Answer:

Denise should plan to spend 36 minutes walking back.

Step-by-step explanation:

Let 'x' reflect the amount of time spent running in hours, then 3-x represents the time spent walking in hours.

here , we know,

           [tex]Distance= Speed \times time[/tex]

Given the values ,

[tex]Distance= 8x[/tex]  

[tex]speed=2mph[/tex]

[tex]Time=(3-x)hours[/tex]

Now , putting these values ,

[tex]8x=2(3-x)[/tex]

[tex]8x=6-2x[/tex]

[tex]10x=6[/tex]

[tex]x=\frac{6}{10}[/tex]

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

[tex]\frac{3}{5} \times 60[/tex] = 36minutes (converting hours into minutes that is 1 hour = 60 minutes )

Hence , the answer is 36 minutes .

Answer:

He paid $2.35 for each pair of socks.

An equation using the variable S is

$77.99 = 9S + (3 × $8.28) + $32

Step-by-step explanation:

Let S be the cost of a pair of socks

From the question, Mark purchase nine pairs of socks, that is, the total cost of the pairs of socks is 9S

He purchase three packages of undershirts for $8.28 each; the total cost of the three packages of shirt will be 3 × $8.28 = $24.84

and he also purchase a pair of pants for $32

Since he spent a total of $77.99, we can write that

$77.99 = 9S + (3 × $8.28) + $32

Now, we can determine S, the cost of a pair of socks

$77.99 = 9S + (3 × $8.28) + $32

$77.99 = 9S + $24.84 + $32

$77.99 = 9S + $56.84

9S = $77.99 - $56.84

9S = $21.15

S = $21.15/9

S = $2.35

Hence, he paid $2.35 for each pair of socks.

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

First you write out your inequality:

[tex]2b-7\geq -14+2b[/tex]

So first we will subtract 2b on both sides:

[tex]-7\geq -14[/tex]

Since they both canceled out each other we are now left with [tex]-7\geq -14[/tex]

So anyways let's add 7 to both sides:

[tex]0\geq -7[/tex]

I know this might be confusing but the answer is all real numbers.

Tip: Real numbers are, in fact, pretty much any number that you can think of. This can include whole numbers or integers, fractions, rational numbers and irrational numbers.

Answer:

both will give you the same amount of money, $100,000, so I would consider the fact that I'd rather only have 200 people give me money then 500. So I would say 200 people giving me $500 would be the best option

Answer:

3 gulps

Step-by-step explanation:

In this problem, f(x) = 3. Plug this into the equation:

3 = -3x + 12

Solve for x:

3 - 12 = -3x + 12 - 12

-9 = -3x

-9 / -3 = -3x / -3

3 = x

3 gulps

Answer:

The equation showing the relationship between the number of yards of yarn Paula has and the number of hats she can knit is ;

h = 42y

Step-by-step explanation:

Here, we want to write an equation;

From the question, we are told that the number of hats h that can be knitted is directly proportional to the amount of yarn in yards

Since it is a proportional relationship;

h = k * y

where k is the constant of proportionality given as 42

Hence;

h = 42 * y

h = 42y

Step-by-step explanation:

Answer:

The relation is a function.

Step-by-step explanation:

Since there is one value of  y  for every value of  x  in  ( 2 , − 7 ) , ( 3 , − 7 ) , ( 4 , − 8 ) , this relation is a function.

Answer:

$37,650

Step-by-step explanation:

Answer:

C) -0.5

Step-by-step explanation:

Since the y₁ is decreasing, that automatically makes it a negative slope, and its decreasing by 0.5, so it's C!

Answer:

15(B)

Step-by-step explanation:

all of those angles add up to 180 on a line

9 times 15 is 135

3 times 15 is 45

135+45 is 180

[tex] - 16x = - 80[/tex]

Divided sides by -16

[tex] \frac{ - 16}{ - 16}x = \frac{ - 80}{ - 16} \\ [/tex]

[tex]x = 5[/tex]
