2x+4/5-6=8 I need help ASAP

Mathematics
1 answer:
Natasha2012 [34]3 years ago

Answer:

x=33/5

Step-by-step explanation:

Let's solve your equation step-by-step.

2x+4/5 −6=8

Step 1: Simplify both sides of the equation.

2x+4/5−6=8

2x+4/5+−6=8

(2x)+(4/5+−6)=8(Combine Like Terms)

2x+−26/5=8

2x+−26/5=8

Step 2: Add 26/5 to both sides.

2x+−26/5+26/5=8+26/5

2x=66/5

Step 3: Divide both sides by 2.

2x/2=66/5/2

x=33/5

WILL GIVE BRAINLIST do i do 10-x=2?​
Viktor [21]

Answer:

x = 4

Step-by-step explanation:

DE is parallel to AC and intersects the other 2 sides. It divides those sides proportionally, that is

\frac{BD}{DA} = \frac{BE}{EC}, thus

\frac{10-x}{x} = \frac{3}{2} ( cross- multiply )

2(10 - x) = 3x ← distribute left side

20 - 2x = 3x ( subtract 3x from both sides )

20 - 5x = 0  ( subtract 20 from both sides )

- 5x = - 20 ( divide both sides by - 5 )

x = 4

If a point is chosen inside the square, what is the probability that it will also be inside the circle?
Feliz [49]

Answer:

79\%

Step-by-step explanation:

The probability that the point is chosen in the circle is equal to the area of the circle divided by the area of the square.

Formulas used:

  • Area of a square with side length s is given by A=s^2
  • Area of a circle with radius r is given by A=r^2\pi

The segment marked as 1 represents not only the radius of the circle, but also half the side length of the square. Therefore, the side length of the square is 2, and we have:

Area of square: A=2^2=4

Area of circle:

A=1^2\pi=\pi

Therefore, the probability that the point will be inside the circle is:

\frac{\pi}{4}=0.78539816339\approx \boxed{79\%}
