What I did was 27.99-21.59 which equals 6.40 and then times that by 12 which brings you to 76.80
Let the time Larry spend reading be x and the time he spend watching TV be y. Then
x + y ≤ 4 . . . (1)
x ≥ y . . . (2)
The
graph represents two straight lines with one line passing through
points (0, 4) and (4, 0) and the other one passing through points (0, 0)
and (2, 2). The two lines intersects at point (2, 2) with the portion
of the graph bounded by the x-axis shaded.
Okay, for this one I would use elimination:
8x+(-2y)-10
or
8x-2y=10
2x=4y
x=2y
8(2y)-2y=10
16y-2y=10
14y=10
y=5/7
x=10/7 or 1 3/7. Hope it help!
