Solve the equation<br> 3x-2<br> 4<br> -<br> 2x - 5- 1 + x<br> 3 6
Nataly_w [17]

Answer:

  • \boxed{\sf x=12}

Step-by-step explanation:

\sf \cfrac{3x-2}{4}-\cfrac{2x-5}{3}=\cfrac{1+x}{6}

First, let's find the LCM of 4, 3, and 6.

<u>How to find the LCM:</u>

→ List multiples of each number.

→ Find the smallest number on each list.

4: 4, 8, 12, 16, 20, 24..

3: 3, 6, 9, 12, 15, 18, 21, 24, 27....

6: 6, 12, 18, 24, 30, 36, 42...

<u>LCM: 12</u>

<u>_________</u>

Now, we'll Multiply by LCM:

\sf \cfrac{3x-2}{4}\times \:12-\cfrac{2x-5}{3}\times \:12=\cfrac{1+x}{6}\times \:12

Simplify:

\sf 3\left(3x-2\right)-4\left(2x-5\right)=2\left(x+1\right)

Now, expand, Apply the Distributive property:

\bold{ 3\left(3x-2\right)-4\left(2x-5\right)}

\sf  9x-6-8x+20

Combine like terms:

\sf x+14

________

\bold{ 2\left(x+1\right)}

\sf 2x+2

\sf x+14=2x+2

Subtract 14 from both sides:

\sf x+14-14=2x+2-14

Simplify:

\sf x=2x-12

Subtract 2x from both sides:

\sf x-2x=2x-12-2x

Simplify:

\sf -x=-12

Divide both sides by -1:

\sf \cfrac{-x}{-1}=\cfrac{-12}{-1}

\sf x=12

Help please?????????????????
son4ous [18]
This is Pythagorean theorem. 
We already know a and c. 
a = 4 and c = 10
4² + b² = 10² 
16 + b² = 100 
Subtact 16 from each side. 
b² = 84 
Square root of each side: 
b = ≈9.165 or √84

Hope this helps!

Brenda throws a dart at this square-shaped target: Part A: Is the probability of hitting the black circle inside the target clos
Masteriza [31]
Either way.  The probability of hitting the circle is:

P(C)=Area of circle divided by area of square

P(W)=(area of square minus area of circle divided by area of square

P(C)=(πr^2)/s^2

P(W)=(s^2-πr^2)/s^2

...

Okay with know dimensions, r=1 (because r=d/2 and d=2 so r=1), s=11 we have:

P(inside circle)=π/121  (≈0.0259  or 2.6%)

P(outside circel)=(121-π)/121  (≈0.9744 or 97.4%)
