Answer:
To simplify the given radical form, we must recall some properties of exponents as shown below. 1. 1/x⁻ⁿ = xⁿ 2. x¹/² = √x Now, going back to 1/x⁻³/⁶, we have 1/x⁻³/⁶ = x³/⁶ x³/⁶ = x¹/² x¹/² = √x Using the properties provided, we have a simplified form of √x. Answer: √x

The ratio between the number of students (s) on a field trip and the number of teachers (t) on the field trip is 21/4. There are 84 students going on the field trip. How many teachers must go? *
Answer:
Step-by-step explanation:
If there needs to be 4 teachers per 21 students, you would divide the total amount of students by 21 and multiply that answer by 4. SO...:
84 ÷ 21 = 4 groups of 21 students.
4 groups × 4 teachers = 16

Find the midpoint of a segment with the given endpoints.
W(-2,5), X(3,-17) =
Answer:
The answer is
[tex]( \frac{1}{2} \: , \: - 6)[/tex]Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
W(-2,5) and X(3,-17)
The midpoint is
[tex]M =( \frac{ - 2 + 3}{2} , \: \frac{5 - 17}{2} ) \\ = ( \frac{1}{2} \: , \: - \frac{12 }{2} )[/tex]We have the final answer as

Answer:
(x+12)
Step-by-step explanation:
x2 + 8x - 48
x2 + 12x - 4x - 48
(x-4)(x+12)
The factors of the expression are:
(x + 12) and (x - 4).
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To determine which of the options is a factor of x² + 8x - 48,
We can use either factoring or the quadratic formula.
First, let's try factoring:
x² + 8x - 48 = 0
We need to find two numbers that multiply to -48 and add to 8.
One possible pair of numbers is 12 and -4:
(x + 12)(x - 4) = 0
Now we can see that x = -12 or x = 4 are the solutions to the equation. None of the options given match these solutions.
Therefore,
The factors of the expression are:
(x + 12) and (x - 4).

Linda just turned 15 and is planning to go to college. She has researched her favorite Texas university and discovered the tuition there is around $14,000 per year. From her 15th birthday, Linda received a $5000 gift that she will use for her first year of college tuition. Linda will begin her new part time job soon and wants to save money every month for the next 3 years to also contribute to her first year of college. What is the minimum amount of money Linda needs to save in order to completely pay for her first year of college tuition?
Answer:
Linda needs to raise a minimum of $9,000 to completely pay for her tuition fee for the first year, that is, $250 per month
Step-by-step explanation:
Tuition fee = $14,000 per year
Linda received a $5000 gift that she will use for her first year of college tuition during her 15th birthday
Amount remaining = Tuition fee - gift money received
= $14,000 - $5,000
= $9,000
Linda needs to raise $9,000 in the next three years to contribute to her first year of college tuition
The minimum amount Linda needs to save each month in the next three years to raise $9,000
= Remaining tuition / 3 years
= $9,000 / 3 * 12 months
= $9,000 / 36 months
= $250 per month

Vladimir buys 1.20 pounds of Skittles, 7/2 pounds of M&Ms, and 5.2 pounds of pretzels. If the candy cost $1.20 a pound and the pretzels cost $1.10 a pound, how much did Vladimir spend?
Answer:
$11.36
Step-by-step explanation:
1.20 x 1.20= 1.44
7/2 x 1.20= 4.2
1.44 + 4.2= 5.64
5.2 x 1.10= 5.72
5.64 + 5.72= 11.36

Miki has 104 nickels and 88 dimes. She wants to divide her coins into groups where each group has the same number of nickels and the same number of dimes. What is the largest number of groups she can have?
Given :
Miki has 104 nickels and 88 dimes.
She wants to divide her coins into groups where each group has the same number of nickels and the same number of dimes.
To Find :
Largest number of groups she can have .
Solution :
In the given question we need to find the largest number of groups she can have i.e we have to find the LCM of 104 and 88 .
Now , factorizing both of them , we get :
[tex]104=1\times 2\times 2\times 2\times 13[/tex]
[tex]88=1\times 2\times 2\times 2\times 11[/tex]
Form above , we can say that common factors are :
[tex]HCF=2\times 2\times 2=8[/tex]
Therefore , the largest number of groups she can have is 8 .
Hence , this is the required solution .

The formula a = m − n represents the actual cost, a, of an item with original price m after a coupon for n dollars off is applied. Solve the formula for the amount of the coupon. Group of answer choices n=a+m n=m−a n = a − m n = −m − a
Answer: Option B.
Step-by-step explanation:
The given formula is
[tex]a=m-n[/tex]
where,
a = actual cost of an item.
m = Original price
n = Amount of coupon
We need to solve the formula for the amount of the coupon (n).
In means, we need to isolate n in the given formula.
We have,
[tex]a=m-n[/tex]
Subtract m form both sides.
[tex]a-m=m-n-m[/tex]
[tex]a-m=-n[/tex]
Multiply both sides by -1.
[tex]-(a-m)=n[/tex]
[tex]-(a)-(-m)=n[/tex]
[tex]-a+m=n[/tex]
So, [tex]n=m-a[/tex].
Therefore, the correct option is B.

What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given expression is 14x - 2. The value of x is 7. The value of the expression at x =7 will be calculated as:-
E = 14x - 2
E = 14 x 7 - 2
E = 96
Therefore, the value of the expression at x = 7 will be 96.
