The area of the rectangle is 47 1/2
Y = mx + b
m = (0 - -5)/(6 - 3) = 5/3
y = 5/3x + b
0 = 5/3(6) + b
b = -10
(y = 5/3x - 10)3
3y = 5x - 30
3y - 5x = -30
5x - 3y = 30
X = 4
EXPLANATION:
45/60 can be simplified by dividing both 45 and 60 by the same number.
We already know the numerator is 3.
so we have to do the equation 45 divided by 3. which is 15.
so now we do 60 divided by 15 to find x.
So x = 4
82 = 100%
10% discount (90% of original price)
To find 90% find 10% and then subtract it from 82)
10% = 82/10 (8.2)
80-8.2=
71.8
