Hi there! The answer is 102 mph.
A car travels at a steady speed and takes 5 hours to travel 510 miles.
To work out the average speed, we only need to find the speed per hour (miles per hour - mph). Since we now have our distance covered in 5 hours, we must divide by 5.
Distance covered per hour = 510 miles / 5 hours = 102 miles per hour.
Therefore the speed is 102 mph.
The altitude might be another name for a height of a pyramid, lol, hope this helps
Answer:
x = 36
Step-by-step explanation:
Subtract x and 36 from both sides.
Divide both sides by -1.
Square both sides.
Subtract 144x from both sides.
Factor the right side.
Since the solution of the equation involved squaring both sides, we musty check the answer for possible extraneous solutions.
Check x = 36:
Since 0 = 0 is a true statement, the solution x = 36 is a valid solution.
Answer:
52+p
Step-by-step explanation:
The expression says "add p to 52", so we know that we need to sum two values, one of them is the variable 'p', and the other is the value 52.
So, writing this expression in mathematical terms, we have:
52+p
With this expression, we added p to the number 52.
So the correct answer is the last one (the fifth one)
