Answer:
Step-by-step explanation:
Add 29 to both sides of this equation, obtaining: x² - 10x + 25. At this point it becomes obvious that this is a perfect square, the square of x - 5.
Thus, in the first two blanks, write x - 5.
In the second two blanks, write 5 (since 5 is the root corresponding to the factor x - 5).

The median of the data set 42, 67, 33, 79, 33, 89, 21 is 42 after arranging the data set in ascending order.
What is the median?
A median is a middle number in a series of numbers that have been arranged to lift, and it might be more informative of the set of data than the average. When there are extremes in the sequences that might affect the average of the numbers, the median is sometimes employed instead of the mean.
It is given that:
The data set is:
42, 67, 33, 79, 33, 89, 21
First, arrange the number in ascending order:
21, 33, 33, 42, 67, 79, 89
From the definitionof the middle term representing the median of the data set 42, 67, 33, 79, 33, 89, 21
The middle term = 42
The median of the data set = 42
First, you want to put all the numbers in order from least to greatest.
Thus, the median of the data set 42, 67, 33, 79, 33, 89, 21 is 42 after arranging the data set in ascending order.

Now, you can use this song to help remember how to do these problems.
Cross off the sides till you get to the center. 1 is good, 2 is bad. (If you get two numbers in the middle) add then divide by two.
Cross off 21, then 89, then 33, then 79, then 33, then 67. Now, you're left with 42 in the middle. That is your median. Hope this helps! :)

Casey
To find the number of pages Casey read today subtract the page number he started reading on to the page he stopped on.
280 - 160 = 120
Casey read 120 pages today.
Now you need to find how many pages Casey read in one hour.
If Casey read 120 pages in 2.5 hours, you can find how many pages he read in one hour by dividing 120 by 2.5.
120 ÷ 2.5 = 48.
Casey read 48 pages in one hour.
Casey was on page 160 at 5:30, and you need to find what page he was on at 3:30. Since Casey read for 2 hours before he reached page 160, you need to subtract 2 hours worth of reading from that number.
160 - (2×48)
160 - 96
64
Casey was on page 64 at 3:30 pm today.

Convert these mixed numbers into improper fractions.
-45/8 + 7/2
Find the common denominator which is 8 in this case.
-45/8 + 7(4) / 2(4)
-45/8 + 28/8
Which equals -17/8

y=C/x
C: Constant
Cross multiplication
yx=C
x=5 when y=3
Replacing in the equation above:
(3)(5)=C
when x=2 1/2=2+0.5→x=2.5, y=?
xy=C
(2.5)(y)=C
Equaling the two equations:
C=C
(2.5)(y)=(3)(5)
2.5/3=5/y
Solving for y. Dividing both sides of the equation by 2.5:
(2.5)(y)/(2.5)=(3)(5)/(2.5)
y=6
Answer:
2.5/3=5/6
