Look it up, I tried looking it up on google for you but it said “No solution,” so I don’t really know, I’m sorry :(
3xy^z: exponent is not a nonnegative int.
r-2s: it is not a product
(ab)^1/2: exponent is not a nonnegative int.
Answer:
x = 8
Step-by-step explanation:
4x + 3 = 35
subtract 3 from both sides
4x + 3 - 3 = 35 - 4
4x = 32
divide both sides by 4
4x / 4 = x
32/4 = 8
we're left with x = 8
This is an interesting problem. You have to get the absolute value by itself. So divide by -4.
An absolute value can NEVER be a negative number.
The speed of the train in miles per hour which is the ratio of the total distance covered and the total time taken to cover the distance is 9.79 mph
- Total distance covered = 7 and 5/6 miles = 7.83333 miles
- Total time taken = 4/5 of an hour = 0.8 hour
Recall :
Speed in miles per hour = Distance covered / time taken
- The speed of the train = 7.833333 ÷ 0.8 = 9.7916
- The speed of the train in miles per hour = 9.79 mph
Therefore, the speed of the train in miles per hour as calculated from the distance covered by the train over a certain period of time is 9.79 mph
