-5x divided by 2 >37
Answer: x < -14.8
Step-by-step explanation:
To solve for x, we will isolate the x-variable.
Given:
[tex]\frac{-5x}{2}[/tex] > 37
Multiply both sides of the equation by 2:
-5x > 74
Divide both sides of the equation by -5:
➜ Since we are dividing by a negative, we will flip the direction of the sign.
x < -14.8
1-8 closure property fundamentals of algebra
The closure property is defined as the completion of a collection of numbers by using arithmetic operations.
The closure property asserts that when an arithmetic operation such as addition, subtraction, multiplication, or division is done on any two numbers in the set, the response is another number from the same set.The closure property essentially asserts that when we add or multiply any two real numbers, we will obtain just one unique response, which will likewise be a real number. The commutative property asserts that the order of the numbers does not matter when adding or multiplying real numbers.For example, the closure property is true for whole numbers over addition and multiplication.To learn more about closure property, visit :

If 1 kilogram = 2.205 pounds, converting 165 pounds to kilograms and rounding to the nearest tenth gives
The value of 165 pounds is 74.8 kilograms
How to convert the metric units?The given parameter is:
1 kilogram = 2.205 pounds
Multiply both sides by 165
So, we have
165 * 1 kilogram = 2.205 pounds * 165
Divide both sides by 2.205
So, we have
165/2.205 * 1 kilogram = 2.205 pounds * 165/2.205
Evaluate the products
So, we have
74.8 kilogram = 165 pounds
Rewrite as
165 pounds = 74.8 kilogram
Hence, the value of 165 pounds is 74.8 kilograms

Find the inequality represented by the graph.
Answer:
[tex]y\le -\frac{1}{3}x + 1[/tex]
Step-by-step explanation:
The equation of the line is y = mx + b
where
m is the slope = rise/run
b = y-intercept ie where the line crosses the y-axis at x = 0
The line crosses the y axis at y = 1 so the y-intercept is 1 and the point at which the line crosses is (0, 1)
We have the equation as
y = mx + 1
To find the slope, take any two points on the line. Find the corresponding difference in the y values and divide this difference by the corresponding difference in the x values
Two convenient points are (0, 1) and (3, 0)
Slope = [tex]\frac{0-1}{3-0} = -\frac{1}{3}[/tex]
Equation of the line :
[tex]y = -\frac{1}{3}x + 1[/tex]
To find out if the inequality in the shaded region is a ≥ or a ≤ inequality, take a point in the shaded region. Determine whether the chosen point x, y values satisfy which of the following equations
[tex]y\le -\frac{1}{3}x + 1[/tex] (1)
or
[tex]y\ge -\frac{1}{3}x + 1[/tex] (2)
The point (0,0) is inside the shaded region
Plug in these values into inequality (1)
[tex]0 = -\frac{1}{3}\cdot0 + 1[/tex] = 1
Is 0 ≤ 1 ?
Indeed it is so the inequality is
[tex]y\le -\frac{1}{3}x + 1[/tex] (Answer)
The region on the opposite side of the line must be a ≥ inqeuality

A soccer ball was kicked toward the goal. the horizontal component of velocity was 22 m/s and the vertical component was 12 m/s . what is the magnitude of the resultant velocity of the soccer ball?
The magnitude of the resultant velocity of the soccer ball is 25.06 m/s .
Let the horizontal component of velocity be [tex]V_{x}[/tex] and the vertical component of velocity be [tex]V_{y}[/tex].
The magnitude of the resultant velocity will be represented by V.
So, we can write
The horizontal component of velocity = [tex]V_{x}[/tex] = 22 m/s
The vertical component of velocity = [tex]V_{y}[/tex] = 12 m/s
The relation between horizontal component, vertical component and resultant velocity is,
[tex]V^{2} = V_{x} ^{2} + V_{y} ^{2}[/tex]
On substituting value of horizontal component and vertical component, we get
[tex]V^{2}[/tex] = [tex](22)^{2} + (12)^{2}[/tex]
[tex]V^{2}[/tex] = 484 + 144
[tex]V^{2}[/tex] = 628
V = [tex]\sqrt{628}[/tex]
V = 25.06 m/s
The magnitude of the resultant velocity of the soccer ball is 25.06 m/s .

There are 18 cans of peas in a case. each can of peas is 12 ounces. if a case of peas costs $14.22, what is the unit price per can of peas? a. $0.07 b. $0.08 c. $0.79 d. $1.19 please select the best answer from the choices provided a b c d
The correct answer is option c. $0.79
As per the question:
No. of pea cans in a case = 18 cans
Weight of each can of peas = 12 ounces
Price of a case of peas = $14.22
The information regarding the weight of each can is redundant in this question and therefore, is not used for solving the question
Therefore, the formula to be used for solving:
Price per unit can of peas= (Price of a case of peas/No of pea cans in a case)
Price per unit can of peas= ($14.22/18)
The price per unit can of peas= $0.79
Hence, option c is the correct answer

Find the area of the shaded region in the first quadrant bounded by the line y=3x
The area of the shaded region in the first quadrant is: 0.75 units
What is area under a curve?The area under a curve between two points can be found by doing a definite integral between the two points.
Now,
Given:
x = 0, y = 2Curve: y = 3x - x²To find: area bounded by the given lines and curve in the first quadrant.
Finding:
Now, according to the question, the lines x = 0 and y = 2 intersect at the point (0,2).
Point of Intersection of y = 2 and y = 3x - x²:
2 = 3x - x²
=> x² - 3x + 2 = 0
=> (x - 2)(x - 1) = 0
That is, the line and the curve intersect at two points: ( 1 , 2) and (2,2). But the point that is of our importance is only (1,2).
Thus, area shaded = [tex]\int\limits^1_0 {2 - 3x +x^{2}} \, dx[/tex] = 0.75 square units.

A travel agency surveyed 70 of their clients who had visited Europe about international travel. Of the 70 clients who had visited Europe, 60 had traveled to England, France, or both. Of those 60 clients, 45 had visited England, and 50 had visited France.
c. What is the probability that a randomly chosen participant in the survey will have visited both England and France? Explain your reasoning.
The probability that a randomly chosen participant in the survey will have visited both England and France is 0.5
Given data
number of clients = 70
travelled to England , France or both = 60
travelled to England = 45
travelled to France = 50
How to find the probability that a randomly chosen participant in the survey will have visited both England and Francelet:
E represent the client that visited England only,
F represent the number of client that visited France only,
EF represent the number of clients that visited both England and France only
we have
E + F + EF = 60
45 - EF + 50 - EF + EF = 60
45 + 50 - EF = 60
95 - EF = 60
95 - 60 = EF
EF = 35
E = 10
F = 15
probability
Pr = required outcome / possible outcome
= EF / clients surveyed
= 35 / 70
= 0.5
Explanation
EF represents the number of clients that visited England and France only, and it was solved to be 35. probability is the ratio of required outcome which 35 to the possible outcome which is the total number of clients 70. The ratio gives 0.5

By using properties of right triangles, we will see that the value of x is 7.72
How to find the length of side x?In the image we have a set of right triangles, and we want to find the value of x.
Let's look at the large triangle in the left, we know that the hypotenuse measures 18 units and one angle measures 64°, with that information we can get the adjacent side (the dashed line, let's call it A) to that angle:
Cos(64°) = A/18
18*cos(64°) = A = 7.05
Now we know one of the cathetus of the smaller right triangle (the one we can see in the right side). Here we know one angle that measures 20° and the opposite to that angle measures 7.05
Then the value of x is given by the equation:
x = 7.05/sin(20°) = 7.72
We conclude that the value of x is 7.72

The percent of change is an increase in altitude of the weather balloon.
Percentage changeOriginal altitude = 100 ftNew altitude = 103 ftChange in altitude = New altitude - Original altitude
= 103 ft - 100 ft
= 3 ft
Percentage change = Change in altitude / Original altitude × 100

The slope across the values of the table are not the same, therefore, the table cannot be modelled by a linear equation.
How to Determine a Linear Equation Table?If a table can be represented by a linear equation, then the slope/rate of change between every two pairs of values on the table must be the same. If it's not, then it is not a linear equation that represents y as a function of x.
Slope/rate of change between (1, 18) and (2, 15):
