The difference of four times a number and seven is ten more than the number
The number is 5.67
Let the number be 'x'
The difference of four times a number and seven = 4x - 7
Ten more than the number = 10 + x
According to the condition given in the question,
The difference between four times a number and seven is equal to ten more than the number.
4x - 7 = 10 + x
4x - x = 10 + 7
3x = 17
x = 17/3 = 5.67
We can verify the answer,
Consider the LHS,
=> 4x - 7 = 4(5.67) - 7 = 22.68 - 7 = 15.68
Consider the RHS,
=> 10 + x = 5.67 + 10 = 15.67
Both LHS and RHS are equal.
Therefore the number that satisfies the given condition is 5.67

Aubrey has 64 m of fencingEli has 44 m of fencing to build a four-sided fence around a rectangular plot of land. The area of the land is 120 square meters. Solve for the dimensions (length and width) of the field. to build a four-sided fence around a rectangular plot of land. The area of the land is 255 square meters. Solve for the dimensions (length and width) of the field.
The dimensions of the rectangular field with area 120 square meters is 10 meters by 12 meters.
The measurement that expresses the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.
Given perimeter of the rectangular plot is 44 meters.
let the length is x , and width = y
Therefore perimeter = 2 (x + y)
or, 2 (x + y) = 44
or, x + y = 22
or, y = 22 - x
Now the area of the field is given as 120 square meters.
Area of the fields in terms of x is given by:
x ( 22 - x ) = 22 x - x²
Therefore 22 x - x² = 120
or, x² -22x +120 = 0
or, x² - 10x - 12x + 120 = 0
or, x (x -10) -12(x-10)=0
or, (x-10)(x-12) = 0
Now either the value of x is 10m or the value of x is 12m
Therefore the dimensions of the rectangular field is 10 meters by 12 meters.

3x^2+7-6+1+3+7 add , sub, mult, what is the answer
Answer:
If just combining like terms: 3x^2 + 12
If solving for x: 2i, -2i
Step-by-step explanation: Combine like terms, so 3x^2 + 12 = 0; move the 12 to the other side by subtracting (3x^2 = -12), then divide both sides by 3, which gives x^2 = -4. Then get the square root of both sides to cancel out the power on the x. Since -4 is negative, use imaginary numbers, which makes x = 2i and x = -2i

Four brothers have ages that are consecutive even integers. From youngest to oldest, their names are Matt, Pat, Dave, and Dan. If Dan's age is 36 years less than twice Pat's age, then what are the ages of all four brothers?
Answer:
Matt is 38, Pat is 40, Dave is 42 and Dan is 44.
Step-by-step explanation:
Let Matt's age be x.
Then Pat is x + 2, Dave is x + 4 and Dan is x + 6.
Dan's age is 36 years less than twice Pat's age:
x + 6 = 2(x + 2) - 36Solve it for x:
x + 6 = 2x + 4 - 36x + 6 = 2x - 322x - x= 6 + 32x = 38So Matt is 38, Pat is 40, Dave is 42 and Dan is 44.

Calculate the value of the sample standard deviation. Round your answer to one decimal place.
Step-by-step explanation:
first we need the mean value. this is the sum of all data points divided by the number of data points :
(3×9 + 5 - 3×13)/7 = -7/7 = -1
next, for the standard deviation, we need to sum the squares of the differences of the data points to the mean value, divide that by the number of data points again, and then pull the square root :
(3(-13 - -1)² + 3(9 - -1)² + (5 - -1)²)/7 =
= (3×196 + 3×100 + 36)/7 = (588 + 300 + 36)/7 =
= 924/7 = 132
the standard deviation is now the square root of 132 :
sqrt(132) = 11.48912529... ≈ 11.5
so, yes, as we can see, the numbers vary/deviate rather strongly from the mean value.
BD bisects AC at point E. if AE is 2x²- 8 and AC is 5x^2-25
find the length of EC
The length of EC will be 154 units.
We have the data that:
BD is the bisector of AC at point E.
This means that AE = EC
Also, AE + EC = AC
AE + AE = AC
2 AE = AC
Now,
AE = 2x² - 8 and AC is 5x² - 25
Substituting the values, we get that:
2 (2x² - 8) = 5x² - 25
4x² - 16 = 5x² - 25
5 x² - 4 x² = 25 - 16
x² = 9
x = 3 ( as length cannot be negative)
AE = EC = 2x² - 8
EC = 2 (9)² - 8
EC = 162 - 8
EC = 154 units.
Therefore, we get that, the length of EC will be 154 units.

use?
Louisa used Number
fewer dimes.
Answer:
25 quarters and 4 dimes. Louisa used 21 more quarters than she did dimes.
Step-by-step explanation:
q=number of quarters
d=number of dimes
6.65=.25q+.10d 6.65 (the total) is equivalent to the amount of quarters times .25 (the value of a quarter) plus the amount of dimes times .10 (the value of a dime)
Now divide 6.65 by .25.
26 quarters can be used.
26 times .25 = 6.50
26 quarters is $6.50
29-26=3
3 times .10 = .30
.30+6.50=6.80
This is too much. Let's try taking off one quarter.
Now we have 25 quarters. .25 times 25 = 6.25
29-25=4 (This means there will be 4 dimes if she used 25 quarters, but let's see)
4 times .10 = .40
.40 + 6.25=6.65
6.65 is the total amount she had to pay, so we did it. Solving this showed us that she used 25 quarters and 4 dimes. This equals $6.65, the amount she paid, uses only quarters and dimes, and uses a total of 29 coins.

Answer:
x° = 22°
Step-by-step explanation:
You want the measure of the angle marked x° in the figure with two parallel lines and a "bent" transversal.
Remote interior anglesExtending the upward-sloping line in the figure as shown in the attachment results in a triangle against the top horizontal line.
The angle on the right side of that triangle corresponds to the one marked 50°, so has the same measure. It is one of two "remote interior angles" whose sum is the measure of the exterior angle marked 72°. The other "remote interior angle" making up that sum is the vertical angle to the one marked x°.
So, we have ...
x° +50° = 72°
x° = 22° . . . . . . . . subtract 50°
__
Additional comment
You can do a "sanity check" on this answer by considering some extreme cases. If the 72° angle is reduced to 50°, the top leg of the "72°" angle would be horizontal. That would effectively reduce x to 0. Similarly, if the 72° angle were made to be 180°, then the value of x would be supplementary to the 50° angle. In other words, x is the difference between the one marked 72° and 50°, or 22°.

Given information:
Child admission fee = $3.00Adult admission fee = $7.00Total admissions = 297 peopleTotal admission fees collected = $1,551Define the variables:
Let x = number of children admitted to the park.Let y = number of adults admitted to the park.Create two equations from the given information and defined variables:
[tex]\textsf{Equation 1}: \quad x+y=297[/tex]
[tex]\textsf{Equation 2}: \quad 3x+7y=1551[/tex]
Solve the first equation for y:
[tex]\implies x+y=297[/tex]
[tex]\implies x+y-x=297-x[/tex]
[tex]\implies y=297-x[/tex]
Substitute the found expression for x into the second equation and solve for y:
[tex]\implies 3x+7y=1551[/tex]
[tex]\implies 3x+7(297-x)=1551[/tex]
[tex]\implies 3x+2079-7x=1551[/tex]
[tex]\implies 2079-4x=1551[/tex]
[tex]\implies 2079-1551-4x=1551-1551[/tex]
[tex]\implies 528-4x=0[/tex]

The domain of this function is all the real numbers except - 7 / 3 and 23 / 3.
What is the domain of a function?
In accordance with function theory, the domain of a function is a set of x-values such that y-values exist. Herein we find that the given function is a rational function whose denominator includes an absolute value function. The numerator is a linear equation.
Therefore, the domain of the function is all real numbers except those x-values such that denominator is equal to zero. We need to solve the following expression in two cases:
|3 · x - 15| = 8
For x ≥ 5:
3 · x - 15 = 8
3 · x = 23
x = 23 / 3
For x < 5:
- 3 · x + 15 = 8
- 3 · x = - 7
x = - 7 / 3
Then, the domain of this function is all the real numbers except - 7 / 3 and 23 / 3.

Let f(x) = [tex]3x\sqrt{2-4x}[/tex].
Find the equation of line tangent to the graph of f at x = -2.
Tangent line: y = ?
the linear equation tangent at x = -2 is:
y = 123.33*x + 226.74
How to find the equation of the tangent line?To get the slope of the line we need to evaluate the first derivative in x = -2, we get:
f'(x) = 3√(2 - 4x) + (-12/2)*3x*(2 - 4x)^(-1/2)
Evaluating in x = -2 we get:
f'(-2) = 3√(2 - 4*-2) + (-12/2)*3*-2*(2 - 4*-2)^(-1/2) = 123.33
Then the line is something like:
y = 123.33*x + b
And the line must pass through:
f(-2) = 3*(-2)*√(2 - 4*(-2)) = -18.97
So the line must pass through the point (-2, -18.97)
Replacing that in the linear equation:
-18.97 = 123.33*2 + b
-19.92 + 123.33*2 = b = 226.74
Then we conclude that the linear equation tangent at x = -2 is:
