I will rewrite the wording and write out the equation as it goes so there is better understanding. Once I do that, I will solve it for you. Nine times a number (9n) is (=) one more than ten times the number (10n + 1). Now that we've rewritten it, let's only write what we have in parenthesis. 9n = 10n + 1. Now that we have our equation, let's solve! 9n = 10n + 1 Subtract 10n from both sides. -1n = 1 Divide both sides by -1. n = -1 I hope this helps!
1/6 of an hour is 10 minutes because there are 60 minutes in an hour so 60/6=10 so it's 25m^2/10minutes now just multiply 25 by 12 ( 12 lots of 10 minutes in 2 hours) 25*12=300 answer is 300m^2
You only need the surface area, which means you will not use cubed (^3). But the surface area is two dimensions (length and width). SO you must use m^2.
