Answer:
Nickel = 12
Quarters = 26
Step-by-step explanation:
Given
<em>Represent Nickel with N and Quarters with Q</em>
--- <em>It's 14 more quarters; not 143</em>
Required
Determine the quantity of each coin
First, we have to know that:
-- (1) ---- By converting N and Q to dollars;
Substitute 14 + N for Q in (1)

Answer:
x and y is 115 exterior angle property
Answer:
4
Step-by-step explanation:
The median is the middle number when the list is sorted from least to greatest or greatest to least.
We make this list to get 2,3,4,5,8 or 8,5,4,3,2 and the middle number in both lists is 4.
Answer:
y=90
Step-by-step explanation:
y is a right angle, and all right angles are 90 degrees! Please mark brainliest and press the thanks button! :)
<span>First, we write an equation to represent that the fencing lengths add up to 568 feet. we call the side of the fence that has three segments of its length x and the side with only two segments y. We write 3x + 2y = 568. We also know that the area of the rectangle is equal to xy, so area = xy. We put y in terms of x using our first equation and find that y = (568 - 3x)/2. We plug this into our area equation and find that area = (568x - 3x^2)/2. To find the maximum we set the derivative equal to 0 and end up with 0 = 284 - 3x. We solve for x and get 94 and 2/3. We then put that into our first equation to find y = 142. So the dimensions that maximize the area are 94 2/3 x 142.</span>
