Solve each equation for the indicated variable. u = -3a - 3 , for a

Answers

Answer:

[tex]a = \frac{u + 3}{-3}[/tex]

Step-by-step explanation:

Isolate the variable, a. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, add 3 to both sides of the equation:

u = -3a - 3

u (+3) = -3a - 3 (+3)

u + 3 = -3a

Next, divide -3 from both sides of the equation:

(u + 3)/-3 = (-3a)/-3

a = (u + 3)/-3

[tex]a = \frac{u + 3}{-3}[/tex]  is your answer.

b) Solve the equation from Part (a). Show your work. State your solution as a complete sentence.

Answers

Answer:

G=18

Step-by-step explanation:

George-G

1/3G+G=24

4/3G=24

3/4*4/3G=24*3/4

G=18

George will be 18 years old there we can find his brothers age by dividing it by three thus 18/3=6

Answer:

George is 18 and his brother is 6

Step-by-step explanation:

let the brother's age be n then George's age is 3n ( 3 times his brother's age )

n + 3n = 24 ( sum of their ages )

4n = 24 ( divide both sides by 4 )

n = 6

and 3n = 3 × 6 = 18

George is 18 years old and his brother is 6 years old.

Table B represent a proportional relationship,where the constant of proportionality is 0.025
Step-by-step explanation:
Table B has a proportionality relationship.Treat the values in table as (x,y) values to be plotted on a graph tool.The result is a linear function with a positive slope of 0.030.The constant of proportionality is 0.030.Given;
Volume cost($)
16 1.49
20 1.59
30 1.89
Then you have ordered pairs of points as (16,1.49) ,(20,1.59), (30,1.89) .Using a graph tool, the results is a linear graph. Find the slope of the graph as;
m=Δy/Δx
For points (16,1.49) ,(20,1.59)
m=1.59-1.49/20-16
m=0.10/4 = 0.025
You notice that the expression for the relationship is;
cost($)= 0.025* Volume +1.09
y=0.025x+ 1.09 where the y-intercept is obtained by extrapolation of the line.

64° because the equation would be everything added equal to 360 so 180+90+26+x=360 so when you solve 296+x=360 , then you subtract 297 from both sides so you end up with x=64

Answer: x=64°

Step-by-step explanation:

According to the diagram, the two intersecting lines are perpendicular. That means each part is 90°. Since the left side is labelled to be 180°, we know that the sum of the right side is also 180°.

26+x+90=180            [combine like terms]

116+x=180                  [subtract both sides by 116]      

x=64°

Now, we know that x=64°.

On the other hand, we can see that 26+x=90. We can also use that to solve for x.

26+x=90                    [subtract both sides by 26]

x=64°

Answer:

  an infinite number of ways

Step-by-step explanation:

The transformation involves a series of reflections, rotations, and translations. Any reflection and translation can be described an infinite number of ways, depending on what you choose for the line of reflection (and how many reflections you choose), and how far you do each translation. Similarly, any rotation can described an infinite number of ways, depending on the amount of rotation and the chosen center point.

So, the answer to the question asked is, "You can describe the movement of the furniture an infinite number of ways."

__

One way to describe it is this:

The upper chair was translated to the right, then reflected* across the horizontal centerline. The couch was rotated 90° about the center of the room and translated upward. The coffee table was rotated -90° about its center and translated to the right.

__

* As a practical matter, a piece of furniture cannot be reflected. It can only be rotated or translated. However, the pillows in the upper chair are moved from the left arm to the right arm, so the appearance is that of a reflection. One might say the chair was rotated 180°, and the pillows were translated.

Answer:

Step-by-step explanation:

The area of the triangle is

A = 1/2 bh

We need to convert the units to match

2 ft= 24 inches

A = 1/2 ( 24*6)

A = 1/2 (144)

A =72 in^2

When dilated 6 inches *4 = 24 inches

                      24 inches *4 = 96 inches

B. Identify the slope and y intercept
(Show steps )

Answers

Answer:

Rewriting the equation in slope intercept form is: Y= -8x+4

Step-by-step explanation:

Im sure there's a faster way to solving this, but I'm just in 8th grade so I'm gonna apply what I know so far.

First of all, we know that our slope is -8... so we have y= -8x so far

From here, to find out y intercept I knew that our slope deals with all the points assigned, therefore we know that from -4 the change would be -8 so we get -12. We can also go the other way. This means that we plus 8 to get positive 4. (Side note: the change in our x value is 1 so we know that our y intercept is always dealing with a 0 in the x position) ex. (0,9) the y intercept would be 9.

To wrap things up, the slope is -8 and the y intercept is 4.

We then get Y= -8x+4

Hope this helps! :)

5. Check for reasonableness

To answer this question, let us take an example of converting from inches to centimeters.

Let us convert 10 inches to centimeters.

First step is to identify the measure to be converted which in this case it is inches that is the measure.

Second step is to write the conversion factors which is;

1 inch = 2.54 cm

Third step is to cancel the units; In this case the units to be canceled will be inches.

Fourth step is to multiply the original measurement by the conversion factor to give; 10 × 2.54 cm = 25.4 cm

Fifth step is to check for reasonableness by trying to check if using another number will give a reasonable answer.
