4 0

Answer:

196 minutes

Step-by-step explanation:]

2x10 is 20 and if you divide 5/10 its 2 so the 4 in 4/5 is the total of 8 because 10 would mean 5/5 and 20+8=28 so 28x7 is 196

The sum of the measures of the interior angles of a polygon with n sides is

defon

ANSWER

$(n - 2) \times 180 \degree$

EXPLANATION

The sum of the interior angles of a triangle is 180°

We can rewrite this as:

$1 \times 180 \degree = (3 - 2) \times 180 \degree = 180 \degree$

The sum of interior angles of a quadrilateral is 360°

We can also rewrite this as:

$2 \times 180 \degree = (4- 2) \times 180 \degree = 360 \degree$ In general an n-sided polygon has

the sum of the interior angles given by the formula:

$(n - 2) \times 180$

-1(x+5)=3[x+(2x-1)]<br> solved and justified each step

madreJ [45]

Answer:

Step-by-step explanation:

$-1(x+5)=3[x+2x-1)]\\\\\text{for}\ -1(x+5):\ \text{distribtutive property}\\\text{for}\ [x+(2x-1)]:\ \text{associative property}\\\\(-1)(x)+(-1)(5)=3[(x+2x)-1]\\-x-5=3(3x-1)\\\\\text{for}\ 3(3x-1):\ \text{distributive property}\\\\-x-5=(3)(3x)+(3)(-1)\\-x-5=9x-3\\\\\text{for the equation}:\ \text{addition property of equality}\\\\-x-5=9x-3\qquad\text{add 5 to both sides}\\-x-5+5=9x-3+5\\-x=9x+2\\\\\text{for the equation:}\ \text{subtraction property of equality}\\\\-x=9x+2\qquad\text{subtract}\ 9x\ \text{from both sides}$

$-x-9x=9x-9x+2\\-10x=2\\\\\text{for the equation:}\ \text{division property of equality}\\\\-10x=2\qquad\text{divide both sides by -10}\\\dfrac{-10x}{-10}=\dfrac{2}{-10}\\x=-0.2$

$\text{Distributive property:}\ a(b+c)=ab+ac\\\text{Associative property:}\ (a+b)+c=a+(b+c)$
