9 * r = 81
9r = 81
divide both sides by 9
r= 81/9
r = 9
-4
Step-by-step explanation:
-4z² + z²
let's assume you have z² and you're owing 4z², you'll pay the z² you have and you'll still owe 4
so that is -4
210 days* (1 week/ 7 days)* (50 inches/ 100 weeks)= 15 inches.
(Note that the units cancel out so you get the answer)
Final answer: 15 inches~
