If the equation is 0=0.64z-z+0.36z and the answer is true for all z what are 2 values to check the solution
Example of what I mean...
Answer:
You can choose trivial values such as [tex]z=0[/tex], but also something like [tex]z=69[/tex] if you feel more daring. Both equations will come out to yield [tex]0=0[/tex], which is obviously true.
Step-by-step explanation:
Because the answer is true for all [tex]z[/tex], any two values can be chosen. It is most often useful to choose easy values of [tex]z[/tex] for these kinds of situations, though.

Last year Ron bought 40 pen sets and sold 25. This year he bought 75 pen sets and sold 60. The absolute error each year was the same. Are the percent errors also the same? Explain using the solutions.
Answer:200
Step-by-step explanation:
Answer:
No, differentStep-by-step explanation:
Last yearBought 40 sets
Sold 25 sets
Error = 25 - 40 = -15Absolute error = | - 15| = 15Percent error = 15/40*100% = 37.5%This yearBought 75 sets
Sold 60 sets
Error = 60 - 75 = -15Absolute error = |-15| = 15Percent error = 15/75*100% = 20%We can see absolute errors are same but percent errors are different.
The reason is the referenced numbers are different.

Taylor had $60 dollars to buy a new pair of sneakers. He saw a pair he really liked that originally cost $72 but were on sale for 15% off. Does Taylor have enough money to buy them on sale?
Answer:
No.
Step-by-step explanation:
72 times 0.15=10.8
72-10.8=61.2
No. Taylor doesn't have enough.
You could also have done 72 times 0.85, and then you wouldn't have had to minus 10.8 and all those stuff.
Hope this helps!

Given a scale drawing of the square with a horizontal scale factor of 40% and a vertical scale factor of 240%, what are the dimensions, in units, of the scale drawing?
Your answer should fit the following format:
The length of the shorter side is _________ units, and the length of the longer side is _______ units.
Answer: The shorter side is 2 units, and the longer side is 12 units.
Step-by-step explanation: The original square is 5 units. multiply by decimal equivalents to find the new scaled units
40% of 5 is 2 That is: 0.4 × 5 = 2.0
240% of 5 is 12 That is 2.4 × 5 = 12.0
240
