Step-by-step explanation:

The number of hours that Sam spends walking is 1 hour. And the number of hours that Sam spends biking is 2 hours.

We know that the speed formula

Speed = Distance/Time

Let 'x' and 'y' be the time when he walks and when he biking. Then the equations are given as,

x + y = 3                    ...1

4x + 12y = 20           ...2

From equations 1 and 2, then we have

4(3 - y) + 12y = 20

12 - 4y + 12y = 20

8y =  8

y = 1 hour

The value of 'x' is calculated as,

x + 1 = 3

x = 2 hours

Step-by-step explanation:

Given data

cost of 12 bottle = $9

How many bottle can $3 buy.

Given that $9 can buy 12 bottles

therefore $3 would by x bottles

cross multiply we have

9x=12*3

9x=36

divide both sides be 9

x=36/9

x=4 bottles

The cost per bottle is

9/12= $3/4

= $0.75 per bottle

if one bottle cost $0.75

the 7 bottles will cost =0.75*7

=$5.25

Answer:

4

Step-by-step expl

Since 12 bottles cost $9 then by doing

12/3=X

X=4

=$4

Raise both sides of the equation to the power of 2

Raise both sides of the equation to the power of 2 again

Simplify to get a quadratic equation.

Use the quadratic formula to find the values of x.

Step-by-step explanation:

The radical equation is expressed as:

[tex]\sqrt{x+3} - \sqrt{2x-1} = -2[/tex]

The following steps are to be followed to calculate x:

Step 1: Raise both sides of the equation to the power of 2.

[tex](\sqrt{x+3} - \sqrt{2x-1})^2 = (-2)^2\\x+3 - 2\sqrt{x+3}\sqrt{2x-1}+(2x-1) = 4\\ - 2\sqrt{x+3}\sqrt{2x-1}+x+3+2x-1 = 4\\ - 2\sqrt{x+3}\sqrt{2x-1}+3x+2 = 4\\ - 2\sqrt{x+3}\sqrt{2x-1} +3x-2 = 0\\[/tex]

Step 2: Raise both sides of the equation to the power of 2 again

[tex](-2\sqrt{x+3}\sqrt{2x-1})^2 = (2-3x)^2\\4(x+3)(2x-1) = (2-3x)^2\\[/tex]

Step 3: Simplify to get a quadratic equation.

[tex]\\4(2x^2-x+6x-3) = 4-12x+9x^2\\4(2x^2+5x-3) = 4-12x+9x^2\\8x^2+20x-12 = 4-12x+9x^2\\x^2-32x+16 = 0[/tex]

Step 4: Use the quadratic formula to find the values of x.

x = 32±√32²-4(16)/2

Each Letter Meanings:

y stands for the y-value in the order pairs on the line.

m stands for the rate of change, AKA the slope of the line.

x stands for the x-value in the order pairs on the line.

b stands for the y-intercept.

Step-by-step explanation:

Every fraction with a non-zero denominator or divisor is a rational number.

"A rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator 'p' and a non-zero denominator 'q'."

Given, a fraction has a non-zero denominator.

Therefore, the fraction is a rational number for any possible case.

An integer itself a rational number.

A decimal number is always a rational number.

A quotient is the result of dividing one number with the another.

Answer: The distance between 15 yards to 18 yards is 3 yards.

Step-by-step explanation:

Answer:

0.85, 0.86, 0.87, 0.88 or 0.89

Step-by-step explanation:

This is because, to round up a number to the nearest, the number after that number must be greater than or equal to 5. So, any of 0.85, 0.86, 0.87, 0.88 or 0.89 can be rounded to the nearest tenth since the digit after the 8 is greater than or equal to 5. So, 0.85 rounds to 0.9 to the nearest tenth, 0.86 rounds to 0.9 to the nearest tenth, 0.87 rounds to 0.9 to the nearest tenth, 0.88 rounds to 0.9 to the nearest tenth and 0.89 rounds to 0.9 to the nearest tenth.

So, any of 0.85, 0.86, 0.87, 0.88 or 0.89 can be rounded to the nearest tenth is 0.9

Answer:

4$ off every time because if you take 6×11 you get 66 from the total without anything off and then subtract 66-46 and you get 20 so you take 20÷ 5 because 1 round was his first and there was no discount on the first round so your answer is 4$ everytime

Step-by-step explanation:

This system of equations has been set up in a way that should be easier for you to do. If h=m+11, doesn't that mean you could substitute m+11 for h?

You can start by writing m+11=3m+1 then solve it as any normal equation and you get 5!

Answer:

The puck traveled a distance of 5.38 meters or 5,380 meters

Step-by-step explanation:

Here, we want to know the distance the puck traveled.

The distance from the player’s current location to the opponent’s is 55 meters

Since there are 100 centimeters in a meter, then

55 m= 55 * 100 = 5,500 centimeters

Now, we are told that the puck landed just 120 cm from the opponent’s goal

The distance traveled by the puck will be;

5,500 cm - 120 cm = 5,380 cm

The puck traveled a distance of 5,380 cm or 5.38 meters (5,380 cm to meters is calculated by just dividing by 100)

Answer:

The equation represents: A relation and a function

Step-by-step explanation:

A function is said to be a relation; however, the relation does not have to function. For a relation to result in a function, then every input gives an important output. Thus; the given information x² + y - 15 = 0 can be re-written as:

y = - x² + 15

Similarly, the equation typically illustrates a relation as well. Consequently, suppose we replace any x-value for x, then the one possible output will be for y. Hence, that is also a function.

Answer:

350 6th grade students

Step-by-step explanation:

From the question

At a school, 60% of the sixth-grade students said that hip-hop is their favorite kind of music.

Total number of sixth graders that love hip-hop = 210

Let the total number of students in the school be represented as: x

Hence,

60% × x = 210

60/100 × x = 210

Cross Multiply

60x = 210 × 100

x = 210× 100/60

x = 350 students.

Therefore, the total number of sixth graders is 350 .

Answer:

Next to 6 is 9, next to 15 is 27, and next to 3 is 5

Step-by-step explanation:

If you imagine 6 photos for every 2 minutes as a fraction and simplify it, the answer to this would be 3 photos for every 1 minute (basically 3/1). By using this unit fraction, you'll see that you're supposed multiply the amount of minutes by 3, or you can divide the # of photos by 3.

For 3 mins, you multiply that by 3 to get 9 photos.

For 9 mins, you multiply that by 3 to get 27 photos

For 15 photos, you divide that by 3 to get 5 photos.
