Answer:
Graham: -50x + 14,040
Max: 20x + 12,500
Graham = Max
-50x + 14,040 = 20x + 12,500
+50x +50x
14,040 = 70x + 12,500
-12,500-12.500
1,540 = 70x
220 = x
Answer: 220 minutes (3 hours 40 minutes)

Answer:
Not proportional
Step-by-step explanation:
If x and y are proportional then the equation relating them is
y = kx ← k is the constant of proportionality
To determine if x and y are in proportion then k must be equal for all ordered pairs, that is
k = 
(2, 0) k = 
= 0
(4, 2) → k = 
= 
(6, 4) → k = 
= 
(8, 6) → k = 
= 
Since k is not constant for all values then not in proportion
Answer:
16,000
Step-by-step explanation:
20,000 x .20 = 4,000
20,000 - 4,000 = 16,000
Answer:
the room square side is 4.8m
Area of the room is= 4.8=²23.04²m
perimeter of square tiles=4a =1.2
a=1.2/4
or a=o.3m
area of the square tiles =0.3²=0.09m²
numbers of the tiles are rcover floor of the room
23.0.4/0.09=256
each tiles cost Rs 27
the total cost=256*27=6912
the th coalst cover by the th floor is Rs .6912
