Answers

The solution Jada seeks does not require any algebra but can be solved to give; x = 22.

How to solve the equation

When solving the given equation;

6 - x = -16

The solution of the equation can be obtained by subtracting 6 from both sides of the equation so that we have;

-x = -16 -6

-x = -22.

Therefore, the value of x is; 22

The equation m=40g gives the distance in miles, m, that a car can travel using g gallons of gas.
B. Write an equation that represents the inverse function: the gallons of gas as a function of distance in miles.
Question: How can I write an equation that represents the Inverse function of this problem?

Answers

[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]

Actually Welcome to the Concept of the function.

to get the inverse of the function,

let's consider that y is the function of m

hence, y = m

now, we know that m = 40g

hence, relatively, y = 40g

but to get inverse, we need gallon of gas as function of distance, hence

g = y/40,

since we know that y = m, replace it

hence the new inverse function is,

====> g = y/40

Divide both sides by -16 to isolate the x.

Jacob used an empty can for a project shown below the pills the label of the king in find the area of the label what is the approximate area of the canned label?

Answers

Answer:

B: 100.53 in²

Step-by-step explanation:

From the image of the can label shown, we can see that;

Height; h = 8 inches

Diameter; d = 4 inches

Thus, radius; r = d/2 = 4/2 = 2 inches

The can is a cylinder and the label covers only the curved surface area. Thus, formula for curved surface area of a cylinder is;

A = 2πrh

Thus;

A = (2π × 2 × 8)

A = 100.53 in²

Noah has a coupon for 30% off at his favorite clothing store . He uses it to buy a hoodie . The regular price of a hoodie is $27. What did Noah pay for the hoodie?

Answers

Answer:

$18.90

Step-by-step explanation:

The way to do percentages is actually pretty easy.

since it's taking 30% of you are left with 70%. Take 70 and divide it by 100. This gives you .70

Now what you do is you take the price of the time and multiply it by the .70

So 27.00 * .7 = 18.90

So Noah paid 18.90

In the figure MN is a midsegment of JKL. Find the value of X

Answers

Answer:

x = 9

Step-by-step explanation:

Here, we want to find the value of x

To do this, we are going to use the similar triangles principle

When two triangles are similar, the ratio of their corresponding sides are the same

The two similar triangles we shall be using are;

LMN and LJK

Thus, we have it that;

x/8.5 = x+ 9/17

17x = 8.5(x + 9)

17x = 8.5x + 76.5

17x - 8.5x = 76.5

8.5x = 76.5

x = 76.5/8.5

x = 9

describe how you would write an equationof the line in ponit slope form that goes through the points (3,-5) and (-2,10)
Please help guys <3

Answers

Answer:

10-(-5)= m(-2-3)

Step-by-step explanation:

The equation for point slope form is y- y1= m (x- x1)

You would plug in the numbers so y = y coordinate of second point which the second point is (-2,10). The y coordinate is 10. Then, since y1 = y coordinate of the first point the first point being (3,-5), the y1 is -5. You do the same thing with x and x1 being -2 and 3. So the equation should look like this:

10-(-5)= m(-2-3)

That's the answer. I hope this helps!

Perry and Jack are selling pies for a school fundraiser. Customers can buy apple pies and black berry pies. Perry sold 9 pies and 12 blackberry pies for a total of $165. Jack sold 8 apple pies and 3 blackberry pies for a total of $70. Find the cost each of one apple pie and one black berry pie.

Answers

Answer: apple pie=5

blackberry pie=10

Step-by-step explanation:

apple pies=a

blackberry pies=b

Perry sold:

9a+12b=165

Jack sold:

8a+3b=70

we have a system of equations

9a+12b=165

9a=165-12b

a=(165-12b)/9

replace in the second

8(165-12b)/9 +3b=70

after we do the multiplication we will get

1320-96b+27b=630

69b=690

b=10 dollars

a=(165-120)/9=45/9=5 dollars
