Answer:
She can buy 7 Journals
Step-by-step explanation:
9 + 3x ≤ 30
Subtract 9 on both sides...
3x ≤ 21
Divide by 3 on both sides...
x ≤ 7
Hope this helps :)
Answer:
7 journals
Step-b7 y-step explanation:
In this question, we have to find how many journals she can buy with her left over money.
We know that she has a $30 gift card. We also know that she already spent $9 of it on a frame.
With this knowledge, we know that she has $21 left on her gift card.
To find how many journals she can buy, lets set up an equation where x = the amount of journals.
3x = 21
Solve for x:
3x = 21
Divide both sides by 3
x = 7
This means that she could buy 7 journals.

The following are a list of variables that will almost certainly vary across students in a large undergraduate introductory statistics course.
(a) Favorite beverage
(b) Year of birth
(c) Typing speed
(d) Handedness (e.g., left or right-handed)
(e) Age
(f) Occupation
(g) Self-report of Assertiveness
For questions 1a to 1d that follow choose the variable or variables that best represent the level of measurement.
a) Which variables would typically be measured on a nominal scale of measurement?
b) Which variable would likely be measured on an interval, but not a ratio scale?
c) Which two variables are most likely to be measured on a ratio scale?
d) As typically measured, which variable represents at least an ordinal scale of measurement, but probably not a true interval scale?
Answer:
a.) Favorite Beverage, Handedness, Occupation.
b.) Year of birth
c.) Age and typing speed
d.) Self-report of Assertiveness
Step-by-step explanation:
Scales of measurements are used in statistics to classify variables. The scale of measurement of a variable is important in statistics because it determines the kind of satisfaction analysis that should be used on it.
The four types of scale of measurement are;
1.) Norminal Scale: The normal scale is a categorical scale where variables are labeled with no specific order. No calculations can be done on this type of measurement because they do not have values and there is usually no order. Examples include;
Occupation, Favorite Beverage and Handedness.
2.) Ordinal Scale: This is used to show the order of variables. It is similar to the norminal scale with a slight difference. The ordinal scale has some form of ranking, that is some variables will be considered better or higher than others. Example include;
Self-report of assertiveness. Someone that claims to be highly assertive can be ranked above one that is just assertive.
3.) Interval Scale: This kind of measurements shows definite intervals between variables. It is like a scale where the order and the difference between variables are shown with no true zero value. Variables that fall under this category include; temperature and year of birth.
4.) Ratio Scale: This is the most accurate scale of measurement that encompasses the norminal, ordinal and interval scale of measurement. It has a zero value, shows order, interval and can still categorized. And example is the Age of students and typing speed.

Answer:
2/4 = 1/2
Step-by-step explanation:
Three consecutive integers are such that three times the smallest is 18
more than the largest. Find the integers
The value of the three consecutive integers will be 10, 11, and 12.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Three consecutive integers are such that three times the smallest is 18 more than the largest.
Let the three consecutive number be x, x + 1, and x + 2. Then the equation will be
3x = (x + 2) + 18
Simplify the equation, then the value of the variable x will be
3x = x + 2 + 18
2x = 20
x = 20 / 2
x = 10
Then the value of the integers will be
x + 1 = 10 + 1 = 11
x + 2 = 10 + 2 = 12
The value of the three consecutive integers will be 10, 11, and 12.

Which of the b values satisfy the following inequality?
5 < b - 3
choose all answers that apply
A: b=8
B: b=9
C: b=10
Answer:
b and c
Step-by-step explanation:
so to answer this one we just plug in all of the answer choices to see which ones satisfy the inequality
for a we plug in b and get 5<8-3 or 5<5 which is not true so it cant be a
next we plug in 9, 5<9-3 or 5<6 so b is a correct answer
next we plug in 10, 5<10-3 or 5<7 which is correct so c is also a correct answer

Answer:
x= 13, angle 1= 37, and angle 2= 53
Step-by-step explanation:
So you have 2x+11+1+4x=90 degrees
If you simplify it, it becomes 6x+12=90 degrees
Then, you rearrange; 6x=90-12 or 6x= 78
So then, x=13
For angle 1 its 2x+11= 37 degrees
And angle 2 is 1+4x= 53 degrees

Answer:
X=151
Step-by-step explanation:
1. 61+90= 151
-Combine the two given angles
2.180-151= 29
-Subtract the total of the two combined from 180 because all 3 angles of a triangle add up to 180.
-29 is your difference which is also the angle next to X.
3.180-29= 151
-To find angle X you subtract 29 from 180 because angle X and 29 are supplementary angles that add up to 180.
-Therefore X=151

The graph to the top right is a function.
This is a function because it a straight, connected line.
The First graph isn't a function because the lines are connected, and doesn't pass the horizontal test.
The Bottom left graph isn't a function because there are two lines and they intersect.
The Bottom right graph isn't a function because there are points but aren't connected.

A new two-year (24 months ) membership at RecPlex costa 160 . A registration fee of is front paid monthly Wita How much do new members pay each month
Answer:
The first month new members have to pay 188 dollars for the membership.
The equation is 160x+28=y
x stands for the number of months and y stands for the total cost.
For the first month (membership starts) the total cost is 188$. For the second month the total money paid would be 348$. For the third month the total money paid would be 508$. And so on you can use the equation to solve for more months. Just substitute x for the number of months you are solving for.
