20x - (-2x) + (-16) = 6
Solve for X
Answer:
Step-by-step explanation:
x = 1
Step 1: Simplify both sides of the equation.
20x−−2x−16=6
20x+2x+−16=6
(20x+2x)+(−16)=6(Combine Like Terms)
22x+−16=6
22x−16=6
Step 2: Add 16 to both sides.
22x−16+16=6+16
22x=22
Step 3: Divide both sides by 22.

I WILL GIVE BRAINLIEST Justin is trying to find a new cell phone plan and was deciding between Verizon and AT&T. The following graph shows the rates of the phones over a period of time:
If Justin is only looking for a plan for 2 years, which is a better plan?
If Justin is looking for a plan for 7 years, which is a better plan?
What happens at point A?
Answer:
1. AT&T would be best for 2 year plan
2. Verizon would be best for 7 year plan
3. Point A is where both intersects showing the the time where both are at the same price. It also shows that after that point, is where verizon would be a better pick
Step-by-step explanation:
At&T is best for 2 year plan because for 2 years, it is less then $160 which is how much the Verizon plan costs for 2 year looking at the graph.
Verizon is best for 7 year as at the 6th year, AT&T is much more higher than Verizon meaning that if both lines keeps going on, Verizon will be cheaper for the long term
Even though Verizon may be expensive at first, after the point A, it shows that Verizon would be a better choice if you are going to use it for 3+ years.

Determine whether 33 divides the product of 2⋅3⋅7⋅11. If it does divide the product, find the quotient. If it does not divide the product, indicate the smallest factor that should be included in the product to make it divisible by 33. Please explain
Answer:
The answer would be 30
Step-by-step explanation
For positive integers: 2 ⋅ 3 ⋅ 5 ⋅ 7 ⋅ 11 = 2310 For all integers: ± ( 2 ⋅ 3 ⋅ 5 ) = ± 30 For Gaussian integers: ± 1 ± 3 i and ± 3 ± i (all combinations of signs) Explanation: A prime number is a number whose only factors are itself, units and unit multiples of itself. So in the positive integers, the first few primes are: 2 , 3 , 5 , 7 , 11 , ... So the smallest composite positive integer with the five smallest prime positive integers as factors is: 2 ⋅ 3 ⋅ 5 ⋅ 7 ⋅ 11 = 2310 If we extend our interest to include negative integers, then the smallest primes are: 2 , − 2 , 3 , − 3 , 5 , − 5 , ... So the smallest composite integers with the five smallest prime integers as factors are: ± ( 2 ⋅ 3 ⋅ 5 ) = ± 30 If we consider Gaussian integers, then the smallest primes are: 1 + i , 1 − i , − 1 + i , − 1 − i , 1 + 2 i , 1 − 2 i , − 1 + 2 i , − 1 − 2 i , 2 + i , 2 − i , − 2 + i , − 2 − i , 3 , − 3 ,... So the smallest composite Gaussian integers with the five smallest prime Gaussian integers as factor are: ( 1 + i ) ( 1 + 2 i ) = − 1 + 3 i , 1 + 3 i , − 1 − 3 i , − 1 + 3 i , 3 + i , 3 − i , − 3 + i , − 3 − i

In a certain breed of cattle, the length of gestation has a mean of 284 days and a standard deviation of 5.5 days. Thirty-four percent of gestation periods are longer than how many days, rounded to the nearest whole number?
Answer:
286
Step-by-step explanation:
Given :
Mean (m) = 284
Standard deviation (s) = 5.5
P(Z > x) = 0.34
According to the standardized formula :
Zscore = (x - m) / s
Uaing the Z probability calculator ; The Z value at P(Z > x) = 0.34 is 0.412
Hence, Zscore = 0.412
Zscore = (x - m) / s
0.412 = (x - 284) / 5.5
5.5 * 0.412 = x - 284
2.266 = x - 284
x = 2.266 + 284
x = 286.266
x = 286 (nearest whole number)
¿Cuánto pagaré por una falda que costaba 25 euros si me cargan un IVA del 21%?
porfa es para un trabajo de mate que tengo que entregar mañana
Answer:
Pagarás 30.25 euros por la falda
Step-by-step explanation:
Porcentajes
Si necesitamos agregar un porcentaje a una cantidad conocida podemos hacerlos de dos formas: Calculamos el monto del aumento y se lo sumamos a la cantidad original, o también calculamos el porcentaje aumentado y lo aplicamos a la cantidad original. Lo haremos de las dos formas:
La falda costaba 25 euros y se le cargará un 21% de IVA.
El aumento sería:
25*21/100=5.25 euros
El precio final es
25+5.25=30.25 euros
De la segunda forma. El costo original era el 100%, con el 21% de aumento sería 121%. Aplicamos el 121% al precio original para obtener:
25*121/100=30.25 euros
Se obtiene el mismo resultado: Pagarás 30.25 euros por la falda

Rama threw a paper airplane 30 times. It landed right side up 12 times and upside down 18 times. If this pattern continues and Rama throws the paper airplane one more time, what is the probability it lands right side up?
Answer:
2/5
Step-by-step explanation:
If it landed right side up 12 times out of a total of 30 times, you can write this as a fraction: 12/30.
Simplify the fraction:
12/30 divided by 6/6
2/5
This means that 2/5 is the probability.

Step-by-step explanation:
Domain is the set of x-values. We look at the graph and look for the start of x-value.
The start of domain begins at x = -4 and has no ending (positive infinity.)
Thus, our answer is x >= -4

= 10 sq ft
Area of unshaded Δ = 1/2 ·(4)·(1.9)
= 2(1.9) =3.8 sq ft
Area of shaded Δ = 10.0 - 3.8 = 6.2 sq ft

A circle has its center at (-4,8), and just touches the y-axis
Answer:i'm a bit confused
Step-by-step explanation:
are you asking a question or not?
Answer:
r = 4 units
Step-by-step explanation:
From the question it is not clear that what you want to ask. But as per me you are interested in finding the radius of the circle.
Since, circle is touching y-axis at has a center (-4, 8) so it's radius will be equal to the x-coordinate.
Here, x - coordinate is - 4
Since radius is a non negative number.
So, r = 4 units

draw the graph of y = 6 - 2x on the grid
Answer:
See attached image for the requested graph
Step-by-step explanation:
The values completed in the table and text boxes as shown, are all correct.
For the plotting of the points and drawing of the line, please see the attached image.
a. By putting the value of x one by one table can be completed
The complete table is attached below.
b. The graph is attached below.
c. solution of the given equation is x = 1.5.
Use the concept of fucntion which is defined as:
A relation between a collection of inputs and outputs is known as a function.
A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.
The given fucntion is:
y = 6 - 2x
Since we know that this equation has degree one,
Therefore, it represents the equation of a line
Now to complete the table put the value of x in the fucntion one by one:
Put x = 0:
y = 6 - 2(0)
y = 6
Put x = 1:
y = 6 - 2(1)
y = 4
Put x = 2:
y = 6 - 2(2)
y = 2
Put x = 3:
y = 6 - 2(3)
y = 0
Put x = 4:
y = 6 - 2(4)
y = -2
Put x = 5:
y = 6 - 2(5)
y = -4
b. Now with the help of this table draw the graph of this fucntion.
The graph of it is attached below.
c. To solve the equation:
6-2x = 3
Subtract 6 on both sides,
-2x = -3
Divide both sides by -2 we get.
x = 1.5
Hence,
The solution of the given equation is 1.5.

Write an equation y = kx for the table
Answer:
y = ½x
_____
k = ½
Step-by-step explanation:
[# of donuts] 2 → [total price] $1
[# of donuts] 12 → [total price] $6
[# of donuts] 3 → [total price] $1.50
[# of donuts] 7 → [total price] $3.50
Because price is the dependent variable, it is the y value. And since the price is the y variable, the donuts must be the x value.
Because the price is ½ the # of donuts, y is ½ x which means y = ½x and k = ½.
Craig read 3 books each week for 3 weeks. Joe read 4 books a week for 3 weeks. How many more books did Joe read? Choose the answer that has the correct expression and the correct answer to the question.
Step-by-step explanation:
total no. of books read by Craig = 3×3 = 9 books
total no. of books read by Joe = 4 × 3 =12 books
so the no. of books read more by Joe in comparison of Craig = 12‐9 = 3
