Equation:
distance + distance = 2250 miles
3x + 3(x-110) = 2250
6x - 330 = 2250
6x = 2580
x = 430 mph (rate of the westbound plane)
x-110 = 320 mph (rate of the eastbound plane)

Answer:
There is one 12/4 in 3.
Step-by-step explanation:
12/4 = 3
4/4 + 4/4 + 4/4 = 12/4 = 3
Lets say you have 5 apples, but the you give away 3 of them.
To work how many you have left you take away.
5-3 = 2
Lets apply this with fractions now.
You have 9/7 yard, but then you give away 7/20 yard.
Now you take them away:
9/7 minus 7/20 = 131/140

6.7 x -2.3
You would multiply this just like any other multiplication question.
There is some work of course, but I'm not going to write it out here...
You are going to end up with -15.41, which is already rounded to the nearest hundredth.
Hope this helped :)
A.
because the total distance of every triangle 180. Add the two other angles so 42+ 57 =99. Then you have to subtract those two combined angles to find the missing one from the total distance, which is 180. 180-99=81. the answer is A. 81
