2n

Explicación paso a paso:

Dado 2, 4, 6, 8

Enésimo término de una progresión aritmética:

Tn = a + (n - 1) d

d = diferencia común

n = enésimo término

a = primer término

Tn = 2 + (n - 1) * 2

Tn = 2 + 2n - 2

Tn = 2n

Answer:

3x+10=-5

3x=-15

x=-5

3x-12=9

3x=21

x=7

Answer:

1. [tex]x=-5[/tex]

2. [tex]x=7[/tex]

Step-by-step explanation:

First Equation

1. For the first equation, [tex]3x+10=-5[/tex] we need to move all the constants to one side.

[tex]3x+10=-5\\3x=-15[/tex]

2. Once that is done, we need to divide both sides by 3 to get [tex]x[/tex] by itself.

[tex]3x=-15\\\frac{3x}{3}=\frac{-15}{3}[/tex]

3. Now, we have our final answer.

[tex]x=-5[/tex]

Second Equation

1. For the second equation, [tex]3x-12=9[/tex] we need to move all the constants to one side.

[tex]3x-12=9\\3x=21[/tex]

2. Once that is done, we need to divide both sides by 3 to get [tex]x[/tex] by itself.

[tex]3x=21\\\frac{3x}{3} =\frac{21}{3}[/tex]

3. Now, we have our final answer.

[tex]x=7[/tex]

Answer: 1140

Step-by-step explanation:

Formula for Volume of a rectangular prism:

V= L•W•H

V= 19•6•10

The volume of the given rectangular prism is 1140 in³.

Any three-dimensional solid's volume is the area it takes up. The shapes of these solids include cubes, cuboids, cones, cylinders, and spheres. Forms come in a wide range of volumes. We have looked at a variety of three-dimensional solids and shapes, including cubes, cuboids, cylinders, cones, and more. A prism is a solid geometric shape with parallelograms for its sides and two comparable, equal, and parallel rectilinear figures for its ends.

As per the given data:

length of rectangular prism (l) = 19 in

height of rectangular prism (h) = 10 in

width of rectangular prism (w) = 6 in

To find the volume:

Volume of a rectangular prism = l × h × w= 19 × 10 × 6 in³

= 1140 in³

Hence, the volume of the given rectangular prism is 1140 in³.

Step-by-step explanation:

Answer:

[-4, ∞)

Step-by-step explanation:

We can treat this like an equation, we can subtract 13 on both sides:

-7x ≥ 28

and then we can divide both sides by -7, to get:

x ≥ -4

then we change this to interval notation:

[-4, ∞)

Answer:

a) m∠1 = 15°

b) m∠2 = 90°

c) m∠3 = 66°

d) m∠4 = 75°

e) m∠5 = 24°

f) m∠ITE = 132°

Answer: (55,9) Explanation is below.

Step-by-step explanation:

What you want to do is try to mutliply one of your equations so that either y or x will be canceled out.

Here is the example:

Say you want to get rid of x, you can multiply the first equation: x-5y=10 by -2 to match the second equation: -2x+6y=-16.

Therefore, the first equation would become -2(x-5y=10)=> -2x+10y=-20

Then subtract the first equation from the second:

 (-2x+6y= -16)

- (-2x+10y = -20)

-------------------------

=> 0x-4y= -36

Simplify and then you get y=9.

To find x, plug in y into one of the equations: x-5(9)=10 => x-45=10 => x=55

Answer:

25 students peer teacher, 22 students per tutor, 4 tutors for 81 students

Step-by-step explanation:

You need to find the unit rate,

for the teachers, to find the unit rate would be 125 divided by 5. For tutors it would be 88 divided by 4.

Then to find how many tutors you need for 81 students you would need 4 tutors because you want to divide 81 by the unit rate we got (22), and since the answer would be a decimal (3.68.....) you would need to round the whole number up to four because you cant have a decimal of a person.

Step-by-step explanation:

Answer:

Step-by-step explanation:

∠R + ∠S + ∠T = 180 {Angle sum property of triangle}

∠R + 56 + 30  = 180

         ∠R + 86 = 180

               ∠R   = 180 - 86

                ∠R =   94

Answer:

3/4 gallons of juice

Step-by-step explanation:

Katie bought 2 one-gallon bottles for a party.

2 one-gallon bottles = 2-gallon bottles of juice

We are told that:

Her guest drank 5/4 gallons of juice.

The fraction of juice leftover is calculated as:

2 gallons of juice - 5/4 gallons of juice

2 - 5/4

Lowest Common Denominator = 4

2/1 - 5/4

= 8 - 5/4

= 3/4 gallons of juice

Therefore, the fraction of juice leftover is 3/4 gallons of juice

Answer:

A

Step-by-step explanation:

Answer:

After 6 months, Casey would pay $360 to join either gym.

Step-by-step explanation:

At the first gym, the cost is $35 per month in addition to a $150 joining fee.  So, the equation based on 'x' number of months and a total cost of 'c' is:

c = 35x + 150

At the second gym, the cost is just $60 per month.  So, the equation based on 'x' number of months and a total cost of 'c' is:

c = 60x

Since you want to find the number of months 'x' it would take until Casey would pay the same amount to be a member of either gym, you can take the two equations and set them equal to each other:

35x + 150 = 60x

Subtract 35x from both sides: 35x - 35x + 150 = 60x - 35x or 150 = 25x

Divide both sides by 25: 150/25 = 25x/25 or x = 6

So, after 6 months, the cost would be same.  The find the cost, replace 'x' with 6 in one of the equations:  c = 60(6) = $360.

If he is planning on canceling in 5 months, the better option would be the second gym that costs $60 per month

I hope this helps!!!

Answer:

5

Step-by-step explanation:

17-7=10

2x5=10

Answer:

n>0

Step-by-step explanation:

the 3/5 is irrelevant for this problem, so ignore it

just focus on the -n

if n<0, the expression would be positive because negative*negative=positive

if n>0 the expression would be negative because positive*negative=negative, which is good

and it isn't 0 because 0*anything is 0 and 0 isn't positive or negative

so, the answer is 2
