triangle is 180°</em>.
This gives you the equation ...
60° +60° +(4x+10°) = 180° . . . . total of all angles is 180°
4x +130° = 180° . . . . . . . . . . collect terms
4x = 50° . . . . . . . . . . . . subtract 130° from both sides
x = 12.5° . . . . . . . . . divide both sides by 4
