Answer:
$36.69
Step-by-step explanation:
Okay, so let's first write the equation:
2.59*10 + 3d = 135.97
Now, let's work on isolating d by first simplifying the equation:
25.9 + 3d = 135.97
25.9 + 3d - 25.9 = 135.97 - 25.9
3d = 110.07
3d/3 = 110.07/3
d = 36.69
Okay, now let's check:
2.59*10 + 3*36.69 = 135.97
25.9 + 110.07 = 135.97
135.97 = 135.97
Okay, so so it costs $36.69 per pair of shoe.
<h3><u>
Answer:</u></h3>
Hence, the equation of line is:
y= -6x
<h3><u>
Step-by-step explanation:</u></h3>
Clearly from the graph we could see that the line passes through the point (0,0) and (-1/2,3).
Also we know that the equation of a line passing through (a,b) and (c,d) is given as:

Here we have:
(a,b)=(0,0) and (c,d)=(-1/2,3)
Hence, the equation of line is:

Hence, the equation of line is:
y= -6x
Given:
Total number of senior students = 600
60% went on the senior trip.
One room was reserved for every 4 students.
To find:
The total number of reserved rooms.
Solution:
60% went on the senior trip from total 600 students. So, number of students who went on tripe is

Now, one room was reserved for every 4 students. So,



Therefore, the required number of reserved rooms were 90.
The answer is -6 because the square root of 36 is 6, but then you have to add the negative in front of it.
