(n*3)+6-(n*2)=n+3
3n+6-2n=n+3
3n-2n-n=3-6 every n on the left and free numbers on the right
0=-3
contradiction, there are no solution
Answer:
The equation is:
Step-by-step explanation:
Given the endpoints of a side of a rectangle
Finding the slope
Using the point-slope form of a line equation
substituting the values m = -1 and the point (1, 6)
Thus, the equation is:
Number of golfers that didn't qualify = 30
Explanation:
Total number of golfers = 80
The percentage that qualified for the next round = 62.5% = 0.625
Number that qualified = 80 * 62.5%
= 80 * 0.625
Number of golfers that qualified = 50
Number of golfers that didn't qualify = Total number of golfers - Number of golfers that qualified
= 80 - 50
Number of golfers that didn't qualify = 30
Ok lets do this like this:
<span>Let x = length
Let y = width
From this we know that area A=xy.
</span><span>Now, perimeter is P=2x+2y
cost would be 3(2x)+2(2y) or 6x +4y=$6,000.00.
From this cost equation we solve for x in terms of y
6x=6000-4y
x=1000-(4y)/6.
</span>now lets substitute this value in the area equation A=xy.
A=(1000-4y/6)y
<span>A=1000y−4<span>y2</span>/6=1000y−2<span>y2</span>/3</span>
differentiate and set to equal zero (0)
<span>1000−(−4y/3)=0</span><span>
Solve for y and obtain y=750ft</span>
