Answer:
x=5
Step-by-step explanation:
add 3 to both sides of the equation: -3+3=0 12+3=15 simplified: 6x=3x+15 then subtract 3x from both sides of the equation. simplified: 3x=15
then divide both sides by 3. simplified: x=5

In a high school stadium there are 750 seats. There are twice as many seats in the home
section as there are in the visitor section. Which system of equations could be used to
determine the number of seats in the home section, h, and the number of seats in the
visitor section, v, in the stadium?
PLEASE HELP HURRY PLEASEEE
Answer:
There are 250 home section and 2(250) = 500 visitor section.
Step-by-step explanation:
Let there are h number of seats in the home section and v is the number of seats in the visitor section.
h+v = 750 ...(1)
There are twice as many seats in the home section as there are in the visitor section.
v = 2h ...(2)
From equations (1) and (2).
h+2h = 750
3h = 750
h = 250
Hence, there are 250 home section and 2(250) = 500 visitor section.
Lin's sister has a checking account. If the account balance ever falls below zero, the bank charges her a fee of $5.95 per day. Today, the balance in Lin's sister's account is -$2.67. In 14 days, Lin's sister will be paid $430 and will deposit it into her checking account. If there are no other transactions besides this deposit and the daily fee, will Lin continue to be charged $5.95 each day after this deposit is made? Explain or show your reasoning.
Answer: No, the bank will not keep charging her the $5.95 after the deposit is made.
Step-by-step explanation:
Today, Lin's sister's balance is -$2.67
She gets charged $5.95 per day.
There are 14 days until she can charge some money in the bank account, so the bank will charge $5.92 14 times
So her balance after 14 days will be:
Balance = -$2.67 - $5.95*14 = -$85.97
When she charges the $430 in the account, her balance will be:
Balance = -$85.97 + $430 = $344.03
So now she has a positive balance, which means that the bank does not charge her anymore.

Find the 6th term 9 18 36
Answer:
I think the answer is 288.
Step-by-step explanation:
The rule seems to be multiplying the past number by 2. So, 9*2=18 and 18*2=36. If we continued that rule we would then get 72, 144, and the sixth term is then 288.
hope this helps :D
Answer:
Step-by-step explanation:
This is a geometric sequence because any term divided by the previous term is a constant called the common ratio. r=36/18=18/9=2 A geometric sequence is expressed as
[tex]a_n=ar^{n-1},\text{ where a=initial term, r=common ratio, n=term number}\\ \\ a_n=9(2^{n-1})\\ \\ a_6=9(2^5)\\ \\ a_6=288[/tex]

The ages of three girls; Mandy, Dora and Ann are, 113 base 4 , 133 base 4 , and 131 base 4 respectively;
find the difference between the sum of the ages of Dora and Ann and that of Mandy
Answer:
211 base 4
Step-by-step explanation:
Sum of dora and Ann = (133+131) base 4
= 330 base 4
Difference = (330-113) base 4
= 211 base 4

Find the value of X, Z, and Y in the graph below?
9514 1404 393
Answer:
(x, y, z) = (49, 58, 122)
Step-by-step explanation:
The same-side exterior angles have a sum of 180°.
(x +9) +(3x -25) = 180
4x -16 = 180
x -4 = 45
x = 49
Vertical angles are congruent:
y = 49 +9 = 58
z = 180 -y = 122 = 3(49) -25
The values of x, y, and z are ...
X = 49Z = 122Y = 58pls answer guys if you do you get something good

what is the amount of pieces in each color
Answer:
brown = 12
yellow = 30
orange = 36
Step-by-step explanation:
let 'b' = # brown
let '18+b' = # yellow
let '3b' = #orange
add them together and set equal to 78
b + 18 + b + 3b = 78
5b + 18 = 78
5b = 60
b = 12
y = 12 + 18 = 30
o = 3(12) = 36
12 + 30 + 36 = 78
The distance between point Q and point P is 6 1/2 units .Which number could represent point Q?please help me
Answer:
[tex]Q =2\frac{1}{2}[/tex] or [tex]Q =- 10\frac{1}{2}[/tex]
Step-by-step explanation:
Given
[tex]P = -4[/tex] --- missing from the question
[tex]Distance = 6\frac{1}{2}[/tex]
Required
Determine the possible value of Q
The distance can be calculated using absolute function as:
[tex]Distance = |Q - P|[/tex]
Substitute values for distance and P
[tex]6\frac{1}{2} = |Q - (-4)|[/tex]
[tex]6\frac{1}{2} = |Q +4|[/tex]
The absolute function can then be split as:
[tex]6\frac{1}{2} = Q + 4[/tex] or [tex]-6\frac{1}{2} = Q + 4[/tex]
Make Q the subject in both cases:
[tex]Q = 6\frac{1}{2} - 4[/tex] or [tex]Q = -4 - 6\frac{1}{2}[/tex]
[tex]Q =2\frac{1}{2}[/tex] or [tex]Q =- 10\frac{1}{2}[/tex]
POPULATION In 2000, the world population was calculated to be 6,071,675,206. The world population increases at a rate of about 1.2% annually.
Write a function that represents the world population y after x years.
A) y = 6,071,675,205(1.012)^x
B) y = 6,071,675,206(1.012)^x
C) y = 6,071,605,205(1.012)^x
D) y = 6,071,675,215(1.012)^x
PLEASE HELP!!
Answer:
B) y = 6,071,675,206(1.012)^x
Step-by-step explanation:
It appears that this question asks for an exponential model that represents the population growth. I believe you could view the equation in the form y = (initial population)(rate)^x
Since the initial population is 6,071,675,206, you could substitute that in to get y = 6,071,675,206(rate)^x
Since your rate is increasing by 1.2% (0.012 in decimal form), just convert that to decimal form (knowing that 100% = 1.0, add 0.012 to get 1.012). Substitute that in to get y = 6,071,675,206(1.012)^x
Hope that helps. Feel free to let me know if it made sense.

what is the slope of the line that passes through the points (3,-2) and (9,-2)? 0 3 -3 undefined
Answer:
[tex]\boxed{\textsf{ The slope of the line is $\bf{\dfrac{3}{2}}$.}}[/tex]
Step-by-step explanation:
Two points are given to us and we need to find the slope of the line that passes through these two points . The two points are (3,-2) and (9,-2) .As we know that the slope of the line is given by [tex]\tan\theta[/tex]
Slope of a line is :-
[tex]\qquad\boxed{\boxed{ \sf Slope =\dfrac{ y_2-y_1}{x_2-x_1}=\tan\theta }}[/tex]
On using this formula we can find the slope of the line .
Putting the respective values :-
[tex]\sf\implies Slope = \dfrac{y_2-y_1}{x_2-x_1}\\\\\sf\implies Slope = \dfrac{ 9-3}{2+2} \\\\\sf\implies Slope =\dfrac{6}{4}\\\\\sf\implies\boxed{\pink{\sf Slope = \dfrac{3}{2} }}[/tex]

the graph of y = 4x^2 - 4x - 1 is shown use the graph to find estimates for the solutions of a and b
Answer:
a) -0.25 and 1.25
b) -0.5 and 1.5
Step-by-step explanation:
a) For 4x^2-4x -1 = 0
What we have to do here is to simply find he points on the x-axis in which the graph crosses it
we have this as;
approximately-0.5 and 1.5
what we are saying is that the plot crosses the x-axis at x = -0.25 and x = 1.25
ii) what we have to do here is to find the point at which y = 2
After finding this point, we trace it to the plot sideways, before we trace to the x-axis
By tracing, we have the crossing on the x-axis at these points at -0.5 and 1.5
