Answer:
x = 32
Step-by-step explanation:
x - 7 = 25
To solve equations, you do the some thing to both sides to isolate x.
After adding 7 to both sides we have:
x = 32
8/m-9=6/m-8
Move -9 to the other side. Sign changes from -9 to +9.
8/m-9+9=6/m-8+9
8/m=6/m+1
Move +6m to the other side. Sign changes from +6m to -6m.
8/m-6/m=6/m-6/m+1
2m could also equal to : 1/2m
1/2m=1
Multiply by 2/1 for 1/2m and 1.
1/2(2/1)m=2/1(1)
Cross out 2 and 2, divide by 2. Cross out 1 and 1, divide by 1.
m=2
Answer: m=2
your answer is x = -7+1/2
Since AED forms a straight line, all involved angles sum to 180°. Therefore AEB + BED = 180. Also, since EC bisects BED, BEC = CED, and BED = 2× CED. Now to substitute the first equation:
AEB + BED = 180
AEB + 2×CED = 180
11x-12 + 2(4x+1) = 180
11x-12+8x+2 = 180
19x-10 = 180
19x-10+10 = 180+10
19x = 190
x = 10
So what is m<AEC?? It is the sum of AEB + BEC, and since BEC = CED we can say that:
AEC = AEB + CED
AEC = 11x-12 + 4x+1 = 15x-11 = 15(10)-11 = 150-11
m<AEC = 139°
