Answer:
x=44
Step-by-step explanation:
For the two lines to be parallel, the two angles have to add to 180 degrees
45+3x+3 =180
Combine like terms
3x+48 = 180
Subtract 48 from each side
3x+48-48=180-48
3x=132
Divide each side by 3
3x/3 = 132/3
x =44
3 and a half hours i assume. so, 60 times 3 is 180, then divide by 2 to get your half, which is 30 now add that to 180. You have 210. She will travel 210 miles in 3 and a half hours. :)
Answer:
x = 14
Step-by-step explanation:
6x+x-8=6x+6
Combine like terms
7x -8 = 6x+6
Subtract 6x from each side
7x-6x-8=6x-6x+6
x-8 = 6
Add 8 to each side
x-8+8 = 6+8
x = 14
