Answer:

(B)

Step-by-step explanation:

2 + 3x + 2 is just another way to write 3x + 4, so therefore, no matter what x is, they will always name the same number.

Hope this helps :)

Answer:

B

Step-by-step explanation:

We need to find if 3x+4 is equal to 2+3x+2

To do this let's set up an equation           3x+4 = 2+3x+2

Lets reorganize the terms                          3x+4 = 3x+2+2

We know that 2+2 is 4 so lets simplify      3x+4 = 3x+4

Subtract 4 from both sides                         3x = 3x

Finally divide both sides by 3                      x = x

As you can see after isolating x, we get x=x signifying thast whatever number I rep[lace x with, they will always be equal.

Ex.  2=2    6=6        944=944        -233= -233

Therefore B is the correct answer

Answer:

Therefore, the solution to the equation 12v = 48 + 4v is v = 6.

Step-by-step explanation:

To solve for v in the equation 12v = 48 + 4v, you can start by simplifying the equation by moving all the v terms to one side and all the constant terms to the other side:

12v - 4v = 48

Simplifying the left side of the equation gives:

8v = 48

To solve for v, you can divide both sides of the equation by 8:

v = 6

Therefore, the solution to the equation 12v = 48 + 4v is v = 6.

Answer:

Step-by-step explanation:

12v = 48 + 4v

Your first step is to subtract v from both sides:
8v = 48

Then, you divide each sides by 8 which gives you:

v = 6

That's your answer!

Answer:

255.7cm^2  to 1 dp

Step-by-step explanation:

Area of a full circle is:  pi R^2

= pi 10^2

= 100 x pi

= 314.159265 cm^2

We then divide by 314.159265/ 360 = 0.872664625 cm^2

And multiply by 293 x 0.872664625 = 255.690735 cm^2

= 255.7cm^2

Answer:

A = plane

B = whale

C = sunken ship

Step-by-step explanation:

The given vertical number line is modelling the positions of objects and animals in relation to sea level.

Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.

From inspection of the given number line:

We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.

We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.

Answer:

Step-by-step explanation:

The equation y=7x+1 is written in slope intercept form. That would be:

y=mx+b

m is the slope

b is the y intercept, or where the line first is seen on the y axis.

Because b=1, the y intercept is 1.

Because m=7, the slope is 7.

STEP 1: GRAPH THE Y INTERCEPT.

Since b=1, the line crosses the y intercept when y=1. So graph y=1 on the coordinate plane.

STEP 2: GRAPH THE SLOPE

Do this by going up 7, then right 1. Because 7 is a positive number, you go up.

Step-by-step explanation:

($1238-$1039)×12=$2388

4+7x-2

========================================================

Explanation:

Combine the like terms in choice A to find that:

Therefore, choice A simplifies to 7x-6.

Choice B on the other hand simplifies to 7x+2 since 4-2 = 2.

The expressions 7x-6 and 7x+2 don't match up, which means the answer is either choice A or choice B.

--------------

Let's simplify choice C.

Choice C simplifies to 7x-6 which matches with choice A. In other words, choices A and C are equivalent expressions. We can rule out choice A and go with  choice B   as the final answer.

For the sake of completeness, let's simplify choice D

8x-x-6 = 7x-6

This shows choice D matches with A and C.

Answer:

Elsa earned the most

Ben earned the least

Step-by-step explanation:

E = Elsa's speed

B = Ben's speed

C = Cal's speed

The combined speeds are:

E + B = 1/11

E + C = 1/9

B + C = 1/9.9

If we add up all three equations:

2B + 2C + 2E = 10/33

B + C + E = 5/33

If we subtract each of the first three equations from the total equation, we can find the individual speeds.

C = 5/33 − 1/11 = 2/33

B = 5/33 − 1/9 = 4/99

E = 5/33 − 1/9.9 = 5/99

Ben and Cal paint together for 1 hour.  The fraction of the wall they paint is:

(1/9.9) × 1 = 10/99

Elsa, Ben, and Cal all paint together for the next 4.5 hours.  The fraction of the wall they paint is:

(5/33) × 4.5 = 15/22

Ben and Elsa then finish the job.  The amount of wall left is 1 − 10/99 − 15/22 = 43/198.  So the time it takes is:

(43/198) / (1/11) = 43/18 hours

The fraction of the wall that Ben paints is:

(4/99) (1 + 4.5 + 43/18) = 284/891

The fraction of the wall that Cal paints is:

(2/33) (1 + 4.5) = 1/3 = 297/891

The fraction of the wall that Elsa paints is:

(5/99) (4.5 + 43/18) = 310/891

Answer:

Ben earned the most as 6 of 16.5 as a percentage = (6*100):16.5 =36.36%

We check with Elsa and she earned the least as (5*100):16.5 =30.31%

Cal earned the average as 5.5 of 16.5 as a percentage = (5.5*100):16.5 =33.33%

Step-by-step explanation:

E + B = 11hrs    

E + C = 9hrs

B+C = 9.9 hrs

Lets say the house was 100ft sq

if E took 5.5 hrs

B took 5.5hrs  we would have 11

C took  3.5 hrs  we would have 9hrs for E+C

B took 5.5 hrs + 3.5hrs we are 0.9hrs short and see that B would need to take 0.9 more which means E works 0.9hrs less and shares 0.4 less with C having 0.5 less which gives B an extra 0.4 instead of 0.9

This equates to B: 5.9  , C:  3.9 ,  E: 5.1  

We can change to B: 6  , C: 3.94  , E: 5.4  

= E+B =  11.4  = 11  

= E+C = 8.99 = 9  

= B+C = 9.94  = 9.9

Percentages of fixed net pay when B: 6  , C: 3.94  , E: 5.4 = 6+ 3.94+ 5.4 = 100

Time when 15.34 hrs = 100% if working same rate changes to 16.5hrs to account for the hours given 8am-1.30pm 8am-1.30+ 9am-1.30+ =  minimum 1hr more = 2pm

Cal worked 8 am till 1.30 pm = 5.5hrs = 1.66hr extra

Ben worked 8am till 2pm = 6 hrs = 0 hr extra  together worked 11.5hrs

Elsa worked 9am till 2pm = 5 hrs = -0.4hr less

11.5+ 5 = 16.5 This equals 16.5hrs = 100%

Ben earned the most as 6 of 16.5 as a percentage = (6*100):16.5 =36.36%

Cal earned the average as 5.5 of 16.5 as a percentage = (5.5*100):16.5 =33.33%

We check with Elsa and she earned the least as (5*100):16.5 =30.31%   is the same as 100-69.67%

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

The amount of money raised and the number of students who attended the dance will be directly proportional to each other, meaning both are positively dependent on each other. This type of a relationship is called a linear relationship, which can be represented by a type of graphical method called the "linear graph".

To accurately represent the data, on the x axis you need to plot the the number of students attending the dance; and on the y axis you need to plot the amount raised and you'll obtain a positive slope of 10.

The starting point of the graph would have the coordinates (0,100) or x = 0 and y = 100, because even if there are no students attending the event, the decoration cost of 100 dollars would still have to be paid.

The equation for the same should be written as: Amount of money raised = 10 x no. of students + 100
