Answer: 2
Step-by-step explanation:
What does x equal with this equation
x/6-33= -27
Answer:
The first thing that we have to do is add 33 to both sides to try to reduce the amount of variables on the left hand side.
[tex]\frac{x}{6} - 33 = -27[/tex]
[tex]\frac{x}{6} - 33 + 33 = -27 + 33[/tex]
[tex]\frac{x}{6} = 6[/tex]
Now that we have simplified the left hand side even more we only have one part left to get x by itself which is to multiply both sides by 6.
[tex]\frac{x}{6} = 6[/tex]
[tex]\frac{x}{6} * 6 = 6 * 6[/tex]
[tex]x = 36[/tex]
Therefore, our final answer for what the value of x equals is 36.

Rationalizing the denominator of the expression, it is found that the simplified expression is given by:
[tex]\frac{\sqrt{6}(12x + 20x^2) + 3\sqrt{x} + 5\sqrt{x^3}}{x(96x - x)}[/tex]
What is the expression that we have to simplify?It is given by:
[tex]\frac{3 + 5\sqrt{x^2}}{4\sqrt{6x^2} - \sqrt{x}}[/tex]
We rationalize the denominator, using the subtraction of perfect squares, hence:
[tex]\frac{3 + 5\sqrt{x^2}}{4\sqrt{6x^2} - \sqrt{x}} \times \frac{4\sqrt{6x^2} + \sqrt{x}}{4\sqrt{6x^2} + \sqrt{x}}[/tex]
Then, solving the expression:
[tex]\frac{(3 + 5\sqrt{x^2})(4\sqrt{6x^2} + \sqrt{x})}{16(6x^2) - x}[/tex]
[tex]\frac{12\sqrt{6x^2} + 3\sqrt{x} + 20x^2\sqrt{6} + 5\sqrt{x^3}}{96x^2 - x}[/tex]

Determine the equation of the elastic curve for the beam using the x1 coordinate for 0 ≤ x1 ≤ l/2
The elastic curve between 0 to L/2 is a cubic curve. And the elastic curve is shown in the given diagram.
What is an elastic curve?The flexible curve of a beam is the curve generated by the crossover of the horizontal member with the beam's side, with continuous stresses on the fibers considered to be within the elastic limit.
The slope at L/2 will be
[tex]\rm \theta _{L/2} = \dfrac{PL^2}{8EI}[/tex]
The deflection of the beam at L/2 will be
[tex]\rm y_{L/2} = \dfrac{P(L/2)^3}{3EI}\\\\\rm y_{L/2} = \dfrac{PL^3}{24EI}[/tex]
And the deflection of the beam at L will be
[tex]\rm y_{L} = \dfrac{PL^3}{24EI} + \dfrac{L}{2} \times \theta _{L/2} \\\\\rm y_{L} = \dfrac{PL^3}{24EI} + \dfrac{L}{2} \times \dfrac{PL^2}{8EI}\\\\\rm y_{L} = \dfrac{5PL^3}{48EI}[/tex]

Answer:
a₆ = 96
Step-by-step explanation:
assuming you mean find a₆
using the recursive rule and a₁ = 3 , then
a₂ 2a₁ = 2 × 3 = 6
a₃ = 2a₂ = 2 × 6 = 12
a₄ = 2a₃ = 2 × 12 = 24
a₅ = 2a₄ = 2 × 24 = 48

We know that midpoint of a line divides the line into two equal parts
Therefore on equating we get
[tex]4x + 1 = 8x - 15[/tex]
[tex]1 + 15 = 8x - 4x[/tex]
[tex]16 = 4x[/tex]
[tex]x = 4[/tex]
Steps:
[tex]4x+1= 8x-15[/tex]
=>subtract 4 on both sides with 8x
[tex]1=4x-15[/tex]
=>now do add 15 both sides
[tex]16=4x[/tex]
=>Now divide 4x both sides
[tex]\frac{16}{4} =\frac{4x}{4}[/tex]

Completely factor the given polynomial: 2x^2 - 8x - 10
Answer:
2(x - 5)(x + 1)
Step-by-step explanation:
2x² - 8x - 10 ← factor out 2 from each term
= 2(x² - 4x - 5) ← factor the quadratic
consider the factors of the constant term (- 5) which sum to give the coefficient of the x- term (- 4)
the factors are - 5 and + 1 , since
- 5 × 1 = - 5 and - 5 + 1 = - 4 , then
x² - 4x - 5 = (x - 5)(x + 1)
then
2x² - 8x - 10 = 2(x - 5)(x + 1) ← in factored form

Given C is the midpoint of line AB, D is the midpoint of line AC, and E is the midpoint of line DC. If AE=16, what is DB?
Answer:
DB = 32
Step-by-step explanation:
Given :
⇒ C is the midpoint of the line AB
⇒ E is the midpoint of the line DC
⇒ AE = 16
=============================================================
Understanding :
⇒ AC = BC = 1/2AB
⇒ AD = DC = 1/2AC = 1/4AB
⇒ DE = 1/2AD = 1/4AC = 1/8AB
=============================================================
Finding AB :
⇒ AE = AD + DE
⇒ 16 = 1/4AB + 1/8AB
⇒ 3/8AB = 16
⇒ AB = 16 x 8 / 3
⇒ AB = 128/3
=============================================================
Finding DB :
⇒ DB = DC + CB
⇒ DB = 1/4AB + 1/2AB
⇒ DB = 3/4AB
⇒ DB = 3/4 × 128/3
⇒ DB = 128/4
⇒ DB = 32

Can someone help me PLEASE
Let's solve this problem step-by-step:
[tex]7 * 9 = (7*10)-(7*x)[/tex]
x: it is the delta in the equation given in your pictureWe know (7*10) - (7*x) is equivalent to the 7*(10-x)
⇒ based on the Distributive Properties
[tex]a*(b+c) = ab + ac[/tex]
[tex]7*(10+(-x))=(7*10)+(7*(-x)=(7*10)-(7*x)[/tex]
So:
[tex]7*9=7(10-x)\\9=10-x\\x=10-9\\x= 1[/tex]
Thus delta (the little triangle in this problem) in this case is 1

A circle has an area of 20cm. What is its diameter?
Answer:
should be 5.05
Step-by-step explanation:
rounded to nearest hundredth
Answer:
5.02
Step-by-step explanation:
Formula for area= π x r^2
(π is 3.14)
Formula for diameter= 2 x r
So all you basically have to do is go backwords with the first equation
20/π=6.36
Now you have 6.36, though you need to go even further back because of the ^2
√6.36=2.51
Now we have the radius, so stick that into the diameter formula
2 x 2.51
5.02 is the diameter :)

Solve for the value of x :-
5(x+4)+5(2-x)
Answer:
[tex]30[/tex]
Step-by-step explanation:
Given expression:
[tex]5(x + 4) + 5(2 - x)[/tex]
Note: The value of "x" is undefined because the given sum is not an equation. Thus, I will simplify the expression as much as possible.
Let us simplify all the distributive properties stated in the expression.
Apply the distributive property rule [a(b + c) = ab + ac]
[tex]\implies5(x) + 5(4) + 5(2) - 5(x)[/tex]
Since 5(x) is being subtracted from 5(x), we get:
[tex]\implies 5(x) + 5(4) + 5(2) - 5(x)[/tex]
[tex]\implies 5(4) + 5(2)[/tex]
Finally, let us simplify the sum of the product of (5 and 4) and (5 and 2).
[tex]\implies20 + 10[/tex]
[tex]\implies \boxed{30}[/tex]
