Angle B= 180-68(int. Angle. Bc parallel to AD).
AngleB= 112 degrees
The formula of distance-time-speed
d = v × t
From the question above, we know that
⇒ The total of distance they travel is 195 miles, or it could be written as
d₁ + d₂ = 195 (equation 1)
⇒ The first person is 5 miles slower than the second person, or it could be written as
v₁ = v₂ - 5 (equation 2)
Substitute formula to equation 1
d₁ + d₂ = 195
(v₁ × t) + (v₂ × t) = 195
t(v₁ + v₂) = 195
substitute equation 2
t(v₁ + v₂) = 195
t(v₂ - 5 + v₂) = 195
t(2v₂ - 5) = 195
remember, t = 3 hours
3(2v₂ - 5) = 195
6v₂ - 15 = 195
6v₂ = 195 + 15
6v₂ = 210
v₂ = 210/6
v₂ = 35
v₁ = v₂ - 5
v₁ = 35 - 5
v₁ = 30
The rate of first person is 30 miles/hour, the rate of second person is 35 miles/hour
Answer:
64
Step-by-step explanation:
No its smaller because 15.05 can be converted to fraction form as 15 and 5 over 100 15.5 is converted as 15 and 50 over 100 or one half
so what you do is distribute the 0.9 to x and 1.4 to get 0.9x+1.26 then combine like terms 1.9x - 1.04= 1.6 then add 1.04 to both sides to get 1.9x = 2.64 divide 1.9 to both sides
answer:1.389 and if you round 1.39
