If x + 4y = 6 and you subst. -x+3 for y, you get x + 4(-x+3) = 6.
Then x - 4x + 12 = 6, or -3x = -6, or x = 2. Since y = -x+3, here y = -(2)+3 = 1.
Thus, the solution to this system of linear equations is (2,1).

$112.25*.15= 16.8375
112.25-16.8375= 95.1625 *.15= 14.274375
95.1625-14.274375= 80.888125
$80.89 is the price.
Answer:
the volume is
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, a cylinder.
Given data
Volume v = ?
Radius r = r in
Height h= 2r in
We are expected to solve for the volume of a cylinder, given the above data we can substitute it in the formula for volume of a cylinder to obtain our result
we know that the expression for the volume of a cylinder is
Hence the volume in terms of the radius is
Answer:
50 grams
Step-by-step explanation:
You simply subtract 70 from 120, and get 50.
