Answer:
$25 a lamp
Step-by-step explanation:
First divide $10,000 by 500 lamps to find how much one of them cost
That is $20 a lamp so then multiply .25 *20 or 1/4 *20
you get 5 than add 20 +5=25
2 (x^3 - 2y^2 -5)
hope this helps
you are trying to factor as much out as possible from each
in this case, it is 2
8/11 is the answer
I use this trick: When tryig to find repeating numbers divide by 11 or 9
When dividing by 9 the numerator will be the first number in the decimal
When dividing by 11 the numerator will be one more than the first number in the decimal
4 hours and 15 minutes =4+15/60=4.25 hours
the average speed of the train = 250/4.25=58.82mph
