Answer:
there is no answer ( I mean this system of equations can't be solved)
Step-by-step explanation:
Because the x eliminates itself there will be no point.
Let's solve your equation step-by-step.
-2/3p+ 1/6= 7/10
Answer:
p= -4/5
Answer:
54%
Step-by-step explanation:
Answer: 24:34
Step-by-step explanation:
If you multiply the ratio by 2, for example, it will still be equal.
From cosine law
c^2 = a^2 + b^2 -2abcos(C)
cos(C) = (a^2 + b^2 - c^2)/2ab
this formula will solve your problem
