Answer:
The bus will take 81 minutes to complete the trip.
Step-by-step explanation:
To determine how many minutes will the bus take to complete the trip if a bus completes half a trip at 40 km per hour and the other half at 50 km per hour, and the whole trip was 60 km, the following calculation must be performed:
60/2 = 30
30/40 = 3/4 of an hour = 45 minutes
30/50 = 3/5 of an hour = 36 minutes
45 + 36 = 81
Therefore, the bus will take 81 minutes to complete the trip.
Answer:
x=
Step-by-step explanation:
1) since we are solving for x we want x to be the ONLY thing on the other side of the equation symbol:
for ex. x=
2) to do this, we need to eliminate -2, we eliminate -2 by adding 2 on both sides:
y+2=3x-2+2
y+2=3x
remove 3 by dividing it on both sides(opposite operation)
=x
this is our final equation since we have solved for x
hope this helps
Y = -1/2x + 3
Why?
Looking at the line start where the line intercepts the y line, it goes down one over 2 and that’s your slope, the 3 is bc that’s where the line crosses the y line
Answer: cos (4/5)
Step-by-step explanation:
Cosine is Adjacent over Hypotenuse
Which 8/10, then simplified to 4/5 by dividing by 2
Hope it helps!
