Yes. <u>Integers are </u><em><u>whole numbers</u></em><u>.</u> Since 10 & -10 are whole numbers (they have no fractional part), this means that they are integers.
To find out how much each book cost first we will subract to find out how many 2 books cost. Then we will divide. last but not least we will check our wok. Lets do it:-
30 - 8.95 = <span>21.05
</span><span>21.05 - 7.25 = 13.80
</span>
CHECK OUR WORK:-
13.80 + 7.25 = 21.05
21.05 + 8.95 = 30
We were RIGHT!!!
Now lets divide:-
13.80 ÷ 2 = 6.90
1 book costs $6.90.
CHECK OUR WORK:-
6.90 × 2 = 13.80
We were RIGHT!!!!
So, 1 book costs $6.90.
Hope i helped ya!!
Answer:
That would be a histogram.
Step-by-step explanation:
Well it wont be a line graph because the data given is not a function. Also a bar graph shows categorical data which is different from a histogram because histogram shows numerical data. Also bar graph uses graphic presentation to compare different categories of data while a histogram shows frequencies of numerical data. Since our given data is a numerical data as well as the same kind of data we would therefore use a histogram.
The number is -240 because -240 divided by 4 is -60
