Answer:
Step-by-step explanation:
The permiter of a rectangle got be determined by the following equation:
P = 2L + 2W
where P is the perimeter, L is the length of the rectangle, and W is the width of the rectangle.
From the problem statement, we know that P = 60, and that the length is twice the width, so we have the following two equations:
60 = 2L + 2W
L = 2W
If we substitute the second equation into the first, we have the following:
60 = 2(2W) + 2W
60 = 4W + 2W
60 = 6W
10 = W
Plugging this value back into the second equation, we have the following:
L = 2W
L = 2(10)
L = 20
The area of a rectangle is determined by the following:
A = LW
where A is the area.
Plugging in the values that we determined previously we give you the answer.

Answer:
3 1/3
Step-by-step explanation:
Multiply both sides by the reciprocal of the coefficient of c.
(5/2c)(2/5) = (8 1/3)(2/5)
c = (25/3)(2/5) = 50/(3·5) = 10/3
c = 10/3 = 3 1/3
Answer:
Step-by-step explanation:
to go from (4, 3/4 ) to (6, 0) you need
a line with slope m= (y2-y1)/(x2-x1) = -0 / 4-6 =
use the quation of a line point-slope
(y-y1)=m(x-x1)
substitute m= -3/8 and (x1,y1) with (6,0)
Now does point (10,4) where is the aim is verified by this equation?
substitute x=10, y=4 in the equation to check
4= -3(10-6)/8
4= -3*4/8
4=-3/2 this is never true so you do NOT make the shot
