Answer:

x = 15

Step-by-step explanation:

Because the first part is division.... x/5, you'd want to multiply by that same number to get X alone. So you'd multiply by 5

Because of that

x = (3)(5)

x = 15

[tex]\dfrac{x}{5} =3[/tex]

Multiply both sides by 5:

With a sales tax rate of 7.8%, the tax amount is $11.72.

A sales tax rate is the percentage of the sale price of a good or service that is added on as a tax. It is usually applied to the final purchase price of a product or service and is paid by the consumer at the time of purchase.

Since the sales tax rate is 7.8% and Kiara buys a box of dirt priced at $150.24. Thus, the tax amount can be determined as follows:

Tax amount  = 7.8/100 × $150.24

Tax amount  = $11.72

Answer:

x = 140 degrees

Step-by-step explanation:

this polygon has 6 sides

to find the number of degrees of the six interior angles you can use this formula:

(n-2)*180 where 'n' equals the number of sides

(6-2)*180 = 4(180) = 720 degrees

starting with the 'x' angle and going clockwise, we have the following:

x + 90 + 104 + 123 + 155 + 108 = 720

x + 580 = 720

x = 720 - 580

x = 140

The percent error in this measurement would be 16%.

1. Calculate the difference between the measured speed and the actual speed: 5 mph - 4.2 mph = 0.8 mph

2. Calculate the percent error: (0.8 mph / 4.2 mph) x 100 = 19.05%

3. Round to the nearest whole number: 19.05% = 19%

The percent error in this measurement is 19%, which means that the measured speed was 19% higher than the actual speed.

This can be caused by a variety of factors, including the radar gun being set to an incorrect sensitivity, the speed of the ball being too high for the radar gun to accurately measure, or the radar gun not being able to accurately detect the speed of the ball due to environmental factors such as wind or lighting.

The height of the trapezoid with an area of 24cm² and base lengths of 9 cm and 7 cm is 3cm.

A trapezoid is simply a quadrilateral with at least one pair of parallel sides.

The area of a trapezoid is expressed as;

A = 1/2(a+b)h

Given that;

Plug in the values into the above formula and solve for h.

A = 1/2(a+b)h

A = 1/2(a+b)h

2A = (a+b)h

2A/(a+b) = h

h = 2A/(a+b)

h = ( 2 × 24cm² ) / ( 9cm + 7cm )

h = 48cm² / 16cm

Step-by-step explanation:

The cost of one steak burger is $4.5 and the cost of one order of fries is $2.25.

To find a cost using an equation, you need to first identify the variables involved in the equation.

Variables are values that can change, such as the price of an item or the quantity of an item. Next, you must determine the value of each variable.

Once you have all the values, plug them into the equation and solve for the cost. For example, if you have an equation where x is the cost, y is the quantity, and z is the price per item, you would plug in the values of y and z and solve for x.

The answer you get would be the cost of the item. Additionally, you can use the equation to find the cost of multiple items by changing the value of the variable y to represent the amount of items you need.

After plugging in the new values into the equation, you can solve for the cost of all the items.

Let x be the fries and y be the steak burgers.

From the following information, the equation are as follows:

2x + 3y = 18 ---------equation 1

3x + 2y = 15.75 -------equation 2

To find cost of one steak burger and cost of one order of fries,

Multiply by 3 in equation 1 and 2 in equation 2,

6x + 9y = 54 -------3

6x + 4y = 31.5 -----4

Subtracting the equation 3 and 4, we get

5y = 22.5

y = 22.5/5

y = 4.5

Substitute y=4.5 in eq 1,

2x + 3(4.5) = 18

2x = 4.5

x = 2.25

∴ The cost of one steak burger is $4.5

∴The cost of one order of fries is $2.25.

1. The equation you've provided is a linear equation in the form of y = mx + b, where m is the slope, x is the variable and b is the y-intercept.

The slope (m) of the line represented by this equation is -3/4, the y-intercept is -5/4 and x is a variable.

It is a representation of a straight line in the coordinate plane, where x and y are the coordinates. The line passes through the point (-5/4, 0) and the slope of the line is -3/4.

2.The equation you've provided is a linear equation in the form of y = mx + b, where m is the slope, x is the variable and b is the y-intercept.

The slope (m) of the line represented by this equation is -3/4, the y-intercept is -5/4 and x is a variable.

It is a representation of a straight line in the coordinate plane, where x and y are the coordinates. The line passes through the point (-5/4, 0) and the slope of the line is -3/4.

Please note that in the equation you provided -6x +8y = -10 the slope is -3/4 and y-intercept is -5/4.

Line a which passes (1, 4) has a constant of proportionality of 4.

Line b runs through (5, 2), with a constant of proportionality of 2/5.

The constant of proportionality is often represented by the letter "k" and it is used in a mathematical relationship known as a proportionality relationship. The proportionality relationship can be written as y = kx, where y and x are the two variables and k is the constant of proportionality.

This means that the value of y is directly proportional to the value of x and is equal to k times the value of x. The value of k can be found by dividing the value of y by the value of x, when the two variables are in proportion.

Line a passes through the (1, 4), therefore:

constant of proportionality = y/x = 4/1 = 4.

Line b passes through the (5, 2), therefore:

The probability that the artist chosen will be a painter or a photographer is 3/4

Probability is the function that measures the chances that an outcome of a random event will be as expected. In this way you can measure how likely it is that an event will happen.

To solve this exercise the formula and the procedure that we have to use for probability is:

probability= (achieving success / possible outcomes)

Achieving success = 7 painters + 5 photographer = 12

Possible outcomes = 7 painters + 5 photographer + 4 sculptors = 16

Applying the formula to calculate the probability we get:

probability= (achieving success / possible outcomes)

probability= 12/16

The distance travelled by Yusuf in 2 hours is 104 miles.

Speed is simply referred to as distance traveled per unit time.

Mathematically, Speed = Distance ÷ time.

Given that, Yusuf drove 156 miles in 3 hours.

confounding variables; the medical study did not control for other factors that could have caused the lower blood pressure in pet owners.

A confounding variable is an extraneous factor that can influence the results of a study. In this case, the medical study reported that people who owned pets had lower blood pressure than those who did not own pets. This led some doctors to believe that pet ownership had positive health benefits. However, further analysis of the data revealed that the pet owners in the study also exercised more and smoked less than those who did not own pets. This means that the pet ownership was not necessarily responsible for the lower blood pressure, but rather these other factors could have contributed to the results. Thus, the study lacked control for these confounding variables, which could have invalidated the results.
