[tex] \sqrt{131} [/tex]
Answer: the second one
Step-by-step explanation:
[tex]\sqrt{131}=11.4455[/tex] and it is between 11 and 12
or we can say:

Step-by-step explanation:
Your brother has $2000 saved for vacation. His airplane ticket is $637.
Write an equality to find how much he may spend for everything else. Let x represent the amount that your brother may spend on everything else.
Answer:1367
Step-by-step explanation:Lets assume the amount spent on everything else be "x".
We know total cost can not exceed $2000.
∴ Forming an inequation to find the amount spent on everything else.
⇒
⇒
Now, solving it to find x
Subtracting both side by 637
⇒
∴
Hence, he can spend maximum of $1367 for eveything else.

Answer:
For every 5 students scoring in the 60s, there were 2 students scoring in the 70s.
Step-by-step explanation:
There are 40 scorers in the 60s and 16 scorers in the 70s. These are ratios, so the ratio between the 60s and the 70s would be 40/16. This fraction can be simplified down to 5/2. This means that for every 5 students scoring in the 60s, 2 scored in the 70s.
Substitution and Elimination Methods Nathan solves the following system of equations using the elimination method. - 2x + 3y = 6 4.3 – 6y = -12 He chooses to eliminate the variable x. Which statement correctly describes his process and solution? A: Nathan multiplies - 2x + 3y = 6 by 2 and then adds the equations. He finds the result is a contradiction, so there is no solution Nathan multiplies - 2x + 3y = 6 by 2 and then subtracts the equations. He finds the result is a contradiction, so there is no solution. B: Nathan multiplies -2.x + 3y = 6 by 2 and then adds the equations. He finds the result is an identity, so there are infinitely many solutions. C: Nathan multiplies -2x + 3y = 6 by 2 and then subtracts the equations. He finds the result is an identity, so there are many infinitely many solutions.
Answer:
Nathan multiplies −2x+3y=6 by 2 and then adds the equations. He finds the result is an identity, so there are infinitely many solutions.

What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line in point slope form can be also written as-
[tex]y-y_{1}=m\left(x-x_{1}\right)[/tex]
We have the following set of equations -
- 2x + 3y = 6
3x - 6y = -12
These are the equations of a straight line. Plotting the graphs and finding the point of intersection would give us the solution. It can be seen from the graph that the solution is given by coordinate - (0,2)
AlternativelySolving by elimination method -
- 2x + 3y = 6 ..[1]
3x - 6y = -12 ..[2]
Multiply [1] by 3 and [2] by 2 -
- 6x + 9y = 18
6x - 12y = - 24
Adding both -
- 6x + 9y + 6x - 12y = 18 - 24
-3y = - 6
y = 2
AND
- 2x + 3y = 6
-2x + 6 = 6
x = 0
Therefore, the solution for the system of equations -
- 2x + 3y = 6
3x - 6y = -12
is (0, 2)

You want to start your own business so you borrow $50,000 from the bank to pursue your dreams. You borrow it for 5 years at 3.2% simple interest rate. What is the interest INTEREST owed?
Answer:
$8000
Step-by-step explanation:
[tex]I=PRT[/tex] (I = interest, p = principal, r = interest rate, t = time. This only applies to simple interest)
[tex]I=\$50000\times3.2\%\times5[/tex] (assuming that it is [tex]3.2\%[/tex] p.a)
[tex]I=\$8000[/tex]

Seven less than 4 times the square of a number is 18. Find the two numbers.
The two numbers of seven less than 4 times the square of a number is 18 are -5/2 and 5/2
Let the unknown number be "x"
The square of an unknown number is expressed as x²4 times the square of a number is 4x²Seven less than 4 times the square of a number is 4x² - 7If the resulting expression is 18, this will be expressed as 4x² - 7 = 18
Solving the resulting expression
[tex]4x^2-7=18\\4x^2= 18+7\\4x^2=25\\x^2=\frac{25}{4}\\x=\pm \frac{5}{2}[/tex]
Hence the two numbers of seven less than 4 times the square of a number is 18 are -5/2 and 5/2

The original price of a pair of shoes is $42. The sale price is 20% off the original price. What is the amount off the original price? What is the new price for the pair of shoes? (Hint two answers!)
Answer:
a) What is the amount off the original price?
= $8.4
b) What is the new price for the pair of shoes?
= $33.6
Step-by-step explanation:
a) What is the amount off the original price?
We are told that:
The sale price is 20% off the original price.
Original price = $42
Hence:
$42 × 20%
$42 × 20/100
= $8.4
b) What is the new price for the pair of shoes?
The new price =
0riginal price - Amount off the original price
= $42 - $8.4
= $33.6
The original price = $33.6
