Responder:
Número total de bolas = 245/23
Explicación paso a paso:
Dado que:
Bolas blancas = 1/5
Bolas negras = 1/7
Bolas rojas = 7
Sea el número total de bolas = x
Bolas blancas = 1 / 5x
Bolas negras = 1 / 7x
Por tanto, total;
(x / 5 + x / 7 + 7) = x
((7x + 5x) / 35) +7 = x
(12x / 35) + 7 = x
7 = x - 12x / 35
7 = (35x - 12x) / 35
7 = 23 veces / 35
245 = 23x
x = 245/23
Which graph shows y = 2x -1/2
Answer:
Did u ever find out the answer? Im on the same website and I need it too
Graph (C) shows the equation of line y = 2x -1/2.
What is equation of line?A line's equation is an algebraic way of expressing the collection of points that make up a line in a coordinate system.
The many points that collectively make up a line on the coordinate axis are represented as a group of variables (x, y) to create an algebraic equation, also known as an equation of a line.
The given equation of line is,
y = 2x - 1/2 (1)
Standard equation of the line is y = mx + c
By comparison, slope of the line (1),
m = 2
To plot graph, find x and y intercept,
x intercept of line at y = 0,
0 = 2x - 1/2
2x = 1/2
x = 4
y intercept of line at x =0,
y = -1/2
The graph of the line is represented here.
Correct answer is option (3).

Eight years ago, Rudi thought that he was making a sound investment by buying $1000 worth of Pro Sports Management stock. Unfortunately, his investment depreciated steadily, losing 15% of its value each year. whats the multiplier and an equation for this
Answer:
The multiplier is 0.85
The depreciation equation is;
P = I(0.85)^t
Step-by-step explanation:
Let us write an equation for the depreciation
It is in the form;
P = I( 1 - r)^t
where P is the present value
I is the value at which it was bought
r is the depreciation percentage = 15% = 15/100 = 0.15
t is the number of years after byte year it was bought
so we can have;
P = 1000(1 - 0.15)^t
P = 1000(0.85)^t
The
multiplier is 0.85

8x = 8+2(x-10)+3x hurry please ill give you brain lesst
Answer:
x = -4
Step-by-step explanation:
8x = 8 + 2(x-10) + 3x
simplify
8x = 8 + 2x - 20 + 3x
simplify again
8x = 5x - 12
subtract 5x from both sides
3x = -12
divide both sides by 4

A jwelery supply shop buys silver chains from a manufactorer for c dollars each and then sells the chains at a 57% markup
write the markup as a decimal
Answer: The expression for the retail price of a silver chain is 1.4c.
Step-by-step explanation:
Let the amount of jewelry be c dollars.
Rate of mark up = 40%
So, Amount of mark up would be
[tex]\frac{40}{100}[/tex] times c
= 0.4c
So, Amount after mark up would be
c+0.4c
=1.4c
Answer: The expression for the retail price of a silver chain is 1.4c.

what is the value of MB between A and B?
Answer:
MB = 26
Step-by-step explanation:
AM = 2x - 3
MB = 5x + 1
AB = 21 - (-12)
= 21 + 12
= 33
According to the question M is between A and B. So,
[tex] \rm \longrightarrow AB = AM + MB \\ \\ \rm \longrightarrow 33 = (2x - 3) + (5x + 1) \\ \\ \rm \longrightarrow 2x - 3 + 5x + 1 = 33 \\ \\ \rm \longrightarrow (2x + 5x) + (1 - 3) = 33 \\ \\ \rm \longrightarrow 7x - 2 = 33 \\ \\ \rm \longrightarrow 7x - 2 + 2 = 33 + 2 \\ \\ \rm \longrightarrow 7x = 35 \\ \\ \rm \longrightarrow \dfrac{7}{7} x = \dfrac{35}{7} \\ \\ \rm \longrightarrow x = 5[/tex]

Graph the first equation, which has slope = −3 and y-intercept = 2, graph the second equation, which has slope = 1 and y-intercept = 4, and find the point of intersection of the two lines.
Graph the first equation, which has slope = −2 and y-intercept = 3, graph the second equation, which has slope = −4 and y-intercept = −1, and find the point of intersection of the two lines.
Graph the first equation, which has slope = 2 and y-intercept = −3, graph the second equation, which has slope = 4 and y-intercept = 1, and find the point of intersection of the two lines.
Answer:
C. Graph the first equation, which has slope = −2 and y-intercept = 3, graph the second equation, which has slope = −4 and y-intercept = −1, and find the point of intersection of the two lines.
The two equations are in slope intercept form which is y = mx + b where m is the slope and b is the y-intercept.
In the first equation (y = -2x + 3), -2 is the slope since it is the coefficient. "b" is 3 since it is the constant of the equation.
In the second equation (y = -4x -1), -4 is the slope is the coefficient, and the y-intercept is -1 since it is the constant.
To solve the equations graphically, graph them and find the point where they intersect.

because 2y° and 59° are 2 opposing angles ⇒ 2y° = 59° ⇔ y = 29.5°
we also have: (3x - 4)° = 59° ( because of 2 parallel lines)
⇔ 3x = 59 + 4 = 63

find the number of ways the digits 0,1,2 and 3 can be permuted to give rise to a number greater than 2000
You have to have the 2 or 3 as the first digit.
After that, the other 3 digits can be done in 3! = 6 ways.
So, the total is 2*3! = 12
The number of ways the digits 0,1,2 and 3 can be permuted to give rise to a number greater than 2000 is 9.
What is permutation?A permutation is a word that describes the number of ways things can be ordered or arranged.
Given are numbers, 0,1, 2, 3
We asked for numbers greater than 2000, so those numbers will start either from 2 or 3.
2 _ _ _ = 3! = 6
3 _ _ _ = 3!/2! = 3
Hence, total possible ways are 6+3 = 9
