The answer should be that the angles stayed the same.
An example for this would be a right angle. If you double the size of a right angle, the angle itself does not change. The size might, but not the angle itself. It is still going to be a right angle. This is the case with all other angles.
So this question can be representd by
eight times a number, (8x), is subtracted from (-8x) eleven times a number (11x), the result is -9
so -8x+11x=-9 or
11x-8x=-9
add like terms
3x=-9
divide both sides by 3
x=-3
Dood its like multiplication dood how many times can 7 go into 48.....im r.e.t.a.r.d.e.d
14) -5(x+1)>20;
-5x-5>20;
-5x>20+5;
-5x>25 ;
-x>5
& x< - 5
15-1) 2.5+y < 7.5
y< 7.5 - 2.5
y<5 (answer c)
15-2) y/18<1/6 (cross multiplication):
6y<18
y < 3 (answer d)
15-3) y-1.5> - 0.5
y> - 0.5 +1.5
y> 1 (answer b)
15-4) -1.5y<4.5
- y < 4.5/1.5
- y< 3
y> -3 (answer a)
(x^m)^3=(x^13)^5X(x^-8)^-5 would equal 35.
