7x + 3x - 18 = 6(x + 3)

Answers

Answer 1

Answer:

x=9, therefore 72=72

Step-by-step explanation:

I just distributed.

Answer 2

Answer:

x = 9

Step-by-step explanation:

7x + 3x - 18 = 6(x + 3) ← distribute parenthesis by 6

10x - 18 = 6x + 18 ( subtract 6x from both sides )

4x - 18 = 18 ( add 18 to both sides )

4x = 36 ( divide both sides by 4 )

x = 9

Find the x- and y-intercepts of the graph of — 7x + 8y = 40. State your answers as
whole numbers or as improper fractions in simplest form.

Answers

Answer:

x-intercept is (40/7, 0) and y-intercept is (0, 5)

Step-by-step explanation:

x-intercept ==> y-coordinate is 0 ==> y=0

y-intercept ==> x-coordinate is 0 ==> x=0

because the function is 7x + 8y = 40

when y = 0 ==> 7x = 40 ==> x = 40/7

so the x-intercept is (40/7, 0)

when x = 0 ==> 8y = 40 ==> y = 5

so the y-intercept is (0,5)

Hello!

Answer:

x=0

Step-by-step explanation:

Hope this helps!

Answer:  The correct answer is:  " x = 0 " .

________

Step-by-step explanation:

Given:  " 8 + 8x = 8 " ;  Solve for "x" ;

________

Method 1)

________

Subtract "8" from each side of the equation:

________

  → " 8 + 8x − 8 = 8 − 8 " ;

  → On the "left-hand side" of the equation:

          Note the following "like terms" :

            " +8 − 8 = 0 " ;

  →  and we are left with "8x" on the "left-hand side" of the equation.

  → On the "right hand side" of the equation:

         The "(8 − 8)" = 0 ;

________

And we are left with:

  →  " 8x = 0 " ;

________

Now, divide each side of the equation by "8" ;

   to isolate "x" on one side of the equation;

   & to solve for "x" :

________

  →  8x / 8 =  0/8 ;

to get:

  →  " x = 0 " ;

  →  which is the correct answer.

________

Method 2)

________

Given:  " 8 + 8x = 8 " ;  Solve for "x" ;

________

Subtract "8" from each side of the equation; in the following manner:

________

   8  +  8x    =    8 ;

 - 8             =   - 8 ;

_____________

   0  +  8x    =    0 ;

→ We have:  " 0 + 8x = 0 " ;

Note: On the "left-hand side" ; we have:

                 " 0 + 8x " ;

  We can simplify this to "8x" ; since the "addition property of zero" states that when "0" is added to any value; the resulting value does not change.

Now, we can bring down the "0" from the "right-hand side" of the equation;

And we can rewrite our equation as:

________

   → " 8x = 0 " ;

Now, divide each side of the equation by "8" ;

   to isolate "x" on one side of the equation;

   & to solve for "x" :

________

  →  8x / 8 =  0/8 ;

to get:

  →  " x = 0 " ;

  →  which is the correct answer.

________

Method 3)

________

Given:  " 8 + 8x = 8 " ;  Solve for "x" ;

________

Divide each side of the equation by "8" ;

________

  → " [tex]\frac{(8 + 8x)}{8} =\frac{8}{8}[/tex] " ;

________

To solve:

________

Note: On the "right-hand side" of the equation:

________

Take note that: " [tex]\frac{8}{8} =[/tex] (8 ÷ 8) = 1 " ;

________

Rewrite the equation as:

________

 →  " [tex]\frac{(8 + 8x)}{8} =1[/tex]  "  ;

________

To solve:

________

Note:  " [tex]\frac{x}{y} = z[/tex] " ;  ↔ [tex]x = z*y[/tex] ; [tex](y\neq 0)[/tex] ;

________

 →  " [tex]\frac{(8 + 8x)}{8} =1[/tex]  "  ;  

 →  From the "left-hand side" of the equation;

      Let us simplify:

________

 →  " [tex]\frac{(8 + 8x)}{8} = \frac{8}{8} + \frac{8x}{8} = 1 + x[/tex] " ;  

Now, bring down the "1" from the "right-hand side" of the equation;

and rewrite the equation:

________

 →  " 1 + x = 1 " ;

Now, subtract "1" from each side of the equation;

   to isolate "x" on one side of the equation;

   & to solve for "x" :

________

     " 1 + x − 1 = 1 − 1 " ;

  → On the "left-hand side" of the equation:

          Note the following "like terms" :

            +1 − 1 = 0 " ;

  →  and we are left with "x" on the "left-hand side" of the equation.

  → On the "right hand side" of the equation:

         The "(1 − 1)" = 0 ;

  → And we are left with:

      →  " x = 0 " ;

      → which is the correct answer!

________

The correct answer is:  " x = 0 " .

Given, 720 mph = 720 miles per hour

Hour = 60

Equation: 60x = 5

1. 60 divided by 5 = 12

2. Since you found the x, divide the x (12) by 720

3. 720 divided by 12 = 60

What is the slope-intercept form of (-12,-6) (8,9)

Answers

Answer:y=3/20+12m+6

Step-by-step explanation: The equation for these types of problems are y=mx+b

the y is the second number, so in the first one the y would be -6, so you replace the y with the -6 and the x with -12

so now the equation is -6=-12m+b

you add the -12m to the other side to make 12m+6=b

now onto the second one, the 9 is the y and the 8 is the x, now the equation is 9=8m+b

this time you replace the b with the equation you got earlier (12m+6=b)

So the equation is 9=8m+12m+6

minus the 6 on both sides

3=8m+12m

add the m's

3=20m

3/20=m

Now you replace the m and the b

y=3/20x+12m+6

It is first down in a football game. Your team has the ball at your 25-yard marker, and the play is a successful run for 6 yards. A number line from ten to forty with labels at ten, twenty, thirty, and forty. Between each pair of labeled points are four tick marks. Where does the ball end up? Where is the ball relative to where it started? Use the number line to find the answer. Enter the correct answers in the boxes.

Answers

Using the theory of Number line in location linear distances, the final position of the ball is 31 yards while the relative position is 6 yards to the right of its initial position.

Initial position of the ball = 25 yards

Distance moved by the ball = 6 yards

Final position of the ball = Initial position + distance moved

Final position = (25 yards + 6 yards) = 31 yards

Final position of the ball relative to its starting position :

Since the ball moves to towards the right of the starting position, then the new position of the ball is 6 yards to the right of its starting position.

Therefore, the final position of the ball is 31 yards and it is 6 yards to the right of its starting position.

If I had seventeen 1/3s of pizza how many full pizzas could I make and how many thirds would be left over?

Answers

You would make 5 full pizzas and there would be 2/3 left over!

can anyone explain this to me?

Answers

Answer:

The missing side would be 6.

And the area would be 54.

Step-by-step explanation:

The perimeter equals 30, that's the outside of the rectangle. They give you a part of the perimeter, 9ft. So 9ft and there's another 9ft on the bottom line, (because it is equal to the top width) Which equals 18. To get the other sides you need to subtract 18 from the whole perimeter, 30. Which gives you 12. And there's two sides left, so divide by 2, and you have 6 on each side(left and right sides) Perimeter is adding all the sides up.

And the Area formula is Area=Length times Width. Area=9ft×6ft Which equals 54.
