Answer: Raymond is correct
The DJ charges $75 an hour.
=================================================
Explanation:
x = number of hours
y = total cost
The DJ does a 3-hour event for $275. This means one point is (x,y) = (3,275)
Another point is (5,425) because a 5-hour event costs $425.
Let's find the slope of the line through these two points.

The slope is 75, meaning that each time y goes up by 75, x goes up by 1.
Flipped around it means each time x goes up by 1, y goes up by 75.
This means each time we add on an extra hour, the cost goes up by $75.
The DJ charges $75 an hour. Raymond is correct.
Answer:
In 2 expression the value of x is different
Step-by-step explanation:
It is given that,
40/80 = to x/10 and x/40= 10/8
<u>To find the value of 40/80 = to x/10</u>
40/80 = x/10
x = (40*10)/80
x = 5
<u>To find the value of x/40= 10/8</u>
x/40 = 10/8
x = (40*10)/8
x = 50
From the given results we get the value of x is different.
The answer is D and it is the correct answer
B= a+4 because let’s say for the first column, b8/a4 it would be 8=4+4 which is true
