You can multiply 8 times 9 to get 72 and then move the decimal over to the right to get the answer of 7.2
The average is 13 to get the answer you add all the numbers together then divide by how many numbers you had (ex) 12+18+13+16+6=65 then you divide by how many numbers you have (ex) 65\5=13
Answer:
Step-by-step explanation:
You could multiply all of equation A by 1/6 and all of equation b by -1/4 to get
A. x-3/2y=-1/3 and B. x+1/4y=/5/4, then subtract the equations from each other to solve
1.5x+x=1380
2.5x=1380
x=552 miles
A is the solution.
