someone pls answer my new question thanks
6/13
7/40
45/36
37/43
??? To turn them into a fraction you just make the first number the numerator and the second one denominator
His average speed for the first trip is 43 mph
Since Brian's average speed is x and he travels the first part for 215 miles in time t.
So, his distance d = xt
Also, the travels 75 more miles at a speed of 15 mph.
Since distance = speed time, the time he takes to cover this distance is
t' = distance/speed = 75 mi/15 mph = 5 hours
Since he covers both distances in the same time, we have that t = t' = 5 hours.
So, his average speed for the first trip x = d/t
= 215 mi/5 h
= 43 mph
His average speed for the first trip is 43 mph

divide gallons used by time
4 3/8 = 35/8
2 1/2 = 5/2
35/8 / 5/2 = 35/8 * 2/5 = 70/40 = 7/4 (simplest form) = 1 3/4 gallons per hour
Answer:
Step-by-step explanation:
Slope (m) =
ΔY
ΔX
=
-2
5
= -0.4
θ =
arctan( ΔY ) + 360°
ΔX
= 338.19859051365°
ΔX = 4 – -6 = 10
ΔY = -2 – 2 = -4
Distance (d) = √ΔX2 + ΔY2 = √116 = 10.770329614269
Equation of the line:
y = -0.4x – 0.4
or
y =
- 2 x
5
– 2
5
When x=0, y = -0.4
When y=0, x = -1
