Morgan's way to solve the equation |2x-7| =5 is first to write |x-3.5|=2.5. explain this approach, and then finish the job.
Answer:
Morgan divided 2 throughout the original equation, giving her |x-3.5|=2.5.
x = 6 and x = 1
Step-by-step explanation:
|2x-7|=5 -- divide by 2
|x-3.5|=2.5 and |x-3.5|=-2.5 -- since this is an absolute value equation, we have to consider both positive and negative
x-3.5 = 2.5
x = 6
x-3.5 = -2.5
x = 1

James worked for 20 hours.
what is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given here, James earns $12 per hour and weekly bonus of $36 if he makes a total of 7 or more sales during a given week and earned a total of $300 . Let the time that James worked for be x , then we can form an equation;
36 + 12x = 300
⇒ 12x = 240
⇒ x = 20 hours

What’s the zero of the function on the graph PLEASE
Answer:
B) x = -5
Step-by-step explanation:
The zero of a graph is the inputted value in which the output is 0. Therefore, we must find the x-value that makes the y-value be 0. In the graph, we see that y = 0 at (-5, 0). The x-value of the coordinate (-5, 0) is -5. Therefore, the zero of the function in the graph is x = -5.

JK has endpoints located at J(15,-13) and K(-9,27) what are the coordinates of the midpoint JK.
A.(3,7)
B.(12,20)
C.(1,9)
D.(14,18)
Answer:
(3, 7)
Step-by-step explanation:
The formula for calculating the midpoint of two coordinates is expressed as:
M(X, Y) = [x1+x2/2, y1+y2/2]
Given the coordinates J(15,-13) and K(-9,27), the coordinates of the midpoints is expressed as:
X = 15-9/2
X = 6/2
X = 3
Similarly,
Y = y1+y2/2
Y = -13 +27/2
Y = 14/2
Y = 7
Hence the coordinate of the midpoint is at (3, 7)

Samuel orders four DVDs from an online music store. Each DVD costs $9.91. He has a 25% discount code,
and sales tax is 6.75%. Round sales tax amounts to the nearest cent. What is the total cost of his order?
The total cost of Samuel's order is sl
Answer:
The total cost is $32.40
Step-by-step explanation:
9.91 x 4 = 39.64
25% of 39.64 is 9.91
39.64 - 9.91 = 29.73
6.75% of 39.64 is 2.67
29.73 + 2.67 = 32.40

63 yd
х
A
(10
Answer:
65 yd
Step-by-step explanation:
The image of this walking path of Cristal is missing, so i have attached it.
From the image attached, we can see that the path "x" is the hypotenuse path a the triangle.
Thus, we can use pythagoras theorem to find the area. Thus;
x² = 16² + 63²
x = √(16² + 63²)
x = √4225
x = 65 yd
