w - width
6w - length
486 in² - area of the rectangle
(w)(6w) = 6w² - area of the rectangle
The equation:
6w² = 486 <em>divide both sides by 6</em>
w² = 81 → w = √81
w = 9 in
l = 6w → l = (6)(9) → l = 54 in
The perimeter: P = 2l + 2w
P = 2(54) + 2(9) = 108 + 18 = 126 in
<h3>Answer: The perimeter is 126in</h3>
Answer:
The second dealer is better.
Step-by-step explanation:
To figure this out we need to divide the price by the amount of milk. Lets do both at the same time.
3.8/2= 2.7/1.5=
3.8/2=1.9 2.7/1.5=1.8
The second dealer is better.
Answer:
30
Step-by-step explanation:
So to do this you would set up the equation 
than you would add 6 to both sides so you would get 
than you would divide 3 from both sides so 
and that is the final answer which is correct
Answer:
x = 9.2
y = 5.5
Step-by-step explanation:
y/5 = 6/y
y^2 = 30
y = 5.5
x/5 = 17/x
x^2 = 85
x = 9.2
The difference between your speed is 6 miles per hour: that means that every hour you move 6 miles relative to your friend. But you only need to catch up 3 miles: half of it. So you'll catch up after 30 minutes.
