The solution to the given inequality are x  ≤ 7, and (-∞, 7).

Inequality expressions

Inequality expressions are expressions that are not separated by an equal sign.

For the statement "14 less twice the sum of m and 12 is at most 24", it is expressed as:

2(x+12)-14 ≤ 24

Simplify

2x + 24 - 14  ≤ 24

2x + 10  ≤ 24

2x  ≤ 24 - 10

2x ≤ 14

Divide both sides by 2

x  ≤ 14/2

x  ≤ 7

Hence the solution to the given inequality are x  ≤ 7, and (-∞, 7).

Answers

The number of students passed is 152 and who failed is 38.

This problem is from the chapter of linear equation in one variable.

right here, it's far for the reason that the overall quantity of college students enrolled in the chemistry class is =190

And additionally the whole variety of students who passed is 4 instances the quantity of college students failed.

allow the total range of students who failed is x.

So, the number of students who passed is 4x.

According to question,

  4x + x=190

⇒5x=190

⇒x=[tex]\frac{190}{5}[/tex]

∴ x = 38

So, the number of students who failed is 38 and the number of students who passed is 152.

5. Charnita Jones earns $304.80 per week as a sales assistant. Next week she will be
promoted to assistant manager. She will then earn $332.50 per week. She is single
and claims 1 allowance. How much more will she pay in federal income tax?

Answers

Charnita Jones will have to pay $5 more in federal income tax.

According to the question we have been given that Charnita Jones

As sales assistant she earned = $304.80

After promotion as assistant manager she will earn = $332.50

Number of allowance she claims = 1

We need to find how much more she will pay in federal income tax.

For that we will first calculate how much she paid when her earning was $304.80. For this we will use the table for single persons-weekly payroll period. In that table, first we will choose the row of wages from the column number 1. We look to that row where $304.80 will lie that is the row will be $300-$310. then we will look for allowance that is 1. Thus the tax she will pay will be in column of allowance 1 and in the row of   $300-$310 is $22.

In similar way we will find out the tax she will pay when she earn $332.50 which is $27.

Difference = $27 - $22 = $5

Hence she will have to pay $5 more in federal income tax.

You average 55 miles per hour while driving to a relative's house. On the return trip, you average 50 miles per hour because of bad weather. The total driving time is 5 hours and 15 minutes. How long does each trip take?

Answers

We conclude that the frist trip takes 2.75 hours and the second one 2.5 hours.

How long does each trip take?

Remember the relation:

Distance = Speed*Time.

Here the total distance of the trip is 55mi + 50mi = 105mi

And the total time is 5 hours and 15 minutes, remember that:

60 min = 1 hour

Then; 15 min = 0.25 hours.

So the total time is 5.25 hours, with that we conclude that the average speed is:

S = 105mi/5.25 h = 20 mi/h

The first trip is 55 miles long, then the time in which it is travelled is:

T = (55 mi)/(20 mi/h) = 2.75 hours

The second trip is 50 miles long, then:

T' = (50mi)/(20 mi/h) = 2.5 hours.

We conclude that the frist trip takes 2.75 hours and the second one 2.5 hours.

a) y=-x+5
b) y=-x-2
c) y= 4x + 2
d) y=-4x-4

Answers

Answer: Any line with slope of -3/4

Reason:

Let's calculate the slope of the line through those two points

[tex](x_1,y_1) = (1,3) \text{ and } (x_2,y_2) = (4,7)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{7 - 3}{4 - 1}\\\\m = \frac{4}{3}\\\\[/tex]

The slope of the line is 4/3

Anything perpendicular to this has a slope of -3/4. I flipped the fraction and flipped the sign (from positive to negative).

So for example, the answer may be something like [tex]y = -\frac{3}{4}x+5[/tex] or [tex]y = -\frac{3}{4}x-2[/tex]. All that matters is the -3/4 out front of the x.

The perimeter of the polygon is the sum of all its sides, UV + VW + UW.

Apply the distance formula, d = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex] to find the length of each of the three sides of the polygon as shown below:

An airplane leaves Los Angeles and travels 5 hours to New York City. The return trip travels along the same route and takes 6 hours because the plane travels 99 mph slower due to a headwind. Find the distance the plane flies between the two cities.

Answers

Using the relation between velocity, distance and time, the distance of the plane ride between Los Angeles and New York is of 270 miles.

What is the relation between velocity, distance and time?

Velocity is distance divided by time, hence the following equation is built to model the relationship between these variables:

v = d/t.

For the Los Angeles to New York trip, we have that the time is of 5 hours, hence:

v = d/5.

v = 0.2d.

For the return trip, we have that the time is of 6 hours, while the velocity is 99 mph slower, hence:

v - 99 = d/6.

From the first equation, we have that:

v = 0.2d.

Replacing on the second:

0.2d - 99 = d/6.

d(0.2 + 1/6) = 99

0.3667d = 99

d = 99/0.3667

d = 270 miles.

The distance of the plane ride is of 270 miles.

The distance the man walks in 7 hours, multiplied by 7, comes out to be 24.5 miles. Alternatively, you might divide the man's distance traveled by 7, or X, to get 7 (x/7).
