Add or subtract if possible. 10√27 - 4√12
The subtraction of the expression 10√27 - 4√12 is 22√3.
Combining things and counting them as one big group is done through addition. In math, addition is the process of adding two or more integers together.
In mathematics, subtraction involves removing anything from a group or a number of objects. What is left in the group gets smaller when you subtract.
Consider the expression,
y = 10√27 - 4√12
Now, the number in the root can also be written as:
27 = 3 × 3 × 3
12 = 2 × 2 × 3
Therefore,
y = 10√27 - 4√12
y = 10[ √(3 × 3 × 3) ] - 4[ √( 2 × 2 × 3 ) ]
y = 10 × 3√3 - 4 × 2√3
y = √3 ( 10 × 3 - 4 × 2 )
y = √3 ( 30 - 8 )
y = 22√3

We are given that:
Jocelyn received 25 reward points just for signing up.
She earns 12.5 points for each visit that she makes to the movie theatre.
The free movie ticket is available when she has 170 points with her.
Points to be collected more for a free movie ticket will be:
Points = 170 points - 25 points = 145 points.
So, the number of visits she has to make to the movie theatre will be calculated with the help of division.
Number of visits = 145 points / 12.5 points
Number of visits = 11.6 visits that is 12 visits.

Given a term in the sequence and the common ratio find the first term:
Please show work!! ASAP!! I’m desperate
============================================================
Explanation:
[tex]g_3 = 6.25[/tex] tells us that the third term is 6.25
The common ratio r = 5/4 = 1.25 tells us how to get the next term. We multiply the third term by 1.25 to get the next term
4th term = (3rd term)*(r) = (6.25)*(1.25) = 7.8125
--------------
To go backwards and find the second term, we will divide by r, which is the inverse operation of multiplication.
2nd term = (3rd term)/r = (6.25)/(1.25) = 5
Use the same idea to find the 1st term
1st term = (2nd term)/r = 5/(1.25) = 4 is the final answer

The statement [tex]log_{2} 4 + log_{2} 8 = 5[/tex] is true.
We have been given two logarithm terms that is the first term is [tex]log_{2} 4[/tex] and second term is [tex]log_{2} 8[/tex].
The properties of logarithm that we are going to use are
[tex]log a^{m} = m *log a[/tex] and [tex]log_{a} a = 1[/tex]
First we will find the value of the two terms by operating the above mentioned properties of logarithm to obtained the values of the logarithm.
Thus,
[tex]log_{2} 4 = log_{2} 2^{2} \\ = 2* log_{2} 2\\ = 2*1\\ = 2[/tex]
Similarly,
[tex]log_{2} 8 = log_{2} 2^{3} \\ = 3* log_{2} 2\\ = 3*1\\ = 3[/tex]
Now adding both the terms by substituting its respective values which we have calculated above, we get

Answer:
No
Step-by-step explanation:

Find an equation of the line passing through the point (6,-1) that is parallel to the line y = -3/2x- 3
Step-by-step explanation:
parallel means it has the same slope.
the slope is always the factor of x : -3/2
I guess the needed equation is in slope-intercept form :
y = ax + b
"a" being the slope, "b" being the y intercept (the y value when x = 0).
but since we have a point on the line and its slope, we can start with the point-slope form
y - y1 = a(x - x1)
"a"is again the slope, (x1, y1) is the given point.
and then we transform this into the slope-intercept form.
in our case we have
y - -1 = -3/2 × (x - 6)
y + 1 = -3x/2 + 18/2 = -3x/2 + 9
y = -3x/2 + 8
or
y = -3/2 x + 8
or
y = -1/2 × (3x - 16)

Divide using long division or synthetic division:
(10x^3-x^2-29x-30)/(x^2-x-2)
Answer:
10 x^3 - x^2 - 29 x - 30 = (10 x + 9)(x^2 - x - 2) + -12
Step-by-step explanation:
Compute (10 x^3 - x^2 - 29 x - 30) ÷ (x^2 - x - 2) using polynomial long division:
x^2 - x - 2 | 10 x^3 | - | x^2 | - | 29 x | - | 30
To eliminate the leading term of the numerator, 10 x^3, multiply x^2 - x - 2 by 10 x to get 10 x^3 - 10 x^2 - 20 x. Write 10 x on top of the division bracket and subtract 10 x^3 - 10 x^2 - 20 x from 10 x^3 - x^2 - 29 x - 30 to get 9 x^2 - 9 x - 30:
| | | | | 10 x | |
x^2 - x - 2 | 10 x^3 | - | x^2 | - | 29 x | - | 30
| -(10 x^3 | - | 10 x^2 | - | 20 x) | |
| | | 9 x^2 | - | 9 x | - | 30
To eliminate the leading term of the remainder of the previous step, 9 x^2, multiply x^2 - x - 2 by 9 to get 9 x^2 - 9 x - 18. Write 9 on top of the division bracket and subtract 9 x^2 - 9 x - 18 from 9 x^2 - 9 x - 30 to get -12:
| | | | | 10 x | + | 9
x^2 - x - 2 | 10 x^3 | - | x^2 | - | 29 x | - | 30
| -(10 x^3 | - | 10 x^2 | - | 20 x) | |
| | | 9 x^2 | - | 9 x | - | 30
| | | -(9 x^2 | - | 9 x | - | 18)
| | | | | | | -12
The quotient of (10 x^3 - x^2 - 29 x - 30)/(x^2 - x - 2) is the sum of the terms on top of the division bracket. The remainder is the expression that remains after the final subtraction step.
| | | | | 10 x | + | 9 | (quotient)
x^2 - x - 2 | 10 x^3 | - | x^2 | - | 29 x | - | 30 |
| -(10 x^3 | - | 10 x^2 | - | 20 x) | | |
| | | 9 x^2 | - | 9 x | - | 30 |
| | | -(9 x^2 | - | 9 x | - | 18) |
| | | | | | | -12 | (remainder) invisible comma
(10 x^3 - x^2 - 29 x - 30)/(x^2 - x - 2) = (10 x + 9) - 12/(x^2 - x - 2)
Write the result in quotient and remainder form:
Answer: 10 x^3 - x^2 - 29 x - 30 = (10 x + 9)(x^2 - x - 2) + -12

Solve each equation. Check for extraneous solutions. 3√2 x+6=18
The solution of the equation 3√2 x + 6 = 18 is 2√2.
An extraneous solution is one that results from the process of addressing the problem but is not a legitimate solution to the problem, such as the answer to an equation.
A formula known as an equation uses the equals sign (=) to express how two expressions are equal.
Consider the equation,
3√2 x + 6 = 18
Subtracting 6 from each side of the equation.
3√2 x + 6 - 6 = 18 - 6
3√2 x = 12
Dividing each side of the equation by 3.
( 3√2 x / 3 ) = ( 12/3 )
√2 x = 4
Dividing each side of the equation by √2.
( √2x/√2 ) = ( 4/√2 )
x = 2√2
Now checking the extraneous solution:
x = 2√2
[tex]3\sqrt{2}x + 6 = 18\\ 3\sqrt{2} \times 2\sqrt{2} + 6 = 18\\ 6(2) + 6 = 18\\ 18 = 18[/tex]

30in < h < 50 in.
How to write the inequality?Here we know that the allowed height of the child can be any value between 30 inches and 50 inches (not included, so we need to use the symbols > and <)
So, if we define h as the height, then h must be larger than 30 inches, so we can wrte:
h > 30 in
And h must be smaller than 50 inches, then:
h < 50 in.
If we write these two inequalities as one, we get:

An angle measures 138° less than the measure of its supplementary angle. What is the
measure of each angle?
The measure of each angle is 159° and 21°.
What are supplementary angles?When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together. The Latin word "angulus," which means "corner," is where the word "angle" originates.Two angles are considered to be supplementary if their sums total 180 degrees. For instance, angle 130° and angle 50° are complementary angles since the sum of these two angles is 180°.So, supplementary angles = 180
Then,
2x + 138 = 1802x = 180 - 1382x = 42x = 2121 + 138 = 159Therefore, the measure of each angle is 159° and 21°.

Simplify each expression. Rationalize all denominators. 1-√3 x / √6 x
After simplifying and rationalizing the expression 1 - √ 3 x / √ 6 x, we get the result as - (√ 2 / 2) + (√6 / 6) x .
We are given the expression:
1 - √ 3 x / √ 6 x
We need to simplify each expression by rationalizing the denominator.
Multiply √ 6 in both numerator and denominator, we get that:
(1 - √ 3 x) / √ 6 x × ( √ 6 / √ 6)
We get that:
= (√ 6 - 3 √ 2 x) / 6 x

How to find the slope and y-intercept of a line?The graph is a linear function.
The graph can be represented in a slope intercept form as follows;
y = mx + b
where
m = slopeb = y-interceptTherefore, using (1, -9)(-4, 6)
m = 6 - (-9) / -4 - 1
m = 6 + 9 / -5
m = 15 / -5
m = -3
Therefore,
slope = -3
Let's find the y-intercept as follows;
(1, -9)
