Can anyone tell me what x equals in this scenario. 3/4x=2x-5

Dvinal [7]

Hey There!

The answer to your problem is $x=4$

Subtract 2x from both sides

$3/4x-2x=2x-5-2x$

$-5/4x=-5$

Multiply both sides by 4/(-5)

$(4/-5)*(-5/4)$ x $=(4/-5)*(-5)$

The olympics are held every four years. In 2016, the XXXI olympiad were held in Rio de Janeiro,Brazil. Determine the year of the

Anna007 [38]

Answer:

First Olympic held in year 1896.

Step-by-step explanation:

Number of Olympiad held in Rio = XXXI = 31st

Difference of years in two consecutive Olympiads = 4 years

Number of years spent in 31 Olympiads can be calculated by,

Number of years spent = (n - 1)d

Here n = number of Olympiads held

d = difference between two consecutive Olympiads

Number of years spent till 31st Olympiads = (31 - 1)×4

= 120 years

Therefore, 1st Olympiad held in the year = 2016 - 120

= 1896

What is mKNL? Enter your answer in the box.

sergejj [24]

Answer:

102°

Step-by-step explanation:

As the vertically opposite angles are equal,

$5x+2={3(x+14)$

Now let's solve for x now

$5x+2=3(x+14)\\$

$5x+2=3x+42$

$5x-3x=42-2$

$2x=40$

$\frac{2x}{2} =\frac{40}{2}$

$x=20 \\$

Now let's find the value of KNL

$3(x+14)\\3(20+14)\\3*34\\102$

Hope this helps you.

Let me know if you have any other questions ;-)

A conical paper cup has dimensions as shown in the diagram. How much water can the cup hold when full?

dusya [7]

By definition, the volume of a cone is given by:
 $V = (1/3)*( \pi)*(r^2)*(h)
$
 Where,
r: radius of the circular base of the cone.
h: cone height
The cone radius is given by:
 $r = d / 2 
$
 Where,
d: diameter of the circular base.
Substituting values we have:
 $r = 6/2 

r = 3 cm$ 
Then, the volume will be:
 $V = (1/3) * (3.14) * (3 ^ 2) * (10) 

V = 94.2 cm ^ 3$ 
Answer:
The volume of the cone is given by:
 $V = 94.2 cm ^ 3$
