3x = 24 You are not supposed to subtract 3 from x, you are supposed to divide instead. So you will divide each side by 3.
So it would be:
x = 8
Im not sure if its +9y or -9y but ill use +
-11x + 9y = -12 add 11x to both sides
9y = -12 + 11x. divide all numbers by 9
y = -12/9 + 11/9x. simplify -12 and 9 by 3
y = -4/3 + 11/9x. make sure its in slope intercept form (y=mx+b)
y = 11/9x - 4/3
slope: 11/9
y int: -4/3
I think that y=-1x-4 is the answer
170÷100=1.7
1.7×40=68
Answer: 68
It is based off of the angles of the triangle and the sides.
A triangle with a right angle (90°) is a right triangle.
A triangle with an angle larger than 90° is an obtuse triangle.
A triangle with angles that are smaller than 90° is an acute triangle. ALL ANGLES MUST BE SMALLER THAN 90°...
With sides, if a triangle has two angles that equal the same length, it is an isosceles triangle.
If NO sides are of equal length, it is a scalene triangle.
And if ALL sides are equal, then it is a equilateral triangle.
