To find the value of x in a system of equations, you can use the substitution or elimination method. In this case, x = 2 is the solution.
To find the value of x in the system of equations x − 2y = 2 and 3x + y = 6, we can use the method of substitution or elimination.
Substitution method:
From the second equation, y = 6 - 3x.Substitute y = 6 - 3x into the first equation: x - 2(6 - 3x) = 2.Solve for x: x - 12 + 6x = 2, 7x = 14, x = 2.Therefore, the value of x in the solution to the system of equations is x = 2.

The slant height of a cone with a surface area of 500π square feet and a radius of 15 feet is 275 feet.
Explanation:The question asks for the slant height of a cone, given that the surface area (S) is 500π square feet and the radius (r) is 15 feet. No explicit formula for the slant height is provided.
We know the formula for the surface area of a cone is S = πrl + πr², where r is the radius, l is the slant height, and π is a constant (approximately 3.14).
By rearranging this equation, subtracting the base area from the surface area and then dividing by πr, we can solve for l: l = (S - πr²)/πr.
Plugging in the provided numbers: l = (500π - π*(15 ft)²)/(π * 15 ft). Simplifying this equation gives: l = (500 - 225) ft = 275 ft. Therefore, the slant height of the cone is 275 feet.

Information about a shipment of mirrors to a local store is shown.
Of all of the medium mirrors that were shipped, how many of them were broken?
A. 68
B. 78
C. 164
D. 208
The table is an illustration of a two-way table
The number of medium mirrors that were not broken are 68
Start by calculating the number of medium mirrors
Medium = 480 - 214 - 102
Evaluate the difference
Medium = 164
From the question 96 mirrors are not broken.
So, the number of broken mirror is:
Broken = 164 - 96
Evaluate the difference
Broken = 68
Hence, the number of medium mirrors that were not broken are 68

What point on the unit circle corresponds to an angle of 173º
The point on the unit circle that corresponds to an angle of 173º is approximately (-0.9917, 0.1288), derived by converting the angle to radians, then calculating the cosine and sine for the x and y coordinates respectively.
Explanation:To find the point on the unit circle that corresponds to an angle of 173º, we first need to convert the angle from degrees to radians. We use the conversion factor of π/180 radians per degree, so 173 degrees is equal to (173)*(π/180) = 3.02 radians.
On the unit circle, the x-coordinate of a point corresponds to the cosine of the angle, and the y-coordinate corresponds to the sine of the angle. In this case, the x-coordinate would be cos(3.02) ≈ -0.9917, and the y-coordinate would be sin(3.02) ≈ 0.1288.
So, the point on the unit circle that corresponds to an angle of 173º is approximately (-0.9917, 0.1288).

The product P of two consecutive natural numbers, the first of which is N
The product of two consecutive natural numbers, with the first being [tex]\( N \),[/tex]is [tex]\( N \times (N + 1) \).[/tex]
The product [tex]\( P \)[/tex] of two consecutive natural numbers can be expressed as the product of a number and its consecutive number. So, if the first number is [tex]\( N \),[/tex] then the second number would be [tex]\( N + 1 \).[/tex] Therefore, the product [tex]\( P \)[/tex] can be written as:
[tex]\[ P = N \times (N + 1) \][/tex]
Expanding this, we get:
[tex]\[ P = N^2 + N \][/tex]
This represents the product of two consecutive natural numbers where [tex]\( N \)[/tex] is the first number.
Ming says that 0.24 > 1414 because 0.24 = 2424
Final answer:
To compare numbers, we look at their values from left to right. In this case, 1414 is greater than 0.24 due to the magnitude of the numbers.
Explanation:
The student's statement is incorrect. To compare numbers, you look at the digits from left to right, so 0.24 is less than 1 as it's closer to zero. Meanwhile, 1414 is a much larger number because it's in the thousands range.
Therefore, 1414 > 0.24, not the other way around. The student's reasoning based on the equality with 2424 is inaccurate in the context of comparing these two numbers.

5.6 times what equals to -19.04
The given equation can be rearranged as a division problem: -19.04 divided by 5.6. The solution to this is -3.4. Thus, 5.6 times -3.4 equals -19.04.
Explanation:To answer the question, we must find the unknown variable in your given equation, where you are multiplying a number (5.6) by some unknown figure to get -19.04. This type of math problem is a division problem arranged differently. Instead of saying '5.6 times what equals to -19.04', we can rearrange it to say '-19.04 divided by 5.6 equals what'.
To get the answer, simply divide -19.04 by 5.6, which equals -3.4. So 5.6 times -3.4 equals -19.04.

The airport garage charges $5 to park for the first hour and then $3.50 an hour for any additional hours. Ben paid $57.50 to park there one day when he flew to another city. How many hours was he parked at the airport?
Final answer:
Ben was parked at the airport for a total of 16 hours, after calculating the initial cost for the first hour and then dividing the remainder by the hourly rate for additional hours.
Explanation:
The student's question asks how many hours Ben was parked at the airport, given that the parking cost is $5 for the first hour and $3.50 for each additional hour, with a total fee of $57.50.
First, we subtract the initial $5 from the total cost to determine the cost of additional hours:
$57.50 - $5 = $52.50 for additional hours
Next, we divide the remaining cost by the hourly rate for additional hours to find the number of additional hours Ben parked:
$52.50 ÷ $3.50/hour = 15 hours
Finally, we add the first hour to the additional hours to calculate the total hours parked:
15 hours + 1 hour = 16 hours
Thus, Ben was parked at the airport for a total of 16 hours.

georgia is making sock puppets.each pair of sock puppets cost $2 georgia bought six pairs of sock puppets.how much did she spend
Georgia spent a total of $12 on six pairs of sock puppets, with each pair costing $2.
Georgia is calculating the total cost of sock puppets she purchased. The cost per pair is $2, and she bought six pairs. To find out how much she spent, we need to multiply the cost per pair by the number of pairs she bought.
Calculation:
Cost per pair of sock puppets = $2
Number of pairs = 6
Total cost = Cost per pair * Number of pairs
Total cost = $2 * 6
Total cost = $12
Therefore, Georgia spent $12 on sock puppets.

To find the product of [tex]3x^{3y}[/tex] and [tex]5x^{2y}[/tex], multiply 3 and 5 to get 15, then add exponents of x (3 and 2) and y (1 and 1, because y = [tex]y^{1}[/tex]) to get [tex]15x^{5y^{2} }[/tex].
Explanation:
The student's question involves the multiplication of exponentials. When multiplying variables with exponents, we multiply the coefficient (numerical part) and add the exponents of like bases.
Given the expression [tex]3x^{3y}[/tex].[tex]5x^{2y}[/tex], we multiply the coefficients (3 and 5) and add the exponents of like bases (“3” for x and “1” for each y, since no exponent means 1).

Fred Johnson's total insurance premium is $1,200. His employer pays 60% of the total premium. How much does Fred pay? $480 $720 $2,000 $3,000
Answer: First option is correct.
Step-by-step explanation:
Since we have given that
Amount of Fred Johnson's total insurance premium = $1200
Percentage of total premium his employer pays = 60%
Remaining percentage of total premium he pays is given by
[tex]100\%-60\%=40\%[/tex]
So, amount of insurance premium Fred Johnson pay is given by
[tex]\frac{40}{100}\times 1200\\\\=40\times 12\\\\=\$480[/tex]
Hence, First option is correct.

Answer:
13+2+9=2+13+9
[29(14)]+45=[14(29)]+45
Step-by-step explanation:
The equivalent expressions 13 + 2 + 9 = 2 + 13 + 9 and [29(14)] + 45 = [14(29)] + 45 demonstrate the commutative property, according to which the order in which numbers are added or multiplied does not change the result.
Explanation:The commutative property in mathematics is the property that states the order in which numbers are added or multiplied does not change the result. So, looking at the given options, the expressions that demonstrate the commutative property are:
13 + 2 + 9 = 2 + 13 + 9 [29(14)] + 45 = [14(29)] + 45
The other options do not represent the commutative property.
The operation 8 + 0 = 8 is an instance of identity property of addition because any number added to zero gives that number. The expression 9(8 + 45) = 9(8) + 9(45) is an application of the distributive property (where a(b + c) = ab + ac), and 29(14 + 45) = 14(29) + 45 is not a valid mathematical equation since it doesn't balance equally on both sides.Learn more about Commutative Property here:https://brainly.com/question/5637942
