The answer is 9.63 x 10^12
7-3(4x-8)<6x+12-9x
7-12x+24<6x+12-9x
-12x-6x+9x<12-7-24
-9x<-19
-x<-19/9
x>19/9
Answer: x>19/9 or (19/9 , +∞)
Answer:
C
Step-by-step explanation:
8x-32+19=8x-13
8x-51=8x-13
16x-51=13
16x/64
X=4
Vertical angles are the same,
Set the two equations to equal each other to solve for x:
5x-7 = 8x-55
Subtract 5x from both sides:
-7 = 3x -55
Add 55 to both sides:
3x = 48
Divide both sides by 3:
x = 48 /3
x = 16
Now you have a value for x, solve angle D:
8x -55 = 8(16) - 55 = 128 - 55 = 73 degrees.
