The slope is 1/2 because for every time it up 1 unit it goes 2 units to the right
X + y = 20 ---> x = 20 - y
2.5x + 3.7y = (3.5)(20) = 70
--> 2.5(20-y) + 3.7y = 70
--> 50 -2.5y +3.7y = 70
--> 1.2y = 20
---> y = 16.66
Answer: 16.66 gallons
Answer:
she would have to pay about $88.49
Step-by-step explanation:
128.25x.35=44.8875
128.25-44.8875=83.3625
128.25x.04=5.13
83.3625+5.13=88.4925
Please, use " ^ " to denote exponentiation: p(t) = t^2 + 5t + 6.
To find the critical points, differentiate p(t) with respect to t, set the result = to 0, and then solve the resulting equation for t:
p '(t) = 2t + 5 = 0
Solving for t: 2t = -5, and so t = -5/2. (-5/2, p(-5/2)) is the critical point. That evaluates to (-5/2, -0.25). This happens to be the vertex of a parabola that opens up.

Answer: Choice C is correct</h3>
Explanation:
We can think of the square in the middle of the four others as the floor
The surrounding four squares are the walls that fold upward.
The square at the very right side will then form the ceiling.
Side E and side L join at the top left edge.
See the diagram below.
