Step-by-step explanation:

there are

150 + 83 + 57 + 10 = 300 students in total.

so,

100% = 300

1% = 100%/100 = 300/100 = 3

150 / 3 = 50%

83 / 3 = 27 2/3 % or 27.66666...%

57 / 3 = 19%

10 / 3 = 3 1/3 % or 3.333333...%

Answer:54

Step-by-step explanation:

Pentagon has 5 sides

n=5

Sum of interior angles=180(n-2)

Sum of interior angles=180(5-2)

Sum of interior angles=180x3

Sum of interior angles=540

Size of each interior angle =540/n

Size of each interior angle =540/5

Size of each interior angle=108

x=108/2

x=54

Lots of point up for grabs

Burka [1]

Minus a from both sides
x-a=-2by²
times both sides by -1
a-x=2by²
divide both sides by 2b
$\frac{a-x}{2b}=y^2$
sqrt both sides
$y= \sqrt{\frac{a-x}{2b}}$

Two lines, A and B, are represented by the equations given below!

lara [203]

Answer:

The solutions to the system of equations are:

$y=-8,\:x=-4$

Thus, option C is true because the point satisfies BOTH equations.

Step-by-step explanation:

Given the system of the equations

$\begin{bmatrix}y=x-4\\ y=3x+4\end{bmatrix}$

Arrange equation variables for elimination

$\begin{bmatrix}y-x=-4\\ y-3x=4\end{bmatrix}$

$y-3x=4$

$-$

$\underline{y-x=-4}$

$-2x=8$

$\begin{bmatrix}y-x=-4\\ -2x=8\end{bmatrix}$

solve for x

$-2x=8$

Divide both sides by -2

$\frac{-2x}{-2}=\frac{8}{-2}$

$x=-4$

$\mathrm{For\:}y-x=-4\mathrm{\:plug\:in\:}x=-4$

$y-\left(-4\right)=-4$

$y+4=-4$

$y=-8$

The solutions to the system of equations are:

$y=-8,\:x=-4$

Thus, option C is true because the point satisfies BOTH equations.
