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. :)

3x+6=6+3x
Answer:
x = 9
Step-by-step explanation:
Solve for x:
x^2 - 18 x + 81 = 0
Write the left hand side as a square:
(x - 9)^2 = 0
Take the square root of both sides:
x - 9 = 0
Add 9 to both sides:
Answer: x = 9
So basically there are four sides. 51 1/8 + 51 1/8 because two sides are that length. the answer in decimal form would be 102.25. now do 38 1/4 + 38 1/4 = 76.50. the answer is 178.75 feet.
