The answer is 50/27 or 1 23/27 or approx 1.85185. Here is my work!

Multiply both sides by 10 : 20x + 6x = 50 - x

Collect the like terms: 20x + 6x = 50 - x

Move Variable to Left: 26x + x = 50

Collect like terms: 27x = 50

Divide both sides by 27: 50/27

Hope this helped :))

Step-by-step explanation:

S+T+U=180°{sum of angle of triangle}

68°+90°+U=180°
U=180-158°
U=22°

sin theta= p/h

sin22°=x/83

o.37=x/83

x=0.37×83

x=30.71

x=31

Given:
μ = 89 ng/ml, population mean
σ = 23 ng/ml, population standard deviation

Random variable, x = 100
To test P(x < 100), calculate the z-score.
z = (x-μ)/σ = (100 - 89)/23 = 0.4783

From standard tables, obtain
P(x < 100) = 0.6838 = 68.4%

Answer: 68.4%

Solve for x - Pre algebra

aniked [119]

In this case you would set it up as
$6x + 4x + 130 = 180$
(180 represents the degree of the triangle)

Add up like terms
$10x + 130 = 180$
Subtract 130 to the other side (180-130)

$10x = 50$
Divide 10 to the other side ( 50/10)
.
$x = 5$
Hope this was clear :)
