4(4x+3)=19x+9-3x+3 what are the steps
Answers
4(4x+3) = 19x + 9 - 3x +3
parenthesis first:
4 x 4x = 16x then 4 x 3 = 12
16x + 12 = 19x + 9 - 3x + 3
combine :) :
19x - 3x = 16x then 9 + 3 = 12
16x + 12 = 16x +12
-12 -12
16x = 16x
They are the same equations lol they equal 0.
The steps of the expression are given below.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 4 (4x + 3) = 19x + 9 - 3x + 3
Now,
Solve the expression as;
The expression is,
⇒ 4 (4x + 3) = 19x + 9 - 3x + 3
⇒ 16x + 12 = 19x + 9 - 3x + 3
⇒ 16x + 12 = 16x + 12
⇒ 16x - 16x = 12 - 12
⇒ 0 = 0
Thus, The steps of the expression are given below.

y = -(5/2)x
We need points in the form (x,y).
Select different x-values to solve for y. This will create points to plot.
Let x = -2, -1, 0, 1, 2
Note: These are just random numbers I selected.
I will do two only.
Let x = -2
y = -(5/2)(-2)
y = -(5/2)(-2/1)
y = (10/2)
y = 5
Our first point to plot is (-2,5).
Let x = -1
y = -(5/2)(-1)
y = 5/2
Our next point to plot is (-1, 5/2).
Continue by letting x = 0, 1, and 2.
This will give you three more points to plot.
After plotting all points on the xy-plane, connect each point with a straight line.
Note: This line crosses the origin starting in quandrant 2 into quadrant 4..

At one college, GPA's are normally distributed with a mean of 2.7 and a standard deviation of 0.5. What percentage of students at the college have a GPA between 2.2 and 3.2?
Answers
Final answer:
About 68.27% of students at the college have a GPA between 2.2 and 3.2 because these values correspond to z-scores of -1 and +1, respectively, in a normal distribution.
Explanation:
To find the percentage of students at the college who have a GPA between 2.2 and 3.2, we will use the properties of the normal distribution. The mean GPA is 2.7 and the standard deviation is 0.5.
First, we calculate the z-scores for the GPAs of 2.2 and 3.2:
z-score for 2.2 = (2.2 - 2.7) / 0.5 = -1
z-score for 3.2 = (3.2 - 2.7) / 0.5 = +1
The z-score represents the number of standard deviations a data point is from the mean. In a standard normal distribution, the percentage of data between z-scores of -1 and +1 is approximately 68.27%.
Therefore, about 68.27% of the students at the college have a GPA between 2.2 and 3.2.

3/4x - 5y = 7
X = -4y + 12
solve by substitution ! show work pls !!
Answers
For this example, we will be plugging in (-4y+12) wherever "x" is in the other equation.
3/4 x -5y = 7
3/4(-4y+12) -5y =7
((3/4)(-4y))+((3/4)12)-5y=7
-3y+9-5y=7
-8y= -2
y=(1/4)
Now find "x" by plugging in the y-value.
x=(-4*(1/4))+12
x= -1 +12
x=11

if two lines in a plane are cut by a transversal so that a pair of consecutive interior angles is supplemantary are the lines parallel?
Answers
When two lines in a plane are cut by a transversal and a pair of consecutive interior angles is supplementary, the lines are parallel.
Explanation:When two lines in a plane are cut by a transversal and a pair of consecutive interior angles is supplementary, the lines are parallel.
We know that consecutive interior angles are located on the same side of the transversal and are inside the two lines.
Since the consecutive interior angles are supplementary, they add up to 180 degrees. This indicates that the lines are parallel.

Find the domain and range of x + y = 1. Then determine whether it is a function.
Answers
(-∞, ∞) for both.
It is a function.
The domain and the range of the equation x + y = 1 are both all real numbers. The equation is a function since each x-value corresponds to a unique y-value.
Explanation:The question is asking us to find the domain and range of the equation x + y = 1, and to determine whether it is a function.
The domain of an equation is the set of all possible x values. For this equation, we can substitute any real number for x, therefore, the domain is all real numbers.
The range of an equation is the set of all possible y-values. In this equation, for any given value of x, there will be a corresponding value of y (y = 1 - x). Therefore, the range of the equation is also all real numbers.
Whether an equation defines a function or not depends on whether each x-value corresponds to a unique y-value. For this equation, each x-value does correspond to a unique y-value, so it is indeed a function.

Given A = {18, 6, -3, -12} Determine all elements of set A that are in the solution of the inequality 2/3x + 3 < -2x -7
Answers
The values of x that make the inequality true are the answer.
Start with 18.
2/3x + 3 < -2x -7
2/3(18) + 3 < -2(18) - 7
12 + 3 < -36 - 7
15 < -43 is false, so 18 does not work.
Now do 6.
2/3x + 3 < -2x -7
2/3(6) + 3 < -2(6) - 7
4 + 3 < -12 - 7
7 < -19 is false, so 6 does not work.
Now do -3.
2/3x + 3 < -2x -7
2/3(-3) + 3 < -2(-3) - 7
-2 + 3 < 6 - 7
1 < -1 is false, so -3 does not work.
Now do -12.
2/3x + 3 < -2x -7
2/3(-12) + 3 < -2(-12) - 7
-8 + 3 < 24 - 7
-5 < 17 is true, so -12 does not work.

32 gal/min = what qt/h
Answers
32g/m = 32*60 = 1920 gallons per hour
1 gallon = 4 quarts
1920 *4 = 7680 quarts per hour
Answer: 7529.4 qt/hr
Step-by-step explanation:
The conversion used from gal to qt is:
1 gal = 4 qt
32 gal= [tex]\frac{4}{1}\times 32=128[/tex]
The conversion used from min to hr is:
60 min = 1 hr
1 min =[tex]\frac{1}{60}\times 1=0.017hr[/tex]
We are asked: 32 gal/min = ? qt/hr
[tex]32gal/min=\frac{128}{0.017}qt/hr=7529.4qt/hr[/tex]
Therefore, the conversion 32 gal/min = 7529.4 qt/hr

A jar contains 20 yellow marbles, 55 green marbles, and 25 purple marbles. You pick one marble from the jar at random. What is the theoretical probability of picking a green marble
Answers
Answer:
The theoretical probability of picking a green marble is 0.55. Step-by-step explanation:
Given : A jar contains 20 yellow marbles, 55 green marbles, and 25 purple marbles. You pick one marble from the jar at random.
To find : What is the theoretical probability of picking a green marble?
Solution :
Theoretical probability is defined as the number of favorable outcome divided by total number of outcome.
Yellow Marble = 20
Green Marble = 55
Purple Marble = 25
Total Number of marble = 20 + 55 + 25 = 100
Let G be the event of getting green marble.
So, Favorable outcome = 55
Theoretical probability of picking a green marble is
[tex]P(G)=\frac{55}{100}[/tex]
[tex]P(G)=\frac{11}{20}[/tex]
[tex]P(G)=0.55[/tex]
Therefore, The theoretical probability of picking a green marble is 0.55.
