Linear equations are written as y = C1x + C2 where C1 & C2 are
constants. They are graphed by plugging in numbers for y or x and solve
for the other. For example if you have an equation y = 3x + 6 you then
for y = 1 you have 1 = 3x + 6 -> x = -5/3 you then take the two
coordinates (-5/3,1) and plot the point do this for further numbers and
connect the points with a straight line. Shifting the graph up or down
will change the value of C2 and shifting the graph left or right will
change C1.
6(1/2 + 2/3 + 3/4)
= 6(1/2) + 6(2/3) + 6(3/4)
= 3 + 4 + 4 1/2
= 11 1/2
Answer
11 1/2 (23/2 or 11.5)
Each room has 2 walls that are 4x10 = 40 square feet and 2 walls that are 8x10 = 80 square feet. So 80+80+40+40 = 240 square feet of wall will be painted per room.
We use 2 coats of paint so in effect, we double the area. Imagine laying one thin wall on top of the other. The amount of paint area used per room doubles from 240 to 480
There are 4 of these rooms so 4*480 = 1920
The total area we need to paint is 1920 square feet
Divide this over 32 to get 1920/32 = 60
Final Answer: 60
