Answer:
The distance is 36 miles.
Step-by-step explanation:
distance in either direction = d
total time = 5
time going = t
time returning = 5 - t
speed = distance/time
going:
speed = distance/time
18 = d/t
d = 18t Eq. 1
returning:
speed = distance/time
12 = d/(5 - t)
60 - 12t = d
d = 60 - 12t Eq. 2
Eq. 1 and Eq. 2 form a system of equations.
d = 18t
d = 60 - 12t
Since d = d, then 18t must equal 60 - 12t
18t = 60 - 12t
30t = 60
t = 2
d = 18t = 18(2) = 36
The distance is 36 miles.
F=4,which is something of an answer
Hey there!
<u><em>Supplementary angles</em></u> always equal 180° when combined. We have our ratio which is 4:2. When we combine them, we have six. This is on a different scale than 180, so we need to divide 180 by six to see how much bigger we need to make our ratio so we can find the angles.
180/6=30
As we can see, our parts of the ratio are 1/30 the size of our actual angle. To find our angles now, we multiply each number by 30.
4(30):2(30)=120:60
As you can see, if we add 120 and 60, it equals 80, and if you simplify the ratio it is still 4:2.
Your angles are 120° and 60°.
I hope this helps!
Answer:
I dont really understand it but I think it's the first one cuz that's the only one that makes sense to me hope it helped tho:))))))))
Answer:
x₍ₙ₎ = x₍₁₎ * (-5)ⁿ⁻¹
Step-by-step explanation:
x₍ₙ₎ = x₍₁₎ * (-5)ⁿ⁻¹
x₍₁₎ = -2
x₍₂₎ = (-2) x (-5)²⁻¹ = (-2) x (-5) = 10
x₍₃₎ = (-2) x (-5)³⁻¹ = (-2) x (-5)² = -50
