I believe it’s 77.14
Step-by-step explanation:
Answer: Divide distance by speed to get time.
Speed and time are inversely proportional. As speed increases, time decreases.
Distance = speed × time So distance is the the constant of variation.
Step-by-step explanation: Divide distance by speed to get time.
180km÷50km/h = 3.6h by Car
180km÷45km/h = 4h by Bus
180km÷40km/h = 4.5h by Truck
180km÷25km/h = 7,2h by Bicycle
Answer:
y = -8
Step-by-step explanation:
When y = -2/5, the slope is 0.
Seeing this, we can make the equation the same as the y-value of the point given.
Hence,
y = -8

Ok, I'll make it simple for you: Keep Change Change. For all subtraction problems (and only subtraction, no addition), all you have to do is keep the first number, then change the sign from a minus to a plus, and then change the last number to the opposite. For example:
7 - (-3)
7 + 3=10
-4 - 10
-4 + -10= -14
For addition, if both numbers are negative, you just add them together. For example:
-21 + (-13)= -34
In this case you switch the sign and the number's sign also:
7 + (-18)
7 - 18 = -11
I hope I was help!!!
