Divide the numerator by the denominator so for example if you had 1/2 you would divide 1 by 2 to get 0.5
Answer:
the equation is equivalent, y is any number
Step-by-step explanation:
-3(3y-7) = 21-9y
-9y + 21 = 21 - 9y
-9y = -9y
y=y
any number will satisfy y=y
The answer is 4.2 because you have to replace r with -14.1 and s with 18.3. After that you subtract them and you get 4.2
<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>
X = 10 per set dishes, and y = 35 per set dishes
x + y = 200....x = 200 - y
10x + 35y = 4250
10(200 - y) + 35y = 4250
2000 - 10y + 35y = 4250
-10y + 35y = 4250 - 2000
25y = 2250
y = 2250/25
y = 90 <=== he got 90 of the $ 35 dishes
x + y = 200
x + 90 = 200
x = 200 - 90
x = 110 <=== he got 110 of the $ 10 dishes
