Answer: 6,520 miles per year
Step-by-step explanation:
They had driven the car for 53,790 miles in 8.25 years.
The average number of number of miles driven per year is:
= 53,790 / 8.25 years
= 6,520 miles per year
<em>They drove an average of 6,520 miles per year.</em>
Answer:
I believe the correct answer is B.
Answer:
7(1-2n)
Step-by-step explanation:
7-14n
Rewrite
7*1 - 7*2n
Factor
7(1-2n)
A proportion is a statement that two ratios are equal. A ratio is a comparison of two different quantities. "Miles per hour" is a ratio. "Dollars per pound" is a ratio. A proportion is that two of these things are equal.
For example, paying $2/pound for apples is the same as paying $6 for 3 pounds:
That's a portion.
When working with proportions in word problems, you start by setting up one ratio/fraction where you know all the information. You then set up the second one that's missing a piece of information, but you make sure to set it up using the same structure.
If your first ratio is "miles over hours," then the next ratio has to have the same organization.
If your first ratio is "rise over run," then the next ratio has to have the same organization.
Total cost independent variable
Pounds of candy dependent variable
Step-by-step explanation:
A variable is a condition that is liable to change. Most experimental hypothesis use variables to draw up suitable statements to test.
- An independent variable is that variable that does not rely on another variable. It induces the change or variation in another variable. In the statement above, the total cost is the independent variable.
- The other variable which is the effect resulting from the variation of the independent variable is the dependent variable. Here it is the number of pounds of the candy that changes when total cost varies.
