Answer: the trip is 127 1/5 miles
Step-by-step explanation:
The distance that the martinez family drove from home to the ski lodge is 45 4/5 miles. Converting 45 4/5 miles to improper fraction, it becomes 229/5 miles.
Then, they drove an additional 17 4/5 miles to there friends house. Converting 17 4/5 miles to improper fraction, it becomes 89/5 miles
This means that the total distance that they drove while going is
229/5 + 89/5 = 318/5 miles
If the family drove the same route back home, then the distance traveled during there trip is
2 × 318/5 = 636/5 miles
Converting to mixed fraction, it becomes
127 1/5 miles
Given parameters:
Cost per pound of Arabica coffee = $28 per pound
Cost of Robusta coffee = $8.75
Given number of pounds of Robusta Coffee = 3 pounds
Total cost of blend per pound = $15.50
Unknown:
Number of pounds of Arabica coffee = ?
Solution:
Let the number of pounds of Arabica coffee = A;
We have to interpret this problem algebraically and solve;
28A + 8.75(3) = 15.5(A + 3)
Now solve the expression above for A;
28A + 26.25 = 15.5A + 46.5
28A - 15.5A = 46.5 - 26.25
12.5A = 20.25
A = 1.62
Number of pounds of Arabica Coffee is 1.62 pound
In this question, if we are trying to identify the positions of
the numbers in their respective values in the numerical form.
Then we can observe the following:
<span><span>
1. </span>The value
of 7 in 503, 497 is ones</span>
<span><span>2. </span>The value
of 7 in 26, 475 is tens</span>
<span><span>
3. </span>The value
of 3 in 6, 300 is hundreds</span>
<span><span>4. </span>The value
of 3 in 530 then is tens</span>
Understanding number positions is very vital in knowing the
digit in particularity. This benefit will be needed in cases of solving complex
and perplex equations and solutions.
