Answer:

x=-260

Step-by-step explanation:

1/4x-2/5x=39

Find a common denominator:

5/20x-8/20x=39

Combine:

-3/20x=39

Multiply both sides by -20/3:

x=39(-20/3)

x=-780/3

x=-260

Answer:

The equation e = 4 h can be used to describe this situation.

Jonah earns $20 to babysit for 5 hours.

Step-by-step explanation:

When Jonah babysits one hour, he earns $7.50.

looking at the graph we see at 1 hour he earns 4 dollars false

The equation e = 4 h can be used to describe this situation.

The slope is 4   so y = 4x   e = 4h  would also work   true

Jonah earns $20 to babysit for 5 hours.

Using our equation from above

e = 4*5 = 20   true

The number of hours Jonah works depends on how much he earns.

This would be false

The dependent variable is on the y axis.  The amount he earns depends on how much he works

Answer:

208 dollars

Step-by-step explanation:

necklaces- 24 x 5 = 120

bracelets- 8 x 3 = 24

anklets- 16 x 4 = 64

added together- 208

Nina makes a total of $208.

$208 money does she make.

Here, we have,

To calculate how much money Nina makes, we need to determine the total revenue from selling bracelets, necklaces, and anklets.

The revenue from selling bracelets can be calculated by multiplying the number of bracelets sold (8) by the price per bracelet ($3):

Revenue from bracelets = 8 * $3 = $24

The revenue from selling necklaces is found by multiplying the number of necklaces sold (24) by the price per necklace ($5):

Revenue from necklaces = 24 * $5 = $120

The revenue from selling anklets can be calculated by multiplying the number of anklets sold (16) by the price per anklet ($4):

Revenue from anklets = 16 * $4 = $64

To find the total revenue, we sum up the revenue from each type of item:

Total revenue = Revenue from bracelets + Revenue from necklaces + Revenue from anklets

Total revenue = $24 + $120 + $64 = $208

Therefore, Nina makes a total of $208.

Step-by-step explanation:

x=y

they are the same numbers

Joe's Painting: 20x + 100 = y

Steve's Painting: 15x + 120 = y

x = hours worked

y = total income

We can find when the two equations intersect by making them equal to each other. That means we put an equal sign in the middle. So, it would look something like this:

20x + 100 = 15x + 120

First, we have to move the 100 by subtracting it from both sides.

20x = 15x + 120 - (100)

20x = 15x + 20

Then, we need to move the 15x by subtracting it from both sides.

20 - (15x) = 20

5x = 20

Lastly, we need to divide 5 from both sides.

5x = 20/5

x = 4

Therefore, Joe and Steve would have to work for 4 hours in order for their models to be equal to each other.

Answer:

Y=17

X=17√2

Step-by-step explanation:

1) This triangle is a right isosceles triangle. You know this because it is marked in that way.

2) In an isosceles triangle, the legs are congruent. That means, if one leg is x, then the other leg will also be x.

- In this case, (y) will be 17 because the other leg is also 17.

3) According to pythagorean theorem, a^2 + b^2 = c^2. The hypotenuse is directly across the 90º angle. So, in this case, knowing that both legs are 17,

you can write  17^2 + 17^2 = c^2

(c = x) because i'm just substituting the values.

So now, solve it. You will get

289 + 289 = c^2

c^2 = 578

now just square root 578.

(remember c = x)

You get that x = √578 = 17√2

Answer:

22/50?

Step-by-step explanation:

Answer:

22/50

Step-by-step explanation:

This is an experimental probability. This means that it is based on the experiment given to us. We know that out of the 50 times that she has pulled a tile out of the bag, she has gotten orange 22 of those times. Based on those results we can say that the probability of her choosing an orange again is 22/50. Or 44%.

Answer:

Step-by-step explanation:

No.  y = - (x + 2) + 4 is not even a quadratic.

If you want a quadratic you must indicate squaring:  y = - (x + 2)^2 + 4.

This IS in vertex form; the vertex is at (-2, 4).

The answer is [tex]\boxed{7},[/tex] where [tex]a=5[/tex] and [tex]b=2.[/tex]

Solution sketch:

Apply the Pythagorean theorem to find [tex]EC[/tex] and [tex]AE,[/tex] which you then use to find [tex]AD[/tex] and [tex]BC.[/tex] Apply Heron's formula to [tex]\triangle ABC[/tex] to find that its area is 10, and then use [tex][ABC]=\frac{(AB)(CF)}{2}[/tex] (base times height over 2) to finish by solving for [tex]CF.[/tex].

Answer:

D

Step-by-step explanation:

By definition, any two lines that are parallel must have the same slope, since they are angled the same amount (they travel the same amount up over a certain sideways distance). Hope this helps!

The required slope of the red line is equal to 5. Option D is correct.

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
The slope of the parallel line is always equal, so as of the given condition if green and red lines are parallel then the slope of the red line is equal to the slope of the green line.
The slope of the red line = slope of the green line
The slope of red line = 5

Thus, the required slope of the red line is equal to 5, Option D is correct.
