Answer:
x = 8
x = 21/14
x = 8
x = 15/21
x = 1/4
x = 7
Step-by-step explanation:
(For all instances of number, let it be x)
Double the sum of a number and 15. The result is the same as the product of 23 and the number.
2x + 15 = 23 + x
2x - x + 15 = 23 + x - x
x + 15 = 23
x + 15 - 15 = 23 - 15
x = 8
Multiply a number by 15 and add 2. The result is the same as the sum of 23 and the number.
15x + 2 = 23 + x
14x + 2 = 23
14x = 21
x = 21/14
Double a number and add 15. The result is the same as the sum of 23 and the number.
2x + 15 = 23 + x
x + 15 = 23
x = 8
Double a number and add 15. The result is the same as the product of 23 and the number. (This time we will move the x to the other side as the right side has a larger x than the left side)
2x + 15 = 23x
15 = 21x
x = 15/21
Multiply a number by 15 and add 2. The result is the same as the product of 23 and the number.
15x + 2 = 23x
2 = 8x
2/8 = x
x = 1/4
Double the sum of a number and 15. The result is the same as the sum of 23 and the number.
2(x + 15) = 23 + x
2x + 30 = 23 + x
x + 30 = 23
x = 7

A fish market bought two swordfish at a rate of $12 per pound. The cost of the larger fish was 3 times as great as the cost of the smaller fish. The total cost of the two fish was $3,792.How much did each fish weigh?The smaller fish weighed pounds.The larger fish weighed pounds.
Answer:
Large Fish: 237 lbs Small Fish:79 lbs
Step-by-step explanation:
3792 divided by 12 for the weight, is 316 divide that by 4 to get the smaller fish's weight 79 pounds. multiply that by 3 to get the larger fish's weight 237 pounds.

(3x3 + 4x2 – 2+ 7) + (x + 2)
Divident = Divisior x Quotient + Remainder
(3x³ + 4x² - 2 + 7) = (x + 2) x (3x² - 2x) + (4x - 5)
(3x³ + 4x² - 2 + 7) = (3x³ + 4x² - 2 + 7)
What is division?A division is a process of splitting a specific amount into equal parts.
We have,
(3x³ + 4x² - 2 + 7) ÷ (x + 2)
We will divide using the long division method.
Divident = Divisior x Quotient + Remainder
Divident = (3x³ + 4x² - 2 + 7)
Divisor = x + 2
We will find the quotient and the remainder.
x + 2 ) 3x³ + 4x² - 2 + 7 ( 3x² - 2x
3x³ + 6x² [ sign is changed, 3x³ = -3x³ and 6x² = -6x²]
- 2x² - 5
- 2x² - 4x [ sign is changed, -2x² = 2x² and -4x = 4x ]
4x - 5
Quotient = 3x² - 2x
Remainder = 4x - 5
Thus,
Divident = Divisior x Quotient + Remainder
(3x³ + 4x² - 2 + 7) = (x + 2) x (3x² - 2x) + (4x - 5)
(3x³ + 4x² - 2 + 7) = (3x³ + 4x² - 2 + 7)

what is the answer to 56,763 rounding to the nearest thousand
Answer:
60000
Step-by-step explanation:
56763 so you're going to take that number and you're going to run it to the nearest thousands by doing that you're going to take the six and six is either closest to zero or 10 and it is closer to 10 which would be your answer so you're going to add these zero replacing the six seven six and three in the equation and making me five of six by adding the one from the number 10 if you have any other questions text me if that doesn't make sense

[tex]\\ \sf\longmapsto cos\Theta=\dfrac{12}{24}[/tex]
[tex]\\ \sf\longmapsto cos\Theta=\dfrac{1}{2}[/tex]
Option C
The value of the cosine for the given triangle XZW will be ( 12 / 24 ). the correct option is C.
What are trigonometric functions?The trigonometric functions in mathematics are real functions that connect the right-angled triangle's angle to the ratios of its two side lengths. They are extensively utilized in various geosciences, including navigation, and solid mechanics.
Trigonometry is the branch of mathematics that set up a relationship between the sides and angle of the right-angle triangles.
The cosine ratio will be calculated by first calculating the perpendicular WZ.
WZ = 12 x tan60
WZ = 12 x √3
WZ = 12√3
Then calculate the hypotenuse of the triangle.
XZ² = 20.78² + 12²
XZ² = 430+ 144
XZ² = 574
XZ = 24
The cosine ratio will be calculated as:-
cosФ = Base / hypotenuse = 12 / 24.
Therefore, the value of the cosine for the given triangle XZW will be ( 12 / 24 ). the correct option is C.

Answer:
? =64.62306
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adjacent side / hypotenuse
cos ? = 3/7
Taking the inverse cos of each side
cos ^-1 ( cos ? ) = cos ^-1 (3/7)
? =64.62306
Answer:
The angle is approximately 23°
Step-by-step explanation:
let the angle be ∆
using trigonometrical identity,
tan ∆=3/7
tan∆=0.4286
∆=tan^-1(0.4286)
∆=23.19°

Answer:
x=-2
Step by step explanation:
Step by step explanation:Subtract 2 from both sides:
6x + 2 - 2 = - 10 - 2
Simplify
6x = - 10 - 2
Simplify the arithmetic:
6x = - 12
Then Isolate x:
6x = - 12
Divide both sides by 6:
(6x)/6 = - 12/6
Simplify the fraction:
x = - 12/6
Find the greatest common factor of the numerator and denominator:
x = (- 2 × 6)/(1 ×6)
Factor out and cancel the greatest common factor:

An input-output machine generates the information below
a- Find the values to fill in the table for variables a and b
b- write up a rule that describes the relationship between the input output.
c- what is the value of the output and input in 20?
d- what is the value of the input when the output is 77.
Using a linear function, we have that:
a) The values are: a = 11 and b = 5.
b) The rule is:
[tex]y = 3x + 2[/tex]
c) The value of the output is 62.
d) The value of the input is 25.
The equation of a linear function is given by:
[tex]y = mx + b[/tex]
In which
m is the slope, which is the rate of change.b is the y-intercept, which is the initial value.First, we are going to solve item b to find the rule, then we solve other items.
Item b:
In the table, we have two points: (1,5) and (2,8).
The slope is given by change in y divided by change in x, thus:
[tex]m = \frac{8 - 5}{2 - 1} = 3[/tex]
Then
[tex]y = 3x + b[/tex]
Point (1,5) means that when [tex]x = 1, y = 5[/tex], and this is used to find b.
[tex]5 = 3(1) + b[/tex]
[tex]b = 2[/tex]
Thus, the rule is:
[tex]y = 3x + 2[/tex]
Item a:
a is the value of y when x = 3, thus:
[tex]y = a = 3(3) + 2 = 11[/tex]
Thus, a = 11.
b is the value of x when y = 17, thus:
[tex]3b + 2 = 17[/tex]
[tex]3b = 15[/tex]
[tex]b = 5[/tex]
The values are: a = 11 and b = 5.
Item c:
The value of the output is y when x = 20, thus:
[tex]y = 3(20) + 2 = 60 + 2 = 62[/tex]
Thus, the value of the output is 62.
Item d:
The value of the input is x when y = 77, thus:
[tex]3x + 2 = 77[/tex]
[tex]3x = 75[/tex]
[tex]x = \frac{75}{3}[/tex]
[tex]x = 25[/tex]
The value of the input is 25.

What are irrational numbers?An irrational number is a number that cannot be expressed as a fraction {p/q} for any integers {p} and {q}.
Given are irrational numbers between 15 and 17.
Now, we can write -
A = 15² = 15 x 15 = 225
{A} = 225
B = 17² = 17 x 17 = 289
{B} = 289
The irrational numbers between 15 and 17 can be written as the square root of numbers between 225 and 289. So, we can write -
[tex]$\sqrt{231.44}\\[/tex]
[tex]$\sqrt{244.57}\\[/tex]
[tex]$\sqrt{277.67}\\[/tex]

A plane travels at a constant speed. It takes 6 hours to travel 3,360 miles.
a. What is the plane’s speed in miles per hour?
mph
b. At this rate, how many miles can it travel in 10 hours?
miles
Answer:
A= 560mph, B=5,600miles in 10 hours
Step-by-step explanation:
If you divide 3,360 by 6 to get the mph for part a, you’ll then multiply that by 10 to get part b.
3,360 / 6= 560
560*10=5,600
