Answer:
Step-by-step explanation:
This problem is similar to many others in which the sum of two quantities and their difference are given. The solution can be found easily when the equations for the relations are written in standard form.
<h3>Setup</h3>
Let s and h represent numbers of sodas and hot dogs sold, respectively. The given relations are ...
- s +h = 235 . . . . . combined total
- s -h = 59 . . . . . . difference in the quantities
<h3>Solution</h3>
Adding the two equations eliminates one variable.
(s +h) +(s -h) = (235) +(59)
2s = 294 . . . . simplify
s = 147 . . . . . .divide by 2
h = 147 -59 = 88 . . . . h is 59 less
147 sodas and 88 hot dogs were sold.

<em>Additional comment</em>
The solution to a "sum and difference" problem is always the same. One of the numbers is half the sum of those given, and the other is half their difference. ((235-59)/2 = 88)
A line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints. ... When the end points both lie on a curve such as a circle.

Step-by-step explanation:
First u divide 189 by 7
Than u minus that by 2 and u got ur answer
Answer: 9,953
Step-by-step explanation:
The first step is to find what the sales tax rate is for the first car because it will be the same for the second.
11,900/767 = .064
Now to find the cost of the second car we divide.
637/.064 = 9,953.125 Round to nearest dollar.
Answer:
The answer is 2.
Step-by-step explanation:
1- Suppose we have following array of ten integers: 5 3 8 9 1 7 0 2 6 4.
2- Before the last merge, the left half and the right half must be sorted. So it should be
1 3 5 8 9 0 2 4 6 7
Therefore the solution is 2.
