i hope this helps!
Answer:
3.2
Step-by-step explanation:
10= 2x + 3.6
subtract 3.6 from both sides
2x = 6.4
divide both sides by 2
x = 3.2

Square B is a dilation of square A. What is the scale factor?
This question is incomplete, the missing diagram is uploaded along this answer below.
Answer:
the scale factor is 5/4
Step-by-step explanation:
Given the data in the image below;
B is a dilation of square A, scale factor = ?
B is a dilation of square A, that is; B is a larger form of square A.
now, to get the scale factor;
The side length of Square B = 35
The side length of Square A = 28
so, the scale factor k will be;
K = 35 / 28
divided both the numerator and denominator by 7
K = 5/4
Therefore, the scale factor is 5/4
negative 5x plus 4y equals 3 i need x and y please
Answer:
x = 9
y = 12
Step-by-step explanation:
-5x + 4y = 3
x = 2y - 15
Manipulate the equations such that the coefficients of two variables are additive inverses
-5x + 4y = 3
x = 2y - 15
Inverse operations
-> 4y - 3 = 5x
-> 2y - 15 = x (*(-5))
->4y - 3 = 5x
-> -10y + 75 = -5x
Now add the equations to eliminate a variable,
4y - 3 = 5x
-10y + 75 = -5x
-6y + 72 = 0
Inverse operations
-6y + 72 = 0
72 = 6y
/6 /6
12 = y
Back solve to find (x)
2y - 15 = x
2(12) - 15 = x
24 - 15 = x
9 = x

Let's evaluate and simplify each of the given expressions:
x − 4x + 6y + (14x − 5y)
Open bracket
x - 4x + 6y + 14x - 5y
Combine like terms
11x + y
Therefore, x − 4x + 6y + (14x − 5y) is equivalent to 11x + y
3x + 3y + 2(2x − y)
Open bracket
3x + 3y + 4x - 2y
Combine like terms
7x + y
Therefore, 3x + 3y + 2(2x − y) is equivalent to 7x + y.
(5x − 3y) − x + 3x − 5y
5x - 3y - x + 3x - 5y
7x - 8y
Therefore, (5x − 3y) − x + 3x − 5y is equivalent to 7x - 8y.
4(x + y) − 3(x + y)
4x + 4y - 3x - 3y
x + y
Therefore, 4(x + y) − 3(x + y) is equivalent to x + y.
5(x + y) + 6(x − y)
5x + 5y + 6x - 6y
11x - y
Therefore, 5(x + y) + 6(x − y) is equivalent to 11x - y.

(3.5 x 10^5) : (7x10^8)
What is the answer to this question?
: is divide
Answer:
5 • 10^-4 I evaluate this by using scientific notation.
The value of the ratio (3.5 x 10⁵) : (7x10⁸) is 0.0005.
What are expressions?An expression is a sentence with at least two numbers or variables having mathematical operation. Maths operations can be addition, subtraction, multiplication, division.
For example, 2x+3
To solve (3.5 x 10⁵) : (7x10⁸), we can simplify the expression by dividing the numerical coefficients and dividing the exponents separately.
Dividing the numerical coefficients 3.5 and 7, we get:
3.5 ÷ 7 = 0.5
Dividing the exponents 5 and 8, we get:
10⁵ ÷ 10⁸ = 10⁵⁻⁸
= 10⁻³
Therefore, the simplified expression is:
0.5 x 10⁻³
We can further simplify this expression by converting 10⁻³ to a decimal:
10⁻³ = 1/1000 = 0.001
So, the final answer is:
(3.5 x 10⁵) : (7x10⁸) = 0.5 x 10⁻³
= 0.5 x 0.001
= 0.0005

what is rate and its example?In math, a rate is a ratio that compares two different portions that have distinct units. for example, if we say John types 50 words in a minute, then his rate of typing is 50 words per minute. The word "per" gives a clue that we are dealing with a rate.
rate is a ratio among measurements using different units, for example, births per year, cost per person, words per minute.
All rate problems can be solved by using the formula D = R(T), which translates to distance (D) equals rate (R) multiplied by time (T)

25. [tex]27a^{3}b^{2}[/tex]
26. [tex]3\pi x^{3}y[/tex]
Step-by-step explanation:
For 25:
[tex]A = \frac{a+b}{2} h[/tex] (area of a trapezoid)
[tex]A=\frac{11a^{2}b+7a^{2}b}{2} *3ab[/tex] (substitute terms)
[tex]= \frac{18a^{2}b}{2}*3ab[/tex] (collect like terms)
[tex]= 9a^{2}b*3ab[/tex] (reduce the fraction by crossing out 2)
[tex]= 27a^{3}b^{2}[/tex] (calculate)
For 26:
[tex]A=\pi r^{2}[/tex] (equation of area of a circle)
[tex]A=\pi (3x^{3} y)^{2}[/tex] (enter the radius)

I need help FAST!!!!
Answer:
Step-by-step explanation:
okay, so here are a few methods you can use.
___
1) +
x + 7 = 10 so because this is addition we use the reverse, subtraction. So
x - 7 = 10 - 7 and that equals to 3.
2) -
x - 2 = 10 so because this is subtraction we do the reverse, addition.
x + 2 = 10 + 2 and that equals to 12.
3) x
x times 3 = 21 because this is multiplying we divide.
x/3 = 21/3 and that would be 7.
4) /
x/2 = 10 same as above, reverse is multiplying.
x times 2 = 10 times 2 and thats 20.

. A un concierto asistieron 10000 personas , lo que representó un total de
$6600000 en ingresos por venta de boletos. Había boletos de dos precios
de acuerdo con la proximidad al escenario: general ($500) y preferente
($1300). ¿Cuántos boletos de cada tipo se vendieron?
Answer:
Número de boletos general = 8000
Número de boletos preferente = 2000
Step-by-step explanation:
Total de personas = 10000 personas
Venta total = $6600000
Ecuación para la venta total en terminos de boletos vendidos:
Número de boletos general = variable g
Número de boletos preferente = variable p
$500g + $1300p = $6600000
Simplifica la ecuación:
5g + 13p = 66000
Subsituye una de las variables usando la ecuación g + p = 10000:
g + p = 10000 => g = 10000 - p
5g + 13p = 66000 => 5(10000 - p) + 13p = 66000
Aislar la variable p:
5(10000 - p) + 13p = 66000
50000 - 5p + 13p = 66000
8p = 16000
p = 16000/8 = 2000
g = 10000 - p = 10000 - 2000 = 8000
Número de boletos general = 8000
Número de boletos preferente = 2000
Gina has one-third scale model of a three-dimensional solid, meaning that all lengths
of the model are 1/3 of the corresponding lengths in the full-size solid. If the volume of
Gina’s model is 20 cubic inches, what is the volume of the full-sized solid?
Answer:
volume is 540 inches^3
Step-by-step explanation:
The computation of the volume of the full sized solid is given below:
The length would be
[tex]\frac{a}{3}, \frac{b}{3}, \frac{c}{3}[/tex]
And, the volume is
[tex]\frac{a}{3} \times \frac{b}{3} \times \frac{c}{3}[/tex]
As the volume is given 20 cubic inches
So,
[tex]\frac{abc}{27} = 20\\\\abc = 540 inches^3[/tex]
hence, volume is 540 inches^3
