Answer:
3/4
Step-by-step explanation:
You can simplify it by looking for what divides into both numbers. The lowest possible number is 3 because it can go into both 9 and 12.
9/3=3
12/3=4
3/4
It goes straight up I hope this helps if not in sorry
1) (2i-4)-(6i+9) = 2i-4-6i-9 = -4i-13
2) (-3+8i)+(3-8i) = -3+8i+3-8i = 0+0i = 0
Step-by-step explanation:
To solve this problem, let's set up our equation to solve for x (time to travel 13 miles).

We use this equation to find x. To solve, we divide 13 by 65 to get our answer.
13 ÷ 65 = 0.2
Our answer: 0.2 hours
