Find the value of x number on top is 6 and other is 9

faltersainse [42]

Answer:

x = - 12, 3

Step-by-step explanation:

By tangent secant theorem:

$x(x + 9) = {6}^{2} \\ \\ {x}^{2} + 9x = 36 \\ \\ {x}^{2} + 9x - 36 = 0 \\ \\ {x}^{2} + 12x - 3x - 36 = 0 \\ \\ x(x + 12) - 3(x + 12) = 0 \\ \\ (x + 12)(x - 3) = 0 \\ \\ x + 12 = 0, \: \: x - 3 = 0 \\ \\ x = - 12, \: \: x = 3 \\ \\$

At Brian’s Bookstore, 0.3 of the shelves hold mysteries, 25% of the shelves hold travel book and 7/20 of the shelves hold childr

elena-s [515]

Children books covers the most shelf space in the store

Solution:

From given,

Shelves that hold Mysteries = 0.3

Shelves hold travel book = 25 %

Shelves hold children’s books = $\frac{7}{20}$

To find: Type of book that covers the most shelf space in the store

You cannot compare values which are in different forms, so you need to convert.

Let us convert the given values into decimal form

Shelves hold travel book = 25 %

Percentage can be converted to decimal by dividing by 100

$\rightarrow 25\% = \frac{25}{100} = 0.25$

Shelves hold children’s books = $\frac{7}{20}$

$\rightarrow \frac{7}{20} = 0.35$

Which type of book covers the most shelf space in the store?

Now we have converted them into decimal form

Shelves that hold Mysteries = 0.3

Shelves hold travel book = 0.25

Shelves hold children’s books = 0.35

$0.35>0.3>0.25$

We can clearly see that, 0.35 is the highest decimal

Therefore, children books covers the most shelf space in the store

Simplify the expression: –9w+–6w+10w+8w

Y_Kistochka [10]

Final Answer: $3w$

Steps/Reasons/Explanation:

It is common addition and subtraction because they all have w after the number. This means they are the same variable. A plus minus (+-) would be a minus (-).

Question: Simplify the expression: $-9w +- 6w + 10w + 8w$ .

Step 1: Simplify.

$-9w - 6w + 10w + 8w$

Step 2: Simplify.

$3w$

What are the correct answers to this math sheet?

EastWind [94]

1.
a. your answer is correct
b. 60 and hndreths=60.08
c. 16 and 8 thousanths=16.008
d. 60 and 8 tenths=60.8
e. your answer is correct
f. your answer is correct

2. 16.207, 6.9, 16.19, 16.26
so the greatest is obviously one of the 16's
compare
16.207, 16.190, 16.260
obviously, the order is 16.260,16.207,16.190
then the last one is 6.9 so the order is 16.26,16.207, 16.19, 6.9 and the numbers in order is 2,4,3,1

3. I can't see the puzzle that well, but 11.88 is more than 11.50 since 0.88 is more than 0.50

4. can't see the puzzle that mmuch
hundreths is 0.0x x is the hundrreths since exg 1/100=1 hundreths=0.01

5. remember if the number is more than five round up and if less than 4 round down so
10.5, 10.6, 10.7 10.8 10.9 10.1 10.2 10.3 10.4 would work

6. tenth=0.8 so the numbers could be 17.81, 17.82 17,83

7.rembmber the decimal places and line them up so again
6.081, 6.082 6.083 and so on

8. 1/2=0.5 or 0.50000

9. the greatest decimal
first find the greatest whole number
60
then find all the 60's and read from left to right the numbers after the decimal, the biggest number to the left is bigger, if they are the same, move one place to the right and count again

10. I can't seee the puzzzle very clearly but hte answer is pirates
