the answer is B your welcome
X=2.5
Explanation:
So you would expand the parentheses on the left
4(x)+4(7)38
Which equals
4x+28=38
Then subtract 28 from both sides
4x=38-28
4x=10
Then divide by 4 10/4=2.5
X=2.5
10 liters to gallons is 2.6 gallons.
The answer will be 57 after you add 43 to both sides.
Answer: Create intervals, then count the number of countries that fall in each interval.
When you create a frequency table, you have set intervals. In this case, our small number is close to 0 and our largest number is 4.5. We could create an interval for each number. Then, count the number of countries in each.
It would look like:
Interval Frequency
0-0.99 1
1-1.99 5
2-2.99 5
3-3.99 2
4-4.99 1
