420.00 that's how much he would have saved in a year
Answer:
Yes this is a proportional relationship.
Equation is;
D=20T
Step-by-step explanation:
A horse run;
800m in 40 seconds
1200m in 60 seconds
and
480m inn 24 seconds
800m ÷ 40s = 1200m ÷ 60s = 480m ÷ 24s = 20
The equation here is Distance(D) = 20 × Time(T)
D=20T
It implies that the distance of the horse is directly proportional to the time it takes to run.
Considering the given box-and-whisker plot, it is found that the bookstore sold between 2 to 12 books in 20 days.
<h3>What does a box-and-whisker plot shows?</h3>
A box and whisker plot shows three things:
- The 25th percentile, which is the median of the bottom 50%.
- The median, which splits the entire data-set into two halfs, the bottom 50% and the upper 50%.
- The 75th percentile, which is the median of the upper 50%.
From the plot given in this problem, the have that:
- The 25th percentile is of 2.
- The 75th percentile is of 12.
This means that the percentage of days in which between 2 to 12 books were sold is:
P = 75 - 25 = 50%.
Hence, out of 40 days, the amount of days is:
0.5 x 40 = 20 days.

Answer:
No Solution.
Step-by-step explanation:
-1/2x + y = 4
y = 1/2x + 6 Transposing:
- 1/2 x + y = 6
Comparing the first and third equations we see that left sides are the same and right sides are different, so there is NO Solution.
