Solve for x. 3x+1/14=2x/8

Answers

Answer 1

Answer: it depends if it is
1. 3x+(1/14)=(2x)/8 or
2. (3x+1)/14=(2x)/8

if it is 1

1.
3x+(1/14)=2x/8
simplify 2x/8
2x/8=x/4
3x+(1/14)=x/4
find least common multiple of 14 and 4
factors of 14=2 and 7
factors of 4 are 2 and 2 so LCM=2 times 2 times 7=28
multiply both sides by 28
84x+2=7x
subtract 7x from both sides
77x+2=0
subtract 2 from both sides
77x=-2
divide both sides by 77
x=-2/77

2.
(3x+1)/14=2x/8
simpify 2x/8
2x/8=x/4
(3x+1)/14=x/4
find least common multiple of 14 and 4
factors of 14=2 and 7
factors of 4 are 2 and 2 so LCM=2 times 2 times 7=28
multiply both sides by 28
(2)(3x+1)=7x
distribute
6x+2=7x
subtract 6x from both sides
2=x

Why is the answer to 12x12 the same as 6x24?

Answers

Both sets of numbers have the same factors:

12 × 12:

= (2× 2× 3) × (2 × 2 × 3)

= 2^4 × 3^2

6 × 24

= (2 × 3) × (2 ×2 × 2 × 3)

= 2^4 × 3^2

Graph (1,1), (1,2), (1,3), (1,4)

Answer:

There is not a way that I can show you how to graph it, so I will try and explain it.

Step-by-step explanation:

(1,1)

^ ^ y-axis

x-axis

You are just going right however many, and then up however many it says.

So if it's (1,1) you will go right one space, and then up one space.

Once you have all of your points on the graph, you put a line through them.

Hope this helps! :)

Answer:

Step-by-step explanation:

(Tangent Length)^2 = y*(y + 11) You are going to have to use the quadratic formula on this.

Tangent Length = 7

7^2 = y * (y + 11)

49 = y^2 + 11y

0 = y^2 + 11y - 49

a = 1

b = 11

c = - 49

When you solve this quadratic equation you get

x1 = 3.40 which is the answer you go with.

x2 = -14.40 which can't be used. A negative length has no meaning.

Towns A and B are 400 miles apart. If a train leaves A in the direction of B at 50 miles per hour, how long will it take before that train meets another train, going from B to A,
at a speed of 30 miles per hour?

Answers

from A :50/hour. *x(hour)
From B : 30/hour *x(hour)
50 *x +30 *x =400
80 *x=400
x=5(hour)
Then the train from A will make 50 *5=250 miles

The end points of one side of a regular pentagon are (-1,4) and (2,3). What is the perimeter of the pentagon?(1) the square root of 10
(2) 5 times the square root of 10
(3) 5 times the square root of 2
(4) 25 times the square root of 2

Answers

To determine the perimeter of the pentagon, you must first calculate a side length of it. Let's name the coordinates A(-1,4) and B(2,3).

To figure out how far the points are from each other, you have to use the distance formula:
$D_(AB) = \sqrt{( x_(2)-x_(1))^2+{(y_(2)-y_(1))^2}$
$x_(1) =1, x_(2) =-2, y_(1) =2, y_(2) =3$
$D_(AB)= \sqrt{(2--1)^2+{(3-4)^2}$
D_{AB}= \sqrt{(2--1)^2+{(3-4)^2}
$D_(AB)= \sqrt{(2+1)^2+{(3-4)^2}$
$D_(AB)= √((3)^2+(-1)^2)$
$D_(AB)= √(9+1)$
$D_(AB)= √(10)$

Now, the formula for the perimeter of a pentagon is
P = 5×side length

So...
Perimeter = 5× $√(10)$

The answer is (2)

the answer is (2) because using the distance formula which can be found on your browser, it will lead us to the answer 5 radical 10
