When dividing, you can flip the second fraction and multiply the two, giving you 5x/9 * 15x^2/18, which is 25x^3/54
We observe that 20 is 4 more than twice 8. This suggests the time is 1 hour and the rates are
... scooter: 20 mi/h
... bicycle: 8 mi/h
_____
You can let b represent the rate of the bicycle in miles per hour. Then we have (for time in hours and distance in miles) ...
... time = distance/speed
... time = 20/(2b+4) = 8/b
... 20b = 8(2b+4) = 16b +32
... 4b = 32
... b = 8
The rate of the bicycle is 8 mph; that of the scooter is 2*8+4 = 20 mph.
Slope is rise over run, so that would be 25/100 = 1/4
Slope is 1/4
Answer:
its 100 !!
Step-by-step explanation:
^-^
150% of 18 is 27
Divide 27 by 18:
Multiply 1.5 by 100, this will convert the decimal to a percentage:
