Tres socios tienen que repartirse 3000 dólares de beneficios. ¿Cuánto le tocará a cada uno, si el primero tiene que recibir 3 veces más que el segundo y el tercero dos veces más que el primero? Siendo el segundo representado con la letra x.
Answer:
Abrazos
Step-by-step explanation:
segundo = x
primero = (3*)segundo
tercero = (2*)primero
tercero = 2 * 3 = (6*)segundo
6x + 3x + x = 3000
10x = 3000
x = 300
segundo = 300
primero = 300 * 3 = 900
tercero = 300 * 6 = 1800
checando: 1800 + 900 + 300 = 3000

The exterior angle of each polygon and the adjacent interior angle are
supplementary.
(a) 72° (b) [tex]\displaystyle 51 \frac{3}{7} ^{\circ}[/tex] (c) 36° (d) 20° (e) 18°
Reasons:
The formula for the exterior angle of a regular polygon is, [tex]\displaystyle \theta = \mathbf{ \frac{360 ^{\circ}}{n}}[/tex]
Where;
θ = The exterior angle of the polygon
n = The number of sides of the regular polygon
(a) The number of sides in a pentagon, n = 5 sides
Therefore, for a regular pentagon, we have;
[tex]Exterior \ angle , \displaystyle \theta = \frac{360 ^{\circ}}{5} = \mathbf{{72^{\circ}}}[/tex]
The measure of the exterior angle of a pentagon, is 72°
(b) An heptagon has n = 7 sides
The measure of the exterior angle, θ, of a regular heptagon is therefore;
[tex]Exterior \ angle \ of \ a \ heptagon , \,\displaystyle \theta = \frac{360 ^{\circ}}{7} = \underline{51 \frac{3}{7} ^{\circ}}[/tex]
(c) A decagon has n = 10 sides, which gives;
[tex]The \ exterior \ angle \ of \ a \regular \ decagon, \,\displaystyle \theta = \frac{360 ^{\circ}}{10} = \underline{36^{\circ}}[/tex]
(d) The exterior angle of an 18-gon with n = 18 sides is given as follows;
[tex]The \ exterior \ angle \ of \ a \ regular \ 18-gon, \,\displaystyle \theta = \frac{360 ^{\circ}}{18} = \underline{20^{\circ}}[/tex]
(e) A regular 20-gon has n = 20 sides
The exterior angle of a regular 20-gon is [tex]\displaystyle \frac{360 ^{\circ}}{20} = \underline{ 18^{\circ}}[/tex]

Answer:
x = (-1 ±[tex]\sqrt{145}[/tex] )/8
Step-by-step explanation:
Quadratic formula: x = (-b ± [tex]\sqrt{b^{2} - 4ac}[/tex] )/(2a)
4x² + x - 9 = 0 ; General form of a quadratic is ax² +bx + c = 0
So a = 4, b = 1, and c = -9
x = -1 ±[tex]\sqrt{1^{2}-4(4)(-9)}[/tex] / 2(4)
x = -1 ± [tex]\sqrt{1 + 144}[/tex] /8
x = -1 ±[tex]\sqrt{145}[/tex] /8
x = (-1 + [tex]\sqrt{145}[/tex])/8 or x = (-1 - [tex]\sqrt{145}[/tex])/8

Sasha and Frank both have toy cars. Sasha’s car goes 875 meters in 7 minutes. Frank’s car goes 1,232 meters in 11 minutes. Who’s car goes faster and how much faster?
Answer:
Sasha's car moves 13 meters faster than Frank's car
Step-by-step explanation:
I took Sasha's 875 meters and divided it by 7minutes and got 125
Then, I took Frank's 1232 meters and divided it by 11 minutes and got 112
Finally, I subtracted 125 by 112 and got 13 meters
Answer:
125 × 11 = 1375
1375 > 1232
Sashas car goes faster then Frank's
Sashas car goes 143 meters faster then Franks

Sca = 336/12 = 28 miles/hr
Scu = 336/14 = 24 miles/hr ->
28 = B + C
24 = B - C ->

24 -28 = -2C

1. Let the four consecutive numbers be x, x+1, x+2, x+3
The sum of four consecutive number is already given to us = 70
Therefore
⇒(x)+(x+1)+(x+2)+(x+3)=70
We need to combine x as we have four x terms in the equation. The next step is to get all of the x’s on one side of the equation and all the numbers on the other side. The same rule applies – whatever you do to one side of the equation, you must do to the other side as well!
⇒4x+6=70⇒4x=64⇒x=16
So, the four numbers are 16, 17, 18 and 19.
Hence, the greatest number among them is 19.

A 4 in. by 5 in. photo is enlarged so that its width (shorter dimension) is 5 in.
What is the length of the enlarged photo?
5.25 in.
7 in.
6.25 in.
6 in.
========================================================
Explanation:
The jump from 4 inches to 5 inches is 5/4 = 1.25
In other words, 4*1.25 = 5
So we need to multiply every dimension by the scale factor 1.25 to enlarge the image. The 5 inch dimension then goes to 5*1.25 = 6.25 inches
----------
Here's another way you can solve
(old width)/(old length) = (new width)/(new length)
4/5 = 5/x
4x = 5*5
4x = 25
x = 25/4
x = 6.25

Answer:
50
Step-by-step explanation:
find a number that is 16 less than twice a number is decrease is 84
so if i get this right it is:
84 = 2x-16?
if so we do the following:
84+16 = 2x (Move the variables to one side and the numbers to the other)
100 = 2x (simplify)
50 = x (divide each side)

Write an equation that describes the nth term of the arithmetic sequence –2, –1.5, –1, –0.5, 0, 0.5, ….
Answer:
[tex]a_{n}[/tex] = 0.5n - 2.5
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 2 and d = a₂ - a₁ = - 1.5 - (- 2) = - 1.5 + 2 = 0.5 , then
[tex]a_{n}[/tex] = - 2 + 0.5(n - 1) = - 2 + 0.5n - 0.5 = 0.5n - 2.5 ← explicit equation

Given functions:
f(x) = 5x +7and
g(x) = -2x - 4Work out the composite f(g(x)):
f(g(x)) = f( -2x - 4) = 5( - 2x - 4) + 7 = -10x - 20 + 7 = - 10x - 13Answer:
f(g(x)) = -10x - 13
???? = - 8x - 13
Step-by-step explanation:
f(x) = 5x +7
and
g(x) = -2x - 4
f(g(x)) = f(-2x - 4) = 5(-2x - 4) + 7
f(g(x)) = -10x - 20 + 7
f(g(x)) = -10x - 13
f(g(x)) = -2x - 8x - 13
