¿cual es la solucion de la siguiente ecuacion (10+2x +x= -x +18)?

Answer:

175 students walk to school

Step-by-step explanation:

300+250+325=875

20% of 875 is 175

Answer:

[tex]5x+8x+10-3=72\\13x=65\\x=5\\reapplying\\5(x+2)=5*7=35\neq (\frac{72}{2}=36 )[/tex]

No it's not the Midpoint

Answer:

38.5

Step-by-step explanation:

We divide 33 by 6 to get how much each pencil is worth:

33/6= 5.5

Since we have the amount of how much each of the pencils is worth, we multiply it by 7 to know the price:

5.5 x 7= 38.5

Answer:

Step-by-step explanation:

According to the theorem, the angle measuring 110 is one-half the measure of the arc it intercepts. That means that the major arc (this arc of which I'm speaking) measures 110 * 2 = 220.

Since the outside of a circle, regardless of how big or small the circle is, has a degree measure of 360, then x = 360 - 220 so

x = 140°

Answer:

The measure of angle R is 112 degrees

Step-by-step explanation:

Using the given markings, we can see that we have an isosceles triangle

so RT is also 3x-2

Mathematically, the sum of the interior angles of a triangle is 180:

Thus;

9x + 4 + (3x-2) + (3x-2) = 180

9x + 3x +3x + 4-2-2 = 180

15x = 180

x = 180/15

x = 12

Recall; Angle R is 9x + 4

= 9(12) + 4 = 108 + 4 = 112

Answer:

35 or A

Step-by-step explanation:

This is a combinations problem because the order doesn't matter (it's a council, not like president and v.p.). C(7, 3) is 7!/(4!*3!) = 7*6*5/3*2 = 35. Hope this helps! :)

Answer:

I would say B...the cost increase for each additional hat......A. would also be partially true, because 1 hat is $35 dollars, but you pay less per hat when you buy more than one, otherwise the cost of 10 hats would be over $300.... C is also true, 9 hats is $160, but that is shown by the graph, the questions is referring to what the slope of the graph shows, not one specific point on the graph ....so I'd say B answers this specific question more accurately...and D is also partially true, because 10 hats here, is $175, but the cost of each hat is less with the more hats you buy, so if you were to buy 10 more hats and add that to the graph the next 10 would not be another $175 for a total of $350...it'd be slightly cheaper because you've ordered 20 instead of 10 and the individual cost would continue to decrease.. so although all these answers are at least partially true, I would go with B, because it answers the question most accurately regarding the slope of the line and not just the graph or price ....

Question options:

A. antitrust laws B. the provision of public goods C. consumer-protection regulations D. fractional reserve banking.

Answer:

consumer-protection regulations

Explanation:

Consumer protection regulations are regulations that protect the public or general consumers against consumption of unsafe goods. These regulations hold manufacturers accountable for production of goods that may be harmful to consumers. The Consumer Protection Act of 1987 serves the purpose of penalizing erring manufacturers so that consumers are compensated for goods that brought damage to life or property. This therefore inspires great confidence in purchase of goods and investment as consumers are backed by the law.

Answer:

u need to provide data where is data

We can't see what you are talking about. send another one.

Answer:

D

Step-by-step explanation:

you multiply by 180/pi

usually in my calculator i would always type 8(1/180) so i dont know why its saying this but u said u were gonna cry so i looked it up  and it came up w this.

"To convert from radians to degrees, multiply the radians by 180°π radians ."

Answer:

Step-by-step explanation:

x - 3y = -13

x = -13 + 3y

3 * (-13 + 3y) + 7y = 25

-39 + 9y + 7y = 25

16y = 64

y = 4

3x + 7 * 4 = 25

3x = -3

x = -1

Answer: (-1, 4)

Answer:

$180

Step-by-step explanation:

9% = 0.09

2000 * 0.09 = 180

Answer:

2.80

Step-by-step explanation:

Seeing that your scale is 1cm to 1unit to on both axes

If you add a point C then draw lines connecting them it should look like the diagram above

But the distance between A to C and B to C are both 2 cm

Giving you a right angled triangle

So using the Pythagoras theorem

AB²=AC²+BC²

AB²=2²+2²

AB²=4+4

AB²=8

Take square root of both sides

√AB²=√8

AB= 2.828

To the nearest tenth that will be

AB=2.80

Answer:2/3

Step-by-step explanation:

Answer:

X=50000/3 for x>0

Step-by-step explanation:

First get rid of log (3), toss it over exuation sign.

Then calculate the formula for double angle (sin 2x = sin²X + sin(X) x cos (X) + cos²X)

After you do that you should be able to divide everything with cos²X and get polynomial exuation which is solved by substitution method (you'll get tan and then switch it for lets say letter: t

Answer:

The cost of 1 meal, 1 night and 1 ski lesson is $ 160.

Step-by-step explanation:

Let the nights be N , meals be M, ski lesson is S.

According to the question

2 N + 3 M + S = 310.....(1)

2 N + 5 M + 2 S = 380 ..... (2)

N + 2 M = 150 .....(3)

By solving (1), (2) and (3) we get

N = $ 110, M = $ 20, S = $ 30

So, the cost of 1 night, 1 meal, 1ski lesson is

1 x 110 + 1 x 20 + 1 x 30

= 110 + 20 + 30

= $ 160

Answer:

b

Step-by-step explanation:

Answer:  x > -2, which is choice A

Notice that there's a vertical asymptote at x = -2. Think of it like an electric fence. You can get closer to it, but you can't touch it.

The answer is 129

Step-by-step explanation:

5(exponent 4)/5 = 125 +4 equals 129

I think

Answer:

129

Step-by-step explanation:

5^4 / 5   + 4

We know that a^b / a^c = a^(b-c)

5^(4-1) +5

5^3 +4

125 +4

129

Answer and Step-by-step explanation:

Everything is in the picture.

Lines are forever, so they have an arrow at each end.

Line segments have a dot at each end, so they don't go on forever.

A ray has a dot on one end and an arrow on the other, so one side goes on forever.

An angle can be acute, right, or obtuse.
