I'm not sure if this helps. but here you go.
A
120/55 will give you the time it takes him to get there. If you subtract that value from both sides, you'd have:
120/x = # hours left
From there you could easily solve his average speed home.
1) 3n+1=16-2n
- add 2n to both sides
- you should now be left with 5n+1=16
(remember the 2n gets canceled out)
- subtract 1 from both sides
- you should now be left with 5n=15
- now you divide by 5 to get n by itself
- 15 divided by 5 is 3
- n=3
2) substitute n with 3 in to the original equation
- so 3n+1=16-2n now becomes 3(5)+1=16-2(3)
- you should get 10 for both so 10=10
3) according to the segment addition postualte , XR + YR = XY.
- add 10+10 which stands for the lengths of XR and YR
Answer - XY = 20
The magnitude of the resulting vector, u - v, is approximately 5.83
and its angle of direction is approximately 59.04°.
<h3>How to find the magnitude of the resulting vector?</h3>
We want to subtract vector v from vector u.
We are given;
v = <2, -3> = 2i - 3j
u = <5, 2> = 5i + 2j
u - v = 5i + 2j - (2i - 3j)
= 5i + 2j - 2i + 3j
= 3i + 5j
Resultant vector = √(3² + 5²)
Resultant vector = √34 ≈ 5.83
Angle of direction of resultant vector is;
tan θ = (5/3)
θ = tan⁻¹(5/3)
θ = 59.04°

Answer:
54 miles.
Step-by-step explanation:
Quinn runs 3 miles 3 times every week, which means he runs 9 miles every week.
We can multiply this by 6, which we get 54, so get the amount of miles Quinn runs in 6 weeks.
