24 will be the answer.
Answer:
1st one twelve times the sum of a number plus twenty four
Step-by-step explanation:
12f=12xf(whatever number it is)
+
24 ^
twelve l
times
the sum of a number + 24
1) -4x-6x+8x=2-6
-2x=-4
x=-2
2)3x-4x=12-15
-1x=-3
x=3
3) 12.5x+10.25=680-410
22.75x=270
x=11.86
This is the answer .
If you need more explanation I am free
144 - 12g^2.
Because we don't know the value of g, there's nothing else we can do.
30°, 45° and 105°
2 + 3 + 7 = 12 parts
180/12 = 15 degrees each part
First angle (2 parts)
2(15) = 30°
Second angle (3 parts)
3(15) = 45°
Third angle (7 parts)
7(15) = 105°
Hope this helps
