Which number line represents all the values of x for the equation x^2=16?

If product of x and 5.2 is 104 then the value of x is 20.

Two or more expressions with an Equal sign is called as Equation.

Given that  product of x and 5.2 is 104

We have to find the value of x

product of x and 5.2 is 104 can be mathematically written as below

5.2x=104

To find value of x

divide both sides by 5.2

x=104/5.2

x=20

Hence, if product of x and 5.2 is 104 then the value of x is 20.

The algebraic expression for the scenario is 'd = 55t', where 55 (miles per hour) is the constant, and 't', which represents time in hours, is the variable. This expression is used to calculate the distance traveled by a car.

The subject of your question is algebra, particularly involving the concept of linear equations. In this scenario, you're looking to determine how far a car will travel given a certain speed and number of hours. Your constant in this case will be the speed of the car, which is 55 miles per hour. The variable is the time in hours, which we can denote by 't'. Hence, the algebraic expression representing this scenario would be d = 55t where 'd' represents the distance traveled by the car. The distance is calculated by multiplying the constant speed by the variable time.

The multiplications between (-1.15) and  3.2 will be negative of 3.68.

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

WE need to find the multiplications between (-1.15) and  3.2

We now that when multiplying, when the signs are different, the result will be negative.

(-1.15) x 3.2 = -3.68

Therefore, the multiplications between (-1.15) and  3.2 will be negative of 3.68.

Hope it helps

The change in elevation from the beginning of Suzi's hike to the end is 98 feet, as calculated by the difference in starting and ending elevations: (-127) - (-225) = 98 feet.

To calculate the elevation change, we subtract the elevation at the start of the hike from the elevation at the end of the hike. Suzi started at -225 feet below sea level and ended at -127 feet below sea level.

To find the change in elevation, we perform the following calculation:

Write down the starting elevation: -225 feet.

Write down the ending elevation: -127 feet.

Subtract the starting elevation from the ending elevation: (-127) - (-225).

Simplify the equation by adding: -127 + 225 = 98 feet.

Therefore, the change in elevation from the beginning of Suzi's hike to the end is 98 feet. The positive result indicates an increase in elevation, even though Suzi is still below sea level at the end of her hike.

since the exponent is 4, move the decimal place 4 places to the right

 so 2.13786 x 10^4 = 21378.6

The student can check the accuracy of their answer by substitifying their solution back into the equation. If both sides of the equation are equal after the substitution, then the solution is correct and 4 * 3 + 6 does in fact equal 18 in this case.

The subject of your question is to solve a simple equation and you want to check your answer. The equation you're talking about can be expressed as 4x + 6 = 18, where x is the number you're trying to find. You said you believe x = 3, and we can check that by substituting 3 for x in the equation and seeing if both sides match.

On the left side of the equation, 4x + 6 would become 4 * 3 + 6, which equals 12 + 6 = 18. The right side of the equation is also 18, so your answer of x = 3 is correct!

Substituting your answer back into the equation is a solid strategy to check your answers in mathematics.

Answer:

[tex]x=\frac{3j-n}{4k+7m}[/tex]

Step-by-step explanation:

We have the expression [tex]3j=4kx+7mx+n[/tex] and we have to solve for x, this means that we have to clear x.

Then first we are going to subtract n in both sides of the equation,

[tex]3j=4kx+7mx+n\\3j-n=4kx+7mx+n-n\\3j-n=4kx+7mx[/tex]

Now in the right side we can apply common factor x.

[tex]3j-n=(4k)x+(7m)x\\3j-n=x(4k+7m)[/tex]

For the last step divide both sides of the equation in (4k+7m),

[tex]3j-n=x(4k+7m)\\\\\frac{3j-n}{4k+7m}=\frac{x(4k+7m)}{(4k+7m)} \\\\\frac{3j-n}{4k+7m}=x[/tex]

Then,

[tex]x=\frac{3j-n}{4k+7m}[/tex]

The square of any number is simply that number multiplied by itself. Thus the square of 410 is 410 multiplied by 410, which equals 168100.

The concept being asked here is the squaring of exponentials. 'To square' a number encompasses multiplying that number by itself. Hence 41 to the second power, or 41 squared, equals 1681 as the question states. By the same logic, to find the square of 410, we would multiply 410 by itself. That calculation will give the result as 168100. The square of 410 is 410 multiplied by 410, which equals 168100. Thus, the square of 410 equals 168,100.

Aling Luding will need 23.75 meters of cloth to make 25 pillowcases, with each pillowcase requiring 95 cm of cloth. We convert the total centimeters to meters by dividing by 100.

To calculate the total amount of cloth Aling Luding needs to make 25 pillowcases, with each pillowcase requiring 95 cm of cloth, we need to perform a simple multiplication. We multiply the number of pillowcases by the length of cloth needed per pillowcase.

Therefore, the calculation will be:

25 pillowcases  imes 95 cm per pillowcase = 2375 cm.

However, we often measure fabric in meters, so we need to convert centimeters to meters. There are 100 cm in a meter, so:

2375 cm \/ 100 = 23.75 meters.

So, Aling Luding needs 23.75 meters of cloth in total to make 25 pillowcases.
