-9x=16-y equation 1
12x=-5-y equation 2
x=-5-y÷12 from equation 2
substitute this x in equation 2
so
-9(-5-y÷12)=16-y
15+3y=64-4y
7y=49
y=7
and then substitute this value of y in equation (x=-5-y÷12)
so x= -5-7÷12
x=-1
so y=7 and x=-1
Answer:
36 minutes
Step-by-step explanation:
If I read this correctly, Dracula jumps 1 time every 6 minutes. If he jumped 5 times in 30 minutes, then that means when he jumped a sixth time, it was 36 minutes that passed since:
30 / 5 = 6
So, if he were to jump a sixth time:
30 + 6 = 36
Therefore, Dracula jumps 1 time per 6 minutes.
