Answer:
105
Step-by-step explanation:
n=105 as 20 more than 105 is 125. Hope it helps!
First set up the equation based on the description.

x + 16 = 3x
Use subtraction to get the "x"s on one side of the equation. You can next subtract <span>

x from both sides.
16 = </span>

<span> x
Now you can multiply both sides of the equation by </span>

<span> to solve for x
x = 6</span>
Step 1: set up equation
-2x+y=3
Step 2: add 2x to both sides
-2x+y=3
+2x +2x
<u>
y=3+2x</u>
Hope this helps :)
Answer:
?= 35.66º
Step-by-step explanation:
26/32=0.8125
cos 35.66º=0.8125
Area is equal to length times width. The perimeter (the amount of rope) has to equal twice the length added to twice the width so we're left with:
A = l * w
200 = 2l + 2w
solve for either l or w
l = 100 - w
plug into the area equation to get one equation with two variables
A = w(100 - w)
A = -w^2 + 100w
take the derivative
A' = -2w + 100
set the derivative equal to zero
0 = -2w + 100
2w = 100
w = 50
This is the width that maximizes the area
with a width of 50, the length must also be 50 to have a perimeter of 200
therefore, they can rope up to 50 * 50 = 2500 ft^2
