Elba and Jorge each make an error in the first two steps of solving the equation. 1/2(3x+4)-8=68-6(4/3+8x) Determine the error each student made. Then, solve the equation.

Answers

Answer 1

Answer:

x = 4 / 3  or  1.333  (Approx)

Step-by-step explanation:

Equation:

1/2(3x+4)-8=68-6(4/3+8x)

3x/2 + 4/2 - 8 = 68 - 24/3 - 48x

3x/2 + 2 - 8 = 68 - 8 - 48x

3x/2 + 48x = 66

By taking LCM

3x + 96x = 132

99x = 132

x = 132 / 99

x = 44 / 33

x = 4 / 3  or  1.333  (Approx)

What value of x satisfies the equation below?
12 ( x - 2 ) + 3 x = 1 2 ( x + 6 ) + 2

Answers

Answer:

x = 32.6666667

Step-by-step explanation:

12(x - 2) + 3x = 12(x + 6) + 2

Distribute;

12x - 24 + 3x = 12x + 72 + 2

Collect like terms;

15x - 24 = 12x + 74

Subtract 12x from both sides;

3x - 24 = 74

Add 24 to both sides;

3x = 98

Divide both sides by 3;

x = 32.6666667

Marian se deplaseaza ,cu automobilul,pe autostrada.La ora 10 si 35 minute el se afla la kilometrul 25 .Dupa un interval de timp,la ora 11 si 15 minute,el se afla la kilometrul 100.Calculati :durata deplasarii,distanta parcursa de Marian si viteza medie a acestuia(exprimata in unitati de SI)

Answers

Step-by-step explanation:

If Marian travels, by car, on the highway. At 10 and 35 minutes he is at kilometer 25. After a period of time, at 11 and 15 minutes, he is at kilometer 100.  

Total distance covered = 25km + 100km

Total distance covered by Marian = 125km

Total time taken by marian = 10hr 35min + 11hr + 15min

Total time taken by marian = (10+11)hr + (35+15)min

Total time taken by marian = 21hr 50mins

Total time taken by marian  = 21 * 50/60 hr

Total time taken by marian (Duration) = 21.833hr

Average speed = Total distance covered/Total time taken

Average speed = 125/21.833

Average speed = 5.725km/hr

Convert to m/s

5.725km/hr = 5.725*1000/3600

5.725km/hr = 5725/3600

5.725km/hr = 1.5903 m/s

Hence the average speed expressed in SI unit is 1.5903 m/s

Step-by-step explanation:

Answer:

y = 3x + 1

Step-by-step explanation:

You know the  y intercept by looking where the line hits the y axis, which is at (0,1), so you know the "b" of the equation is 1. Then, you do rise over run. If you rise 3 and run 1, you get to another point, so I know the slope is 3/1 or 3.

he length of a rectangle is five times its width.
If the perimeter of the rectangle is 120m , find its length and width.

Answers

Answer:

w = 10

l = 50

Step-by-step explanation:

Formula of Perimeter: w + w + l + l or 2w + 2l

l = 5w

2l + 2w = 120

2(5w) + 2w = 120

10w + 2w = 120

12w = 120

w = 10

l = 5(10)

l = 50

Check:

2l + 2w = 120

2(50) + 2(10) = 120

100 + 20 = 120

120 = 120

Hope This Helps!

Lets denote our variables as:

x the width of the rectangle5x the length of the rectangle

The formula for the perimeter of a rectangle is P = 2L + 2W, where L is the length of the rectangle and W is the width of the rectangle. We know that the perimeter of the rectangle is 120m, so we can write:

2(x) + 2(5x) = 120

2x + 10x = 120

12x = 120

 x = 120/12

 x = 10 m → Width of the rectangle

Substituting in the length:

5x = 5(10) = 50 m → Length of the rectangle

The length of the rectangle is 50 m and its width is 10 m.

Answers

Answer:

we have added 9/4 to both sides of the equation.

Step-by-step explanation:

The given equation is :

[tex]x^2+3x=6[/tex]

Here, a = 1, b = 3 and c = 6

We should add (b/2)^2 to the both sides of the equation.

(b/2)^2 = (3/2)^2 = (9/4)

[tex]x^2+3x+\dfrac{9}{4}=6+\dfrac{9}{4}\\\\(x+\dfrac{3}{2})^2=\dfrac{33}{4}\\\\x+\dfrac{3}{2}=\pm \dfrac{\sqrt{33}}{2}\\\\x= +\dfrac{\sqrt{33}}{2}-\dfrac{3}{2}, -\dfrac{\sqrt{33}}{2}-\dfrac{3}{2}\\\\=1.37,-4.37[/tex]

Hence, we have added 9/4 to both sides of the equation.

Let the time in travel for the first train be x, then we have equation for distance:

50x = 60(x - 3)50x = 60x - 18060x - 50x = 18010x = 180x = 18 hours
