Danny charges $30 for 2 hours of swimming lessons, Martin charges $72 for 4 hours of swimming lessons. Who offers a better deal?

Answer:

the equation should be c=768/s or c s=768.

Step-by-step explanation:

This situation involves inverse variation, so the equation will either take the form c=6/3 or the form cs=k.

To write a general equation for this situation, find the value of k. Use the form cs=k and the point (128,6) since the container can fill 128 cups holding 6 ounces each.

cs=k

(128)x(6)=k

768=k

Using 768 for k, the general equation is c=768/s or cs=768.

The equation for the number of cups for a specific size can be written as c = 768/x.

A linear equation is a equation that has degree as one.

To find the solution of n unknown quantities n number of equations with n number of variables are required.

The amount of drinks carried by each cup is 6 ounces.

And, the total number of cups are 128.

Then,the total amount of drink is 128 × 6 = 768 ounces.

Suppose the number of cups be c.

And, the size of each cup be x.

The following equation can be written for the number of cups as,

c = 768/x

Hence, the equation that describes the number of cups for the given case is c = 768/x.

Answer:

x=-2

Step-by-step explanation:

Let's solve your equation step-by-step.

5(x+6)+11=25−3x

Step 1: Simplify both sides of the equation.

5(x+6)+11=25−3x

(5)(x)+(5)(6)+11=25+−3x(Distribute)

5x+30+11=25+−3x

(5x)+(30+11)=−3x+25(Combine Like Terms)

5x+41=−3x+25

5x+41=−3x+25

Step 2: Add 3x to both sides.

5x+41+3x=−3x+25+3x

8x+41=25

Step 3: Subtract 41 from both sides.

8x+41−41=25−41

8x=−16

Step 4: Divide both sides by 8.

8x

8

Answer:

23 gallons of water

Step-by-step explanation:

People use water to​ cook, clean, and drink every day. An estimate of 33.9​% of the water used each day is for cooking. If a family uses 67.8 gallons of water a day for cooking​, how many gallons do they use every​ day?

This is calculated as:

33.9 % × 67.8 gallons of water

= 0.339 × 67.8 gallons of water

= 22.9842 gallons of water

Approximately = 23 gallons of water

Therefore, 23 gallons of water are used everyday for cooking

Answer:

The walkway around the pool makes the entire outer dimensions (outer border)  

x+9+2x3=x+15  and  x+8+2x3

hope this helps!  could i get brainliest plz?

The expressions to represent the dimensions of the outside border of the walkway is  (x + 12) meters for the length and (x + 11) meters for the width.

Given area : [tex]x^2 + 17x + 72[/tex]

The factored form of the polynomial is:

[tex]x^2 + 17x + 72[/tex]  = [tex]x^2 + 8x+9x+72[/tex]

                      = x(x+8)+9(x + 8)

                          =(x + 9)(x + 8)

So, the dimensions of the pool are (x + 9) meters and (x + 8) meters.

The length of the walkway = 3 meters wide

So, the length is added to each side of the pool.

Dimensions of the outside border of the walkway:

Length: (x + 9) + 3 = x + 12 meters

Width: (x + 8) + 3 = x + 11 meters

Therefore, the dimensions of the outside border of the walkway are

(x + 12) meters for the length and (x + 11) meters for the width.

Answer:

p = 1

Step-by-step explanation:

4 - 5(p + 3/5) = -4

Find P

4 - 5(p + 3/5) = -4

4 - 5p -15/5 = -4

4 - 5p - 3 = -4

-5p + 1 = -4

-5p = -4 - 1

-5p = -5

p = -5/-5

p = 1

Check:

4 - 5(p + 3/5) = -4

4 - 5(1 + 3/5) = -4

4 - 5 - 15/5 = -4

4 - 5 - 3 = -4

4 - 8 = -4

-4 = -4

Answer:

x ≤ 72

He needs to sell 72 more bags.

Step-by-step explanation:

Cho has sold 28 bags and his goal is to sell 100 bags write an inequality to show how many more bags he needs to sell

Let x represent the number of bags he needs to sell

28 + x ≤ 100

x ≤ 100 - 28

x ≤ 72

Therefore he needs to sell 72 more bags.

1. Find slope.

slope(m)

[tex] = \frac{y2 - y1}{x2 - x1} \\ [/tex]

[tex] \frac{2 - 3}{10 - 0} = \frac{ - 1}{10} [/tex]

2. Substitute any point. (either (0,3) or (10,2) to find the y-intercept (b)

y=mx+b

3=-1/10+b

b=31/10 or 3.1

so the final answer is

y= - 1/10 + 31/10 or y= - 0.1 + 3.1

The surface area of the cone is 56.52 in².

An object's surface area is the total area that all of its surfaces occupy. Many 3D shapes in geometry have various surface areas, which are simply calculable using the formulas.

As per the given diagram:

slant height of the cone (l) = 7 inch

radius of the cone (r) = 2 inch

For the surface area of the cone:

= πr(l+r)

= (22/7) × 2 × (7 + 2)

= (396/7)

= 56.52 in²

Hence, the surface area of the cone is 56.52 in²
