Answer:
She has 24,50$ left
Step-by-step explanation:
3,50*5 = 17,50
42$ - 17,50$ = 24,50$
34.5=4h+7c
(34.5-7c)/4=h
Put h= (34.5-7c)/4 into another equation
30.5=8h+3c
30.5=2(34.5-7c)+3c
30.5=69-14c+3c
11c=38.5
c=38.5/11
Put c=38.5/11 into one of the equations
to calculate the h.
Answer:
3x/4
Step-by-step explanation:
that's what I found. It would be better if u had more details in your question.
So we can subsitute since they all equatl zero
1/2+n=0=2/3+n
1/2+n=2/3+n
subtract n from both sides
1/2=2/3
false statement
therefor there is no solution
