Plug in x = 12 and y = -5 into the given equation:-
3(12) - 3(-5) = 36 + 15 = 51 Not 21
So (12,-5) is not a solution.
X-5+5x-12=25
x+5x=25+5+12
6x=42
x=42/6
x=7
The answer is 222. 20 divided by 1 is 20 so if you divide 4440 by 20 you get 222.
Hope this helped!
Answer:
if you look at carefully the left triangle has two same side. so left-angle of C is 180-130=50 degree 5x+5x+50=180 x=13 degree
Step-by-step explanation:
for right triangle again one angle is 50 degree and other is 6*13-(3)=75 degree so 75+50+(10y+5)=180 degree y=5 degree
