Answer: A) x=6
Step-by-step explanation: my trick that i do with these questions are to just fill in the x's with the different choices that they give you.
so... first try out 6. fill in every x with a 6. so now, x isn't x anymore, it's 6.
(8-6)=2
9 times 2= 18
3 times 6= 18
this means that x would equal 6
if that first one doesn't work, try out the other ones. but this one works, so we know we have the right answer. i hope this helps with this problem, and i hope it helps with other problems like this too.

Which of the following sets of numbers does square root of 49?
Answers
Answer:
7
Step-by-step explanation:
Natural numbers , Real numbers ,Whole numbers ,Integers , Rational numbers
sqrt(49) = 7
So this number is in the set of...
Natural numbersWhole numbersIntegersRational numbersReal numbersThe set of natural numbers is {1,2,3,...} and the set of whole numbers is {0,1,2,3,...}. Basically we just added in 0. Integers will be similar but we now have negative values too {..., -3, -2, -1, 0, 1, 2, 3, ...}
Rational numbers are anything of the form a/b with a,b being integers. In other words, if we can write the number as a fraction of two integers, then we have a rational number. In the case of 7, we have 7 = 7/1, so it is rational.
The set of real numbers includes every number type you have learned of so far (natural, whole, integer, etc). If you haven't learned about imaginary or complex numbers yet, then every number your teacher will go over is a real number.
Perform the row operation 1/3R1 and replace R1 on the following matrix
[3 0 0|21]
[0 6 0|5]
[0 0 7|5]
Answers
Answer:
[tex]\left[\left.\begin{matrix}1 & 0 & 0\\ 0 & 6 & 0\\ 0 & 0 & 7\end{matrix}\right|\begin{matrix}7\\ 5\\ 5\end{matrix}\right][/tex]
Step-by-step explanation:
The given augmented matrix is
[tex]\left[\left.\begin{matrix}3 & 0 & 0\\ 0 & 6 & 0\\ 0 & 0 & 7\end{matrix}\right|\begin{matrix}21\\ 5\\ 5\end{matrix}\right][/tex]
Here, we need to perform the row operation [tex]\dfrac{1}{3}R_1[/tex] and replace [tex]R_1[/tex] in the above matrix.
So, divide each element of [tex]R_1[/tex] in the given matrix and other elements remain same.
[tex]\left[\left.\begin{matrix}\dfrac{3}{3} & \dfrac{0}{3} & \dfrac{0}{3}\\ 0 & 6 & 0\\ 0 & 0 & 7\end{matrix}\right|\begin{matrix}\dfrac{21}{3}\\ 5\\ 5\end{matrix}\right][/tex]
[tex]\left[\left.\begin{matrix}1 & 0 & 0\\ 0 & 6 & 0\\ 0 & 0 & 7\end{matrix}\right|\begin{matrix}7\\ 5\\ 5\end{matrix}\right][/tex]
Therefore, the required matrix is [tex]\left[\left.\begin{matrix}1 & 0 & 0\\ 0 & 6 & 0\\ 0 & 0 & 7\end{matrix}\right|\begin{matrix}7\\ 5\\ 5\end{matrix}\right][/tex].

13. In a park there are 1596 trees in 42 rows. If each row has the same number of trees, estimate the number of trees in one row, rounded off to the nearest tens.
Answers
Answer:
The ultimate answer according to the question is is 40 trees in one row.
Step-by-step explanation:
Let no. of trees in one row be X.
There are 42 rows,
or, 42X= 1596
or, X= 1596/42
So, X=38
Now, while rounding off to the nearest ten 38 goes to 40.

Step-by-step explanation:
A rational number is an integer divided by an integer where the result is a terminating or repeating decimal.

You purchase 10,000 shares of a stock for $0.85 a share. One year later it is worth $0.95 a share. Find the profit if you sold at $0.95.
Answers
Answer:
Each share gained $0.10, which is an 11.76% increase (10/85).
The profit if the share is sold at $0.95/share, is $1000 and this can be determined by using the arithmetic operations.
Given :
You purchase 10,000 shares of a stock for $0.85 a share. After one year it is worth $0.95 a share.The following steps can be used in order to determine the profit if the share is sold at $0.95/share:
Step 1 - The arithmetic operations can be used in order to determine the profit if the share is sold at $0.95/share.
Step 2 - According to the given data, the cost of 10000 shares of a stock is $0.85 a share. So, let the total cost of 10000 shares be 'x'. So, the value of 'x' is:
[tex]x = 10000\times 0.85\\x = \$8500[/tex]
Step 3 - Now, after one year the shares price is $0.95 a share. So, let the cost of 10000 shares after one year be 'y'. So, the value of 'y' is:
[tex]y = 10000\times 0.95\\y = \$9500[/tex]
Step 4 - So, the profit if the share is sold at $0.95/share, is:
[tex]P = y-x[/tex]
[tex]P= 9500-8500[/tex]
[tex]P= \$1000[/tex]
Therefore, the profit if the share is sold at $0.95/share, is $1000.

A total of 716 tickets were sold for the school play. They were either adult tickets or student tickets. There were 66 more student tickets sold than adult tickets. How many adult tickets were sold?
Answers
Answer:
325
Step-by-step explanation:
Let the number of adult tickets sold be x
Therefore, number of students tickets sold = x + 66
Since,
Number of adult tickets + number of student tickets = 716
Therefore,
x + x + 66 = 716
2x + 66 = 716
2x = 716 - 66
2x = 650
x = 650/2
x = 325
Hence, 325 adult tickets were sold.
