How to solve the equation: -2(x-2)+4=2x
Answer:
x = 2
Explanation:
Given the expression
-2(x-2)+4=2x
you are to find the value of x that will make the equation true
Open the bracket
-2x+4 + 4 = 2x
-2x + 8 = 2x
-2x - 2x = -8
-4x = -8
x = -8/-4
x = 2
Hence the solution to the equation is x = 2

Write two angles coterminal to 5pi/7, one that’s positive and one that’s negative
As given by the question
There are given that the angle:
[tex]\frac{5\pi}{7}[/tex]Now,
To find a positive and negative coterminal angle, add and subtract 2pi to the given angle.
Then,
[tex]\begin{gathered} \frac{5\pi}{7}+2\pi=\frac{5\pi+14\pi}{7} \\ =\frac{19\pi}{7} \end{gathered}[/tex]And,
[tex]\begin{gathered} \frac{5\pi}{7}-2\pi=\frac{5\pi-14\pi}{7} \\ =\frac{-9\pi}{7} \end{gathered}[/tex]Hence, the positive and negative angles are shown below:

ANSWER
[tex]AB=12\text{ }mm[/tex]EXPLANATION
We want to find the length of AB.
The length of AB represents the radius of the circle since it is the distance from the center of the circle to the circumference.
We are given that the diameter of the circle is 24 mm. The radius of a circle is half of its diameter, hence, the radius of the circle is:
[tex]\begin{gathered} r=\frac{24}{2} \\ r=12\text{ }mm \end{gathered}[/tex]Therefore, the length of AB is:
[tex]AB=12\text{ }mm[/tex]That is the solution.
The Wycoffs are planning their next family night. They always have dinner out somewhere and then do something fun together. There are 2 adults and 7 children in the family. Each family member is allowed 3 meal suggestions, and each child is allowed 4 activity suggestions. Assuming no family members choose the same thing, how many different family night possibilities are there?
Answer
756 possible family nights
Step-by-step explanation
There are 9 family members ( = 2 adults + 7 children)
Given that each family member is allowed 3 meal suggestions, then there are 9x3 = 27 meal suggestions.
Given that each child is allowed 4 activity suggestions, then there are 4x7 = 28 activity suggestions.
Each family night consists of 1 meal and 1 activity. Therefore, there are 27x28 = 756 possible family nights

The cost (c), in dollars, charged by a car rental agency is calculated using the equation c = 12 +0.29m, where m represents the distancetraveled in miles.Calculate the distance traveled for the cost of $56. 37.
The distance taveled is 153 miles
Explanation:The cost function is given as:
c = 12 + 0.29m
Given cost of $56.37, the distance m is obtained from the following equation:
56.37 = 12 + 0.29m
0.29m = 56.37 - 12
0.29m = 44.37
m = 44.37/0.29

a fruit package company produced peaches last summer whose weights were normally distributed with the mean 14 ounces and standard deviation 0.4 ounce. among a sample of 1000 of those peaches about how many could be expected to have any weights of more than 12.6 ounces?round to the nearest whole number as needed
Let x be the random representing the weights of the peaches produced by the company. Since the weights are normally distributed and the population mean and standard deviation are known, we would apply the formula,
z = (x - mean)/standard deviation
From the information given,
mean = 14
standard deviation = 0.4
For the weights to be more than 12.6 ounce, the equation would be
[tex]z\text{ = }\frac{(12.6\text{ - 14)}}{0.4}[/tex]z = -3.5
Looking at the normal distribution table, the probability corresponding to the z score of - 3.5 is 0.00023
Since we want to determine propability for the weights greater than 12.6 ounce, the required probability would be
1 - 0.00023 = 0.99977
Given that the total number of peaches is 1000, the number of peaches expected to have weights more than 12.6 ounce is
0.99977 * 1000 = 999.77
Rounding to the nearest whole number, it becomes 1000
The number of peaches expected to have weights more than 12.6 ounce is approximately 1000

Answer:

Since their measures sum up to 180 degrees, the numbers 3 and 4 in the following figure are supplementary.Complementary angles are two angles with a combined angle of 90 degrees, whereas supplementary angles have a combined angle of 180 degrees. Angles sum right angle, but supplementary and complementary angles don't have to be nearby (sharing a vertex and side, or close to each other).Two angles are said to be supplementary angles because they combine to generate a linear angle when their sum is 180 degrees.

Using only a compass can you find points in a plane that are the same distance from points A and B
You can locate points on a plane (or more specifically, a line segment) that are equally spaced apart from points A and B using a compass.
How can you use a compass to make a locus of points that are equally spaced between A and B?
Draw a straight line AB=7 cm using a ruler.Draw an arc from A using a compass, and then draw another arc that intersects the first one at the point where it crosses AB.From A to the arc, draw a straight line, then extend it to M.Measure 5 cm with a ruler and write AC on the result.We have the required triangle by joining BC.From point C, draw an arc that cuts over AC and BC. From the point where it cuts across AC and BC, draw an arc that cuts across each other. Finally, draw a line that extends from point C to the junction of the two arcs.The same holds true for A as well as O, the intersection of the two lines.Draw a circle with O as the center. This circle will serve as our incircle. Next, draw a perpendicular from O to AB. This perpendicular will serve as the radius.AN is the set of points in our locus that are equally spaced from the lines AB and AC.We must create an incircle, which is a circle inside of a triangle. We can accomplish this by creating an angle bisector from two sides; the intersection point will serve as the incentre. The center of the required circle.
The location where two points are equally distant from one another is known as the angle bisector.

...
If the carpet costs $19.05 per square yard, it would cost $857.25 to carpet a rectangular floor that is 27 feet by 15 feet.
How are calculations made per square yard?Multiplying the length by the breadth in feet and dividing by 9 yields the square yards (SQYDS). A square yard has a surface area of 9 square feet.Given: A floor rectangle with dimensions of 15 feet by 27 feet.
We need to determine the cost to carpet the floor if the carpet costs $19.05 per square yard.
Area of rectangular floor = 15 × 27
= 405 square feet
We know that,
1 square yard = 9 square feet
So,
405 square feet = 405/9 = 45 square yards
Cost to carpet 1 square yard = $19.05
Cost to carpet 45 square yards = 19.05 × 45
= $857.25
