Someone might want to create a budget to treat themselves later with their saved money. Another reason it is good to have a budget is to not max out your credit card.
I think the answer is 4 more hours or 5 more
Answer:
Sum (from n = 0 to n = 33) of 10 + 15 * n
Step-by-step explanation:
The sigma notation is to express an arithmetic series as a summation, in this case we can see that it starts at 10 and ends at 505.
What we can notice is that the values are increasing by 15 units, therefore that will be the proportion that accompanies "n".
Now, we must calculate, how many times is "n", in the final value, for this we subtract the initial value, that is 10 and divide it by 15.
505 - 10 = 495/15 = 33
So "n" goes up to 33
So that series is expressed like this:
Sum (from n = 0 to n = 33) of 10 + 15 * n
Step-by-step explanation:
15=2c+7
15-7=2c
8=2c
8/2=c
4=c
c=4
Answer:
5 11/45
Step-by-step explanation:
1st, write them as improper fractions (so it is easier)
(121/9)-(41/5)
Next, make the fractions have the same denominator b finding their LCD
121/9-->605/45
41/5-->369/45
now subtract
605/45-369/45=236/45 or 5 11/45
Hope this helps ur sis
