Step-by-step explanation:
let the number be x
So,
(x - 6) × 2 = 22
2x - 12 = 22
2x = 34
x = 17
Thus, the answer is 17
Through a given point not contained in a given line, there exists ___ ___ line parallel to the given line. (two words)
Through a given point not contained in a given line, there exists exactly one line parallel to the given line.
What are parallel lines?In Mathematics, parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and they can never meet. In Geometry, two (2) lines are parallel under the following conditions:
m₁ = m₂
Note: m represents the slope.
This ultimately implies that, two (2) lines would be parallel to each other when the slope (m₁) of the first line is equal to the slope (m₂) of the second line.
According to the Parallel postulate, there is always exactly one line that is parallel to a given line in the same plane when a point and a line are given, provided that the point is not on that line.

Answers to both the subparts using mathematical operations are shown:
(A) Rate of the car in miles/min: 0.95 miles/min
(B) Distance traveled in 5 min: 4.8 miles
What are mathematical operations?Calculating a value using operands and a math operator is referred to as performing a mathematical "operation."
The math operator's symbol has predetermined rules that must be applied to the supplied operands or numbers.
PEMDAS stands for Parentheses, Exponents, Multiplication, Division, and Addition Subtraction (from left to right).
So, we know that the rate of the car is 57 miles/hour.

Explain the term standard error?The population mean's likelihood to differ from a sample mean is indicated by the standard error of a mean, and simply standard error. It reveals how much what the sample mean will change if a study were to be repeated with fresh samples drawn from a single population.If n is the sample size and p is the genuine population proportion, then the sampling distribution of a sample proportion is thought to adhere to the normal distribution.

If two-thirds of a women’s age is 42, how old is she
Answer: 63
Step-by-step explanation:
You can put this solution on YOUR website! Hi there, 2/3 = 42. Multiply 42 by 3 = 126. Divide 126 by 2 = 63. The lady's age. 63yrs old. Proof: 2/3 x 63
Answer:
63
Step-by-step explanation:
42 / 2 = 21
21 * 3 = 63
If 42 is two thirds, then one third is 21 because (2/3) / 2 = 1/3.
If 21 is one third, then the whole is 63 because (1/3) * 3 = 1.
This year's soybean crop of 224000 t represents an increase of 40% over last year's crop. How many tons of soybeans were produced last year?
well, last year it was "x", which oddly enough is the 100%.
now, this year is 224000 tons, and that's an increase of 40%, so that's really the 100% + 40% = 140%, so if 224000 is the 140%, what's "x"?

Find the 42nd term.
Answer:
ANS:- 67
Step-by-step explanation:
d = a2 - a1
a2 = 307, a1 = 313
d = 307 -313 = -6
an = a1 + (n - 1)d
a1 = 313, n = 42, d = -6
a42 = 313 + (42 -1)(-6)
a42 = 313 + (41)(-6)
a42 = 313 - 246

What shape is a rectangle?An enclosed 2-D shape called a rectangle has four sides, four corners, and four right angles (90°). A rectangle has equal and parallel opposite sides. A rectangle has two dimensions—length and width—because it is a two-dimensional form.
What is the formula for area of rectangles?
To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle as Area = length x width
Length of the sheep pen =80 ft
bought fencing = 180 ft
One side of rectangular sheep pen is covered with barn which is equaling the width
perimeter of rectangular sheep pen = 2(length +width)

How do I solve for x?
Answer:
x = 5
Step-by-step explanation:
Since this is an isosceles triangle, the two angles opposite the congruent sides are also congruent. That means that ∠A and ∠C both equal 73°, you don't even need to solve the equation with y in it. Since all the angles in a triangle add up to 180°, we know that ∠B is equal to [tex]180-(73*2)[/tex], which is 34. So if [tex]34=6x+4[/tex], then you can solve to get [tex]x=5[/tex].

Solve x2 + 2x + 7 = 0 using the quadratic formula. Select all solutions that apply.
Solving the equation x²+2x+7 using the quadratic formula, the resultant answer is x = -1 ± 2.44949i.
What is the quadratic formula?Any quadratic problem can be solved using the quadratic formula.
The equation is first changed to have the form ax²+bx+c=0, where a, b, and c are coefficients.
After that, we enter these coefficients into the following formula:
(-b±√(b²-4ac))/(2a)
Quadratic equations can be solved using one of three main strategies: factoring, the quadratic formula, or completing the square.
So, solving x²+2x+7 using the quadratic formula as follows:
Quadratic formula: (-b±√(b²-4ac))/(2a)
Substitute values and caluclate:
x = (-b±√(b²-4ac))/(2a)
x = (-2±√(2²-4(1)(7))/(2*1)
x = (-2±√4-28)/(2)
x = (-2±√-24)/(2)
Complex roots:
x = (-2±2√6i)/(2)
x = -2/2 ± 2√6i/2
Simplifying fractions:
x = -1 ± √6i
So, we have:
x = -1 ± 2.44949i
Therefore, solving the equation x²+2x+7 using the quadratic formula, the resultant answer is x = -1 ± 2.44949i.

Which recursive sequence would produce the sequence
10,35,135,...?
Answer:
10, 35, 135, 410, 1235, ...
Step-by-step explanation:
a(1) = 10
a(n) = 3 * a(n-1) + 5
This recursive sequence starts with the initial value of a(1) = 10, and each subsequent term is calculated by applying the formula a(n) = 3 * a(n-1) + 5. The resulting sequence would be:
a(1) = 10
a(2) = 3 * a(1) + 5 = 3 * 10 + 5 = 35
a(3) = 3 * a(2) + 5 = 3 * 35 + 5 = 135
a(4) = 3 * a(3) + 5 = 3 * 135 + 5 = 410
a(5) = 3 * a(4) + 5 = 3 * 410 + 5 = 1235
And so on. This recursive sequence generates the following sequence: 10, 35, 135, 410, 1235, ...
Jesse the beetle crawls at a rate of 9 inches per minute, as modeled by the equation y=9x. His rate decreases by -8 inches per minute. Create two ordered pairs showing the distances he will crawl at 2 minutes and 7 minutes, respectively, at his new rate.

The two ordered pairs from the proportional relationship are given as follows:
2 minutes: (2,2).7 minutes: (7,7).What is a proportional relationship?A proportional relationship is defined as follows:
y = kx.
In which k is the constant of proportionality.
Initially, Jesse's rate was of 9 inches per minute, however, the rate decreased 8 inches per minute, then the constant of proportionality is obtained as follows:
