Answer:
n = 9
Step-by-step explanation:
Step 1: Write equation
-4(9n + 9) = -12(4n - 6)
Step 2: Solve for <em>n</em>
<u>Distribute:</u> -36n - 36 = -48n + 72
<u>Add 48n to both sides:</u> 12n - 36 = 72
<u>Add 36 to both sides:</u> 12n = 108
<u>Divide both sides by 12:</u> n = 9
Step 3: Check
<em>Plug in n to verify if it's a solution.</em>
-4(9(9) + 9) = -12(4(9) - 6)
-4(81 + 9) = -12(36 - 6)
-4(90) = -12(30)
-360 = -360
Answer:
-8 hours/week
Step-by-step explanation:
Erik = 4 hours/week
Little Brother = 12 hours/week
How many more hours does Eric ride his bike during the week than his little brother?
Erik - Little Brother = (4 hrs/wk - 12 hrs/wk)
Erik rides his bike -8 hours/week more than his little brother.
2 nights. 2/3 plus 2/3 is already more than 1 whole, so he finishes reading one book in 2 days. Since he also reads four books, but also 2/3 of it in one day, the answer still remains the same: 2 nights. Hope this helps! Please rate brainiest answer!
