Using substitution x+3y=3 3y-2x=12

frez [133]

Step-by-step explanation:

Given :-

x + 3y = 3
3y - 2x = 12

And we need to solve the equation using Substituting method . So on taking the first equation ,

$\rm\implies x + 3y = 3 \\\\\rm\implies x = 3 - 3y$

Put this value in (ii) :-

$\rm\implies 3y - 2x = 12 \\\\\rm\implies 3y - 2(3-3y)=12\\\\\rm\implies 3y -6-6y = 12 \\\\\rm\implies -3y = 18 \\\\\rm\implies y = -6$

Put this Value in (I) :-

$\\\\\rm\implies x = 3-3*-6 \\\\\rm\implies x = 3+18 \\\\\rm\implies x = 21$

Hence the Value of x is 21 and y is (-6) .

If a polygon has an interior angle of 144, what kind of polygon is it? (find the # of sides first

ikadub [295]

Each Interior Angle = ((Number of Sides -2) • 180 degrees) ÷ (Number of Sides)

Solving for number of sides

Each Interior Angle / 180 = (N -2) / (N)

144 / 180 = (n-2) / n

144 * n = 180n -360
360 = 36 n

n = 10 the number of sides
