Difference means subtract.

Set up the equation:

K - 8.1 > 24

Solve for k by adding 8.1 to both sides:

K > 32.1

Answer:

JL = 166 units

Step-by-step explanation:

Given that,

JL = 9x - 5, LR = 7x - 2, and JR = 35

Let us assume that, R is the midpoint of J and L. So,

JL = JR + RL

Putting all the values,

9x - 5 =35 + 7x - 2

Taking like terms together as follows :

9x-7x = 33 + 5

2x = 38

x = 19

Put the value of x inm, JL = 9x-5

JL = 9(19)-5

JL = 166

The value of JL is 166 units.

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1)[/tex]

where

m is the slope

( x1 , y1) is the point

From the question the point is (-2,-2) and slope 42

The equation of the line is

[tex]y + 2 = 42(x + 2) \\ y + 2 = 42x + 84 \\ y = 42x + 84 - 2[/tex]

We have the final answer as

[tex]y = 42x + 82[/tex]

Answer:

There are 15 mechanical pencils

Step-by-step explanation:

Recall that the probability of drawn a mechanical pencil from a larger group is given by the quotient of the number of mechanical pencils divided the total number of pencils in the sample.

so that means:

[tex]P=\frac{x}{25} \\[/tex]

being x the number of mechanical pencils and 25 the total of all pencils in the sample. Since they give as P as 3/5, we can solve for the number of mechanical pencils (x) using the equation:

[tex]P=\frac{x}{25} \\\\\frac{3}{5} =\frac{x}{25}\\x=\frac{3\,*\,25}{5} \\x=15[/tex]

So there are 15 mechanical pencils in the sample.

Answer:

Part 1: 1 mile.

Part 2: 1.32 mph.

Step-by-step explanation:

The correct speed of Mariah walks faster than Bobby, in miles per hour - 1 mile per hour.

Shaun travel in 25 minutes in the given case, when rounded to the nearest  hundredth - 7.92 miles.

Given:

speed of Mariah = 6 miles per hour

speed of Bobby = 4, 400 yards per half hour

= 8800 yards per hour

1 mile = 1760 yards

Solution:

To find out the speed difference of both Mariah and Bobby, we need to convert speeds in the same units that is mile:

=> speed of bobby = [tex]\frac{8800}{1760}[/tex]

=> speed of bobby = 5 miles per hour

as it is given 1 mile = 1760 yards

=> Now, the speed difference between Mariah and Bobby is

= 6 - 5

= 1 mile per hour.

Thus, Mariah walks faster than Bobby, in miles per hour - 1 mile per hour.

Given:

Speed of Shaun =  19 miles per hour

distance traveled in 25 minutes = ?

Solution:

To find out the traveled distance by Shaun in 25 minutes we need to find the speed per minute:

1 hour = 60 minutes

So as given, 19 miles per 60 minutes

then speed per minute = [tex]\frac{19}{60}[/tex]

= 0.316

then traveled in 25 minutes-

=> [tex]0.316*25[/tex]

=> = 7.92

Thus, Shaun travel in 25 minutes in the given case, when rounded to the nearest  hundredth - 7.92 miles.

Answer:

115°

Step-by-step explanation:

Measure of the degree of the angle represented by section B on the chart = percentage in the pie chart ÷ 100 × 360. A full circle makes 360°.

Section B represents 32% of the pie chart, therefore, number of degrees for section B = [tex] \frac{32}{100}*360 = \frac{32*360}{100} [/tex]

[tex] = 115.2 [/tex]

Section B = 115° (to the nearest whole number)

Answer:

[tex]x<-\frac{1}{2}\text{ or } x>1[/tex]

Step-by-step explanation:

So we have the equation:

[tex]|-4x+1|>3[/tex]

First, note that since the sign is greater than, this is an or inequality (not an "and" inequality). This is the student's first mistake.

So, let's solve this inequality.

Case 1:

[tex]-4x+1>3[/tex]

Subtract 1 from both sides:

[tex]-4x>2[/tex]

Divide both sides by -4:

[tex]x<-\frac{1}{2}[/tex]

The student did not flip the sign when doing this step, hence the incorrect answer.

You correctly spotted the student's mistake. Nicely done!

Case 2:

[tex]-4x+1<-3[/tex]

This is what you're missing: for this second instance, we must flip the sign to less than right away. This is because we are essentially multiplying the 3 by a negative. So, we must flip the sign in order to be correct.

Now solve. Subtract 1 from both sides:

[tex]-4x<-4[/tex]

Divide both sides by -4. Since we're dividing by a negative, flip the sign:

[tex]x>1[/tex]

So, our solutions are:

[tex]x<-\frac{1}{2}, x>1[/tex]

As mentioned previously, this is an or inequality. Therefore, our final answer is:

[tex]x<-\frac{1}{2}\text{ or } x>1[/tex]

[tex]\boxed{\bold{\huge{\boxed{x = 10}}}}[/tex]

Step-by-step explanation:

=> [tex]\sf \frac{3}{4} x + \frac{5}{6} = 5x - \frac{125}{3}[/tex]

Combining like terms

=> [tex]\sf \frac{3x}{4} - 5x = -\frac{125}{3} - \frac{5}{6}[/tex]

Taking LCM to make the denominator same

=> [tex]\sf \large{\frac{3x-20x}{4} = \frac{-250-5}{6} }[/tex]

=> [tex]\sf \frac{-17x }{4} = \frac{-255}{6}[/tex]

=> [tex]\sf \frac{17x }{4} = \frac{255}{6}[/tex]

Cross Multiplying

=> [tex]\sf 17x * 6 = 4 * 255[/tex]

=> [tex]\sf 102x = 1020[/tex]

Dividing both sides by 102

=> x = 10

Answer:

p-4

Step-by-step explanation:

Difference means subtraction

p-4

Answer: p - 4

Explanation: The word difference tells us that we need to subtract.

So the difference between p and 4 can be represented as p - 4.

Replace x, y, and z in the plane's equation with their appropriate parametric equations, then solve for t, then evaluate x, y, and z at this t to find the point P.

[tex]x+y-z=-5[/tex]

[tex](1+t)+2t-(-3t)=-5[/tex]

[tex]6t+1=-5[/tex]

[tex]6t=-6[/tex]

[tex]t=-1[/tex]

[tex]\implies x=0,y=-2,z=-3[/tex]

So the point P is (0, -2, -3).

Here, we are required to find the point, P where the lines:

intersects the plane x + y - z = -5.

The point, P where the lines intersects the plane is given by;

he point, P where the lines intersects the plane is given by;P (0, -2, 3)

Therefore, to find this point, we have to substitute for x, y and z in the equation of the plane.

Therefore, we have;

To get the coordinates of the point P where the lines intersect the plane; we can then find x, y and z by substituting t into each of their equations.

Therefore;

Therefore, the point, P where the lines intersects the plane is given by;
