Here’s the answer:
Step-by-step explanation:
The sum of the four numbers divided by 4 is equal to the mean.
the sum/4 = mean
(12 + 50 + 48 + n)/4 = 30
(110 + n)/4 = 30
(110 + n) = 30 × 4
(110 + n) = 120
n = 120 - 110
n = 10

Hope this helps!
Answer: 9^2 or can also be read as 9 squared.The base itself is worth 9 but when you include the exponent its 81.When your solving exponents your multiplying the base by itself as many times as the exponent reads.In this case its 9x9 (2 times). The value of the base is 9 (just wanted to explain the other stuff just in case you didn't know)

Find the value of x.
Answer:
for this problem we use the sine function
[tex] \sin(x) = \frac{opp}{hyp} \\ \sin(38 ) = \frac{x}{100} [/tex]
multiply both sides of the equation by 100
[tex]100 \sin(38) = \frac{100x}{100} [/tex]
100 cancels on the right hand side of the equation
[tex]100 \sin(38) = x \\ x = 61.566\:ft[/tex]

Jen ran directly toward school at a constant velocity for 36 seconds. In one-third of that time, she ran 120 meters. What was her velocity?
Answer is 10 m/s
Step-by-step explanation:-First, we need to calculate one-third of 36 seconds :
[tex] \frac{1}{3} \times 36[/tex]
[tex] \frac{36}{3} [/tex]
[tex]12[/tex]
Now, to find velocity, let's divide the distance by time :
[tex]velocity = \frac{distance}{time} [/tex]
[tex]velocity = \frac{120}{12} [/tex]
[tex]velocity = 10 \: m/s[/tex]
Therefore, Jen's velocity is 10 m/s .

{2x + 3y = 10 -6x + y = 20 si se resuelve por el metodo de igualación ¿ cual es la igualdad que resulta si se despeja la variable y de ambas ecuaciones?
Answer:
Step-by-step explanation:
So im gonna be using the substitution method because its easier
We divide the equations into two and solve for y
-6x+y=20
We add 6x to both sides
-6x+y+6x=20+6x
y=6x+20
Now we plug in 6x+20 for y into the other equation
2x+3y=10
2x+3(6x+20)=10 We can simplify now
20x+60=10
20x=-50
take 20 from both sides so its gonna be a fraction
-5/2
We plug in -5/2 for x
y=6(-5/2)+20
y=5
]so therefore x is -5/2 and y is 5

The equality of the expression after removing y by substituting y is 2x + 21 = 10 - 6x + 7 = 20.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.
A formula known as an equation uses the same sign to denote the equality of two expressions.
In another word, the equation must be constrained with some constraints.
Given the expression,
2x + 3y = 10 -6x + y = 20
So,
2x + 3y = 20 and 10 - 6x + y = 20
To remove y we need to find y and substitute.
So by substituting,
10 - 6(20 - 3y)/2 + y = 20
y = 7
So,
2x + 21 = 10 - 6x + 7 = 20
Hence "The equality of the expression after removing y by substituting y is 2x + 21 = 10 - 6x + 7 = 20".

Al simplificar la expresión-3 (a - b) + 5b - {2a + b + [a - 3b - (2b - a) + 5b] - a}, se obtiene: - (6a + 7b)
La simplificación de expresiones algebraicas requiere la eliminación de los corchetes por sus factores de multiplicación seguido de la combinación y agrupación de los términos semejantes en suma y resta.
De la información proporcionada:
= -3 (a - b) + 5b - {2a + b + [a - 3b - (2b -a) + 5b] - a}El primer paso es abrir los soportes de adentro hacia afuera.
i.e.
= -3a + 3b + 5b - {2a + b + [ a - 3b - 2b + a + 5b] - a}= - 3a + 3b + 5b - {2a + b + a - 3b - 2b + a + 5b - a}= - 3a + 3b + 5b -2a - b - a + 3b + 2b - a -5b + aAhora, el siguiente paso es la reorganización;
= - 3a - 2a - a - a + a + 3b + 5b - b + 3b + 2b - 5b= - 6a - 7b
Por factorización;
= - (6a + 7b)
Por tanto, podemos concluir que la simplificación de la expresión anterior es - (6a + 7b).

2x - 19
Step-by-step explanation:
Perimeter = sum of sides
First let's simplify each side
We can simplify each side by using distributive property. Distributive property is where you multiply the number on the outside of the parenthesis by the numbers on the inside of the parenthesis.
2(x + 5)
Distribute by multiplying x and 5 by 2
2 * x = 2x and 2 * 5 = 10
2x + 10
1/2(4x + 8)
Distribute by multiplying 4x and 8 by 1/2
1/2 * 4x = 2x and 1/2 * 8 = 4
2x + 4
-3(2x + 11)
Distribute by multiplying 2x and 11 by -3
-3 * 2x = -6x
-3 * -33
-6x - 33
Finally add all the simplified expressions ( remember that they represent the side lengths of the triangle )
2x + 10 + 2x + 4 - 6x - 33
Combine like terms
2x + 2x - 6x = -2x
10 + 4 - 33 = -19
Perimeter: -2x - 19
What is the equation of a line through point (-12,20) that is perpendicular to the line
with equation y=-6x + 4?
Find the slope of the perpendicular line
When two lines are perpendicular, the product of their slopes is -1. This means that the slopes are negative-reciprocals of each other.
⇒ if the slope of one of the lines = - 6
then the slope of the perpendicular line (m) = ¹/₆
Determine the equation
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:
⇒ y - 20 = ¹/₆ (x - (-12))
∴ y - 20 = ¹/₆ (x + 12)
We can also write the equation in the slope-intercept form (y=mx+c) like the equation in the question by making y the subject of the equation and expanding the bracket to simplify:
since y - 20 = ¹/₆ (x + 12)
y - 20 = ¹/₆x + 2
y = ¹/₆x + 22
∴ the slope-intercept equation of the perpendicular line is y = ¹/₆ x + 22.

a teacher is making bags of different colors of modeling clay. the table shows the amount of each color she has avalible. each color will be divided into 3/16 pound bags. how many more bags of purple can she make then yellow?
Using the subtraction operation, the number of purple bags is 3 more than the number of yellow bags.
Amount of each color available :
Amount of purple color = 64 Amount of Yellow bags = 48Amount of color in pound required per bag = [tex]\frac{3}{16} [/tex]Number of Purple bags :
Amount of color required per bag × Amount of purple color
Number of purple bags = [tex]\frac{3}{16} \times 64 = 12[/tex]
Number of Yellow bags :
Amount of color required per bag × Amount of Yellow color
Number of yellow bags = [tex]\frac{3}{16} \times 48 = 9[/tex]
Now we find the difference between the number of Purple and Yellow bags :
Number of purple bags - Number of yellow bags
Difference = 12 - 9 = 3 bags
Therefore, there are 3 more purple bags than Yellow bags.
