Suppose that this person drives at r mph going to the mountains, and gets there in 12 hours. Returning, this person drives at (r+20) mph and gets home in 8 hours. We don't know the distance yet, but can solve for the initial speed, r, by setting
d = 12r = (r+20)(8). Solving for r, r=40 mph (going) and (40+20)mph = 60 mph (returning. Since d=12 r, d = (12 hrs)(40 mph) = 480 miles (answer).
Answer: 
Step-by-step explanation:
<h3>A glass of lemonade took 2 1/2 scoops of sugar to make in it. If you wanted to make 3 glasses how many scoops of sugar would you need</h3>
<h3>
</h3>
<h3>First,</h3><h3>Change the fraction to decimal. 2½=2.5</h3><h3 /><h3>Second,</h3><h3>Simply Multiply it by 3! 2.5×3=7.5</h3>
<h3>Therefore, you need 7.5 (7½) scoop of sugar to make 3 glasses of lemonade.</h3>
Answer:
Slope (m) =ΔY
/ΔX
=-3/
1
=-3
n slope = -3
From equation [<u>-2</u>x-8]
m slope = -2
so B) m>n
