Answer:

C. Julie drive 15.5 miles from her home to the grocery store. Julie drives the same path going back home. What is x, the total amount of miles traveled to the grocery store and back home?

Step-by-step explanation:

The situation in the 3rd option represents the equation, 15.5 = x/2.

Distance driven by Julie to the grocery store = 15.5 miles

Distance driven by Julie back home following the same path = 15.5 miles

Total amount of miles travelled to and fro the store, x, = 2*15.5

This means, the mile's covered going to the store or coming back home can be expressed as ½ the total amount of miles, x, covered. Which is: 15.5 = ½x

Therefore, the third option represents the equation, 15.5 = x/2.

Answer:

4th and 5th option

Step-by-step explanation:

you can easily add eqn 1 and 2 to get rid of the y term for 4th option and get rid of x term by addition as well for the 5th option

Answer:

the last two

Step-by-step explanation:

Answer:In other words, since even numbers are the multiples of 22, we can represent an even integer nn by 2k2k, where kk is also an integer. So if we have the even integers 1010 and 1616, we can rewrite them asn=2k→10=2(5)

n = 2k\, \to \,\,16 = 2\left( 8 \right)\,n=2k→16=2(8)

Step-by-step explanation:

Consecutive Even Integers

The best way to illustrate what consecutive even integers are through the use of examples. Observe that any pair of two consecutive even integers are 22 units apart. In other words, if you pick any even integer in the set of consecutive even integers then subtract it by the previous one, you will always get the difference of \bold{+2}+2 or simply \bold{2}2, written without the \bold{+}+ symbol.

Answer:

[tex]A=e^{(S+3.404/103.2)[/tex]

Step-by-step explanation:

Step one:

we are told that the relationship between the number of species and the island area is given as

[tex]S=-3.404+103.2ln(A)[/tex]-----------------1

based on any given value for either area or number of species, we can find the other.

say we want to find the land area for a given amount of specie

Step two:

we first make area A subject of the formula.

[tex]S=-3.404+103.2ln(A)[/tex]

let us isolate   [tex]ln(A)[/tex]

[tex]S + 3.404 = 103.2ln(A)[/tex]

Divide both sides by 103.2 we have

[tex](S + 3.404)/103.2 = ln(A)[/tex]

Now, exponentiate both sides using the base e.

[tex]A=e^{(S+3.404/103.2)[/tex]----------------2

for a given value of "S" we can find the area   A based on the above expression.

Answer:

The number of cases to be purchased is 2.

Step-by-step explanation:

Giving the following information:

World's Finest Coffee (Decaf) is sold by the case where one case contains 48 6-ounce packages.

First, we need to calculate how many pounds are in each case.

1 pound = 16 ounces

1 case= (48*6)/16

1 case= 18 pounds

Now, the number of cases required each month:

36 pounds = 18*x

x= number of cases

x= 36/18

x= 2

The number of cases to be purchased is 2.

Answer:

60 pieces

Step-by-step explanation:

What we know:

There are 12 inches in a foot

There are 5 6-feet lengths of ribbon

So, we simply need to multiply.

Since there are 12 inches in a foot, and we only need 6 inches for each one, we can see that she makes 2 pieces for each foot.

Multiply

2*6=12

She makes 12 pieces for each length of ribbon.

Now multiply it by 5

12*5= 60

She can make 60 pieces from 5 of these length of ribbon.

Hope this helps!

Answer:

y = -5x - 10

Step-by-step explanation:

Slope-intercept form: y = mx + b

m = slope

b = y-intercept

Now, in your case:

5x + y = -10

Move 5x (don't forget to change the signs!):

y = -5x - 10

Hope this helps!

Answer:

$12

Step-by-step explanation:

It is given that,

Rachael earned $42 for [tex]3\dfrac{1}{2}[/tex]  hours at her job today. It means,

For 7/2 hours, earning is $42

For 1 hour, we divide $42 by 7/2 as follows :

[tex]1\ h=\dfrac{42}{\dfrac{7}{2}}\\\\=\dfrac{42\times 2}{7}\\\\=\$12[/tex]

So, he will earn $12 per hour.

Answer: $22.50, but rounded to the nearest dollar its $23.00 Hope this helps :)

Step-by-step explanation: The unit rate it 1/0.75

Answer:x=9

Step-by-step explanation:

-2x+3=-15

Subtract 3 on both sides:

-2x+3-3=-15-3

-2x=-18

Divide -2 on both sides:

-2x/-2=-18/-2

x=9

If the expression (- 2x + 3) is equivalent to (- 15), then [x] is equivalent to 9.

Given is the equation as follows -

- 2x + 3 = - 15

The given equation is -

- 2x + 3 = - 15

Solving, we get -

- 2x = - 15 - 3

- 2x = - 18

 2x = 18

 x = 9

Therefore, if the expression (- 2x + 3) is equivalent to (- 15), then [x] is equivalent to 9.

answer is -1/2 .i think it will be helpful for you

Step-by-step explanation:

Let the midpoint formula be expressed as;

M(X,Y) = {x2+x1/2, y2+y1/2}

X = x2+x1/2

Y = y2+y1/2

Get x2

-3 = x2 + 1/2

-6 = x2 + 1

x2 = -6-1

x2 = -7

Get y2;

Y = y2+y1/2

8 = y2+6/2

16 = y2+6

Y2 = 16-6

y2 = 10

hence the coordinate of B is (-7, 10). Option A is correct

Answer:

$9.99 + $1.29n ≤ $50

Step-by-step explanation:

Given that:

Worth of gift card = $50

Cost of album purchased = $9.99

Cost per song to purchase = $1.29

Number of songs to purchase = n

Inequality to model the situation :

Cost of album + cost per song * (Number of songs) ≤ worth of gift card

$9.99 + ($1.29 * n) ≤ $50

$9.99 + $1.29n ≤ $50
