To complete this problem, we are going to need to use the Pythagorean theorem.

1.find x. as mentioned earlier, we are going to use the Pythagorean theorum (a²+b²=c²). substitute a b and c for the values on the triangle then solve:
x²+3²=5² substitute
x²+9=25
x²=25-9 subtract
x²=14
x≈3.7 solve to the nearest tenth

2. x is about 3.7km. now we need to find y. to do so, we are going to do the same steps that we did to find x:
y²+3²=7²
y²+9=49
y²=49-9
y²=40
y≈6.3

3. now we know all 3 horizontal side lengths so all we need to do to find the total horizontal distance is add the 3 together:
3.7+3+6.3
13

4. after doing all that math we finally got the answer: The plane's total horizontal distance is about 13km.

I hope this was helpful! :)

The correct answer is A. What you do is convert feet to inches. To do this, you multiply 12 times 5 and you get 60. You subtract 60 from 63 and see that Aaron is 3 inches taller.

Answer:

-0.91

Step-by-step explanation:

Since the given question is

41x-6x=-23+9

x(41-6)=-23+9

And we are to make x the subject of formula by dividing both sides by 41-6

X=-23+9/41-6

X=-32/35

X=-0.91429~-0.91
