What steps would you take in order to solve the equation 38 = 6x – 16? subtract 16 and then divide by 6 divide by 6 and add 16 add 16 and divide by 6 multiply by 6 and add 16

Answers

Answer:

x = 9

Step-by-step explanation:

38 = 6x - 16

Situate the x to one side -6x = -16-38

-6x = -54

-x = -9

x = 9

Isolate x by adding 16 to both sides of the equation to get 54=6x.

Then, divide birth sides of the equation by 6 to get 9=x, or x=9.

Answers

Answer:

x = -8 and y= 8

(-8,8) is the answer

Answer:

(2,4) (-4,16)

Step-by-step explanation:

Subtract  2 x  from both sides of the equation.

y = 8 − 2 x

Substitute  8 − 2 x  for  y  into  x ^2 − y = 0  then solve for  x .

x = 2 , − 4

Substitute  2  for  x  into  x 2 − y = 0  then solve for  y .

y=4

Substitute  − 4  for  x  into  x 2 − y = 0  then solve for  y .

y=16

Equation form

x = 2 , y = 4

x = − 4 ,  y = 16

Point B is the center of the circle shown, and the length of arc AC is 8π. What is the area of the circle?

Answers

Answer:

[tex]A=324\pi \text{ units}^2\approx1017.88\text{ units}^2[/tex]

Step-by-step explanation:

The formula for arc length is:

[tex]\stackrel{\frown}{A}=2\pi r(\frac{\theta}{360}})[/tex]

Where Θ is measured in degrees.

We know that the arc length is 8π when the degree is 80. So, substitute 8π for A and 80 for Θ:

[tex]8\pi=2\pi r(\frac{80}{360})[/tex]

Divide both sides by 2π:

[tex]4=r\frac{80}{360}[/tex]

Simplify the fraction:

[tex]4=\frac{2}{9}r[/tex]

Multiply both sides by 9/2:

[tex]r=18[/tex]

So, the radius is 18.

Now, we can find the area of the circle. The formula for the area of a circle is:

[tex]A=\pi r^2[/tex]

Substitute 18 into r:

[tex]A=\pi (18)^2[/tex]

Simplify:

[tex]A=324\pi \text{ units}^2\approx1017.88\text{ units}^2[/tex]

Organic Whole Wheat Flour Sells in bags Weighing 2.915 Kg A. How much flour is this when rounded to the nearest tenth B. How much flour is this when rounded to the nearest tenth Explain your thinking

Answers

Answer:

2.9 kg

Step-by-step explanation:

If you round 2.915 to the nearest tenth, it would be 2.9. this is because the number to the right of the 9 (1) is below 5.

The amount of flour after rounded to the nearest tenth will be 2.91 kg.

What is rounding off?

Rounding numbers refers to changing a number's digits such that it approximates a value. The provided number is more simply represented by this value. For instance, 700,000 rather than 698,869 could be used to express a town's population.

Given that;

Organic Whole Wheat Flour Sells in bags Weighing 2.915 Kg.

Now,

Since, Organic Whole Wheat Flour Sells in bags Weighing 2.915 Kg.

We know that;

When we round to the nearest tenth we see the right digit of tenth place if it is less than 5 then write same as number but if the number is greater than 5 then add one on the tenth place number.

Hence,

The amount of flour after rounded to the nearest tenth = 2.9

Because,  1 < 5

Thus, The amount of flour after rounded to the nearest tenth = 2.9 kg
