100/x=60/30 so x=100*30/60=50
Answer: she can rent a boat or 2 hrs and 30 mins
Step-by-step explanation:
60+10=70
70+60=130
130+60=190
190+30=220
It's called "solve the equation for 'y' ". That means move things
around so that you end up with 'y' all alone on one side, and
everything else on the other side.
You started with 9x - 7y = -7
Subtract 9x from each side: - 7y = -9x - 7
Divide each side by -7 : y = 9/7 x + 1
Sorry if I'm wrong but I think the answer is B
Answer:
e=g = 126 degree
Step-by-step explanation:
e = g (opposite angles's property)
g+ b = 180 ( supplementary angles's property)
b = 54 degree (opposite angles's property)
-> g = 180-54 = 126
-> e = 126 degree
